DU SIM Balance Check Code: The Ultimate 2026 Guide for UAE Prepaid and Postpaid Users

Every du sim balance check code you need in one place — covering USSD methods, SMS options, the du mobile app, online portal, customer care, and expert tips for both prepaid and postpaid users in the UAE.

Living and working in the UAE means staying connected is not just convenient — it is a daily necessity. Whether you are rushing through the Dubai Metro, attending a business meeting in Abu Dhabi, or streaming entertainment after a long shift in Sharjah, your mobile connectivity determines the quality of your digital life. DU, officially known as Emirates Integrated Telecommunications Company, is one of only two major telecom operators in the United Arab Emirates, and millions of residents, tourists, and business professionals rely on it every single day.

Yet, one of the most frustrating experiences any mobile user can face is running out of credit or data at a critical moment — in the middle of a Zoom call, while navigating an unfamiliar street, or just when you need to make an urgent payment. The solution is simple but essential: know how to check your balance before your connection drops. Knowing the du sim balance check code means you can monitor your credit, data, and remaining minutes at any time, without guesswork, without surprises, and without service interruptions.

This guide covers everything you need to know — from the quickest USSD shortcode to advanced account management via the DU app and web portal. Whether you are a first-time DU user still learning the ropes or a long-term UAE resident looking for a complete 2026 update, this article has been crafted with depth, clarity, and practical detail to serve every type of DU customer.

Understanding DU’s Telecom Ecosystem in the UAE

Before diving into the specific balance inquiry methods, it helps to understand who DU serves and what kinds of plans are available. DU was established in 2006 and rapidly expanded to become a primary telecommunications provider across all seven Emirates. Today, it offers a wide range of services including prepaid SIM cards, postpaid mobile plans, home broadband, business internet, and eSIM options.

DU’s customer base is diverse: tourists buying a prepaid SIM at the airport, expatriate workers relying on monthly postpaid plans, students using budget data bundles, and corporate clients managing multiple business lines all fall under the DU network. This diversity means that the tools available for balance monitoring must be flexible, and fortunately, DU provides exactly that — multiple methods to suit every lifestyle, device type, and level of technical comfort.

Understanding which plan type you are on is the first step to choosing the most effective balance monitoring method:

Prepaid SIM Users pay in advance for their service. They top up a credit balance and use it for calls, SMS, and data. Monitoring remaining credit is especially important for these users since service automatically stops when the balance hits zero.

Postpaid SIM Users pay a monthly bill after usage. While they are less likely to lose connectivity mid-month, they still need to track data consumption to avoid overage charges, especially if their plan has a data cap.

Tourist SIM Users typically receive a fixed data allowance upon purchase and need to monitor usage carefully over a short period.

Business SIM Users may manage multiple numbers under a single corporate account and require bulk monitoring tools.

No matter which category you fall into, the du sim balance check code and other methods described below apply directly to your situation.

Method 1: The USSD Code — Fastest and Most Reliable

The quickest and most universally trusted method for checking your DU balance is dialing a USSD (Unstructured Supplementary Service Data) code directly from your phone’s dialer. This method works on any mobile device — whether it’s a basic feature phone, an Android smartphone, or an iPhone — and crucially, it requires no internet connection whatsoever.

What Is a USSD Code?

USSD codes are short strings of characters that communicate directly with DU’s network servers through your SIM card. They bypass the internet entirely, operating through the GSM cellular network, which means they function even when you have no data balance, no Wi-Fi connection, and even in areas with limited signal strength (though at least a minimal signal is needed for the request to be transmitted).

The Primary DU Balance Check USSD Code

The main du sim balance check code that every DU user in the UAE should memorize is:

*135#

Here is the exact step-by-step process to use it:

1. Unlock your phone and open the Phone or Dialer application.
2. Type *135# using your keypad exactly as written.
3. Press the Call button (or the green send button on your device).
4. Wait a few seconds — typically between two and five seconds.
5. A pop-up flash message will appear on your screen displaying your current account credit, remaining data, and other relevant details.

This method is completely free of charge. DU does not deduct any credit for using the USSD balance inquiry service, meaning you can check your balance even when your account is at zero. The information displayed typically includes your remaining call credit in AED (UAE Dirhams), your remaining data in MB or GB, and the expiry date of your current plan or credit. card services prepaid card inquiry

Additional USSD Codes for DU Users

While *135# is the primary du sim balance check code, DU offers several supplementary USSD codes for more specific inquiries:

Service	USSD Code	Description
Main balance check	*135#	Prepaid and postpaid credit and data summary
Data balance only	*102#	Remaining internet data and validity
SIM number inquiry	*116#	Displays your own DU mobile number
Internet data balance	*1355#	Specific data usage details
Customer care	155	Voice-guided account support

For prepaid users who primarily want to check remaining mobile data without navigating a menu, dialing *102# provides a direct, simplified response. A pop-up notification will display your total remaining data in MB or GB along with the exact expiry date and time of your current data bundle — information that is particularly useful if you are on a daily, weekly, or monthly internet plan.

How USSD Works on Dual-SIM Phones

If you are using a dual-SIM smartphone — which is very common among UAE residents who maintain both a personal and a work number — make sure you are initiating the USSD call from the correct SIM slot. Most Android phones will ask you which SIM to use when dialing, while some automatically use the default SIM. Check your phone’s SIM settings and designate your DU SIM as the preferred calling SIM if you use DU as your primary network. iPhones with dual-SIM support typically show a prompt when you dial USSD codes, asking which line to use.

Method 2: SMS Balance Check — Simple and Effective

For users who prefer text-based interactions over interactive pop-up menus, SMS provides an equally reliable and straightforward balance monitoring option. The SMS method is ideal when you want a text record of your balance delivered to your inbox, when USSD menus feel too navigation-heavy, or when you simply prefer sending a quick message.

How to Check DU Balance via SMS

To check your prepaid credit balance by SMS, follow these steps:

1. Open the Messages or SMS app on your mobile phone.
2. Create a new message.
3. In the recipient field, type 1355.
4. In the message body, type BAL or BALANCE (either works; the system is not case-sensitive).
5. Send the message.

Within seconds, DU’s automated system will send you a reply SMS with your current credit balance, remaining data, and usage details. The information is presented clearly in text format, which you can screenshot, save, or refer back to later.

For those who want to check data balance specifically, the process is the same — type BAL or BALANCE and send it to 1355. The reply will include your remaining internet data and its validity period.

An alternative number used by some DU services is 1335. If you are sending balance inquiries for specific data bundles or older plan types, try sending your message to 1335 as well, following the same format. Both numbers are part of DU’s self-service SMS infrastructure and are free to use.

SMS for Postpaid Users

Postpaid DU users can send Rewards to 1233 via SMS to receive a breakdown of their remaining data, minutes, and plan details. This is particularly useful for users subscribed to loyalty or rewards-based postpaid plans, as it also provides information on any bonus benefits or accumulated points tied to their account.

Method 3: The DU Mobile App — Most Feature-Rich Option

For UAE residents who are comfortable with smartphones and want a comprehensive, visually intuitive account management experience, the official DU mobile application is the most powerful tool available. The app goes far beyond simple balance checking — it is a full-service account hub that lets you monitor, manage, top up, and customize every aspect of your DU mobile service.

Downloading and Setting Up the DU App

The DU app is available for free on both major mobile platforms:

• Android users: Search for “DU” or “DU UAE App” in the Google Play Store.
• iPhone users: Search for “DU” in the Apple App Store.

Once downloaded and installed, open the app and register using your DU mobile number. During registration, you will receive a one-time password (OTP) via SMS on your DU number — enter this OTP in the app to verify your identity and complete the setup. If you already have a DU account registered online, you can log in using your existing credentials.

Checking Balance on the DU App

After logging in, the home screen or dashboard will immediately display your account overview, which includes:

• Current credit balance (in AED for prepaid users)
• Remaining data balance (in MB or GB)
• Remaining call minutes (if your plan includes a calling bundle)
• Remaining SMS quota (if applicable)
• Validity and plan expiry dates
• Active subscriptions and add-ons

The information updates in real time, meaning the figures you see reflect your actual current usage at the exact moment you open the app. This is particularly valuable for postpaid users who want to track their monthly data consumption against their plan limit, since the app shows unbilled usage and cycle-to-date figures clearly.

Additional Features of the DU App

Beyond balance monitoring, the DU mobile app offers a suite of management tools:

Top-Up and Recharge: Prepaid users can reload their account directly through the app using a credit card, debit card, or digital wallet — no need to buy a physical top-up card or visit a store.

Bundle Purchase: Both prepaid and postpaid users can browse and activate additional data bundles, international calling packs, or special promotional offers directly from the app.

Bill Payment: Postpaid users can view their monthly statement, see a detailed breakdown of charges, and pay their bill in-app within minutes.

Usage Alerts: The app allows you to set automatic notifications that alert you when your data consumption reaches 80% or 100% of your plan allowance — a proactive way to avoid overage charges without needing to manually check your balance every time.

Chatbot Support: The DU app includes an AI-powered chatbot that responds to balance inquiries in natural language. Simply type “Check my data balance” or “What is my remaining credit?” and the chatbot provides an immediate response, available 24 hours a day, seven days a week.

Multi-Number Management: For business users or households managing multiple DU lines, the app allows you to add and switch between multiple DU numbers under one login, making it a powerful hub for family or corporate account management.

Method 4: Online Account Portal — Ideal for Desktop and Laptop Users

If you prefer managing your mobile account on a larger screen or need to perform more detailed account administration tasks, the DU MyAccount web portal is an excellent option. This online platform gives you all the functionality of the mobile app in a desktop browser environment.

How to Access the DU Online Portal

To use the online account portal:

1. Open any web browser on your computer, tablet, or smartphone.
2. Navigate to DU’s official website.
3. Click on the “Login” or “My Account” button, typically located in the top-right corner of the homepage.
4. Select your customer category — either “Consumer” (for individual users) or “Business” (for corporate accounts).
5. Enter your registered email address and password. If this is your first time logging in, select “Register Here” and follow the on-screen prompts to create your account using your DU mobile number.
6. Once logged in, navigate to the “Usage Details” or “Balance” section.

The portal provides a detailed breakdown of your data consumption, call minutes used, SMS sent, and current credit — all within a clean, easy-to-read dashboard. Postpaid users can also access their complete billing history, download invoices, and set up automatic payment methods through the portal.

Benefits of the Online Portal

The web portal is particularly useful for users who:

• Prefer a larger screen for reviewing detailed usage breakdowns
• Need to download billing statements for expense reports or work reimbursements
• Want to manage multiple DU numbers under a single corporate login
• Are currently connected to Wi-Fi and do not want to use mobile data for app navigation
• Need to troubleshoot billing discrepancies with a detailed usage log

Method 5: Calling Customer Care — Human Assistance for Complex Queries

While USSD codes and the app handle most balance inquiries efficiently, there are situations where speaking directly to a DU customer service representative is the most practical solution — particularly if you are experiencing unexpected deductions, your USSD code is not working, or you need to escalate a billing dispute.

Contacting DU Customer Care

Dial 155 from your DU SIM card to reach DU’s customer support line. The call is free of charge when made from a DU number. Upon connecting, you will be greeted by an automated interactive voice response (IVR) system that guides you through a menu of options. For balance inquiries, follow the IVR prompts to the account or balance section, and the system will read out your current balance automatically — no need to speak to a human agent for straightforward balance checks.

If your query is more complex — such as an unrecognized charge, a failed top-up, or a plan migration issue — select the option to speak with a live customer service representative. Support agents are available across multiple languages, which is particularly helpful given the multicultural nature of the UAE’s population.

DU Self-Service Kiosks

DU also operates self-service machines at various locations across the UAE, including malls, business centers, and DU retail stores. These kiosks allow you to check your balance, top up credit, manage your plan, and even purchase new SIM cards. To check your balance at a kiosk, insert your DU SIM card into the designated slot, select the “Balance Inquiry” option, and the machine will display your current credit and data details on screen.

Method 6: Balance Alerts and Notifications — Proactive Monitoring

One of the most underused but highly practical features available to DU subscribers is the automatic balance alert system. Rather than reactively checking your balance after it runs low, setting up alerts allows DU to notify you proactively when predefined thresholds are reached.

Setting Up SMS Alerts

Through the DU mobile app or online portal, you can configure SMS notifications to be sent to your phone when your data consumption reaches certain percentage milestones — typically at 80% and 100% of your plan’s data allocation. These alerts are sent directly to your messaging inbox and are available to both prepaid and postpaid users.

For postpaid users, receiving a warning when approaching 100% of the monthly data limit is especially valuable, as exceeding the plan’s data cap typically triggers per-MB pay-as-you-go charges that can significantly inflate the monthly bill.

Post-Call Notifications

Some DU prepaid plans include post-call notifications, which automatically send you a brief SMS after each call detailing the cost of the call and your remaining credit balance. This real-time deduction tracking eliminates the need to manually use the du sim balance check code after every call, as the information arrives automatically.

Checking DU Balance While Roaming

UAE residents who travel internationally face a unique challenge: standard USSD codes may not function reliably while roaming on foreign networks. This is a well-documented limitation of the USSD protocol, which depends on the local GSM network infrastructure and may not be supported or forwarded correctly by international roaming partners.

Best Methods for Balance Checks While Abroad

Use the DU App over Wi-Fi: The most reliable way to check your DU balance while traveling internationally is through the DU mobile app connected to Wi-Fi. Since the app communicates over the internet rather than the cellular USSD channel, it works from anywhere in the world as long as you have a Wi-Fi connection.

Access the Online Portal: Similarly, logging into your DU account through the web portal from any internet-connected device gives you full access to your balance and usage data regardless of your physical location.

Contact Customer Care via Call or Chat: If the app is unavailable, you can reach DU’s customer support team via the online chat feature on their website — accessible from any device with internet.

Enable Data Roaming Alerts: Before traveling, configure data roaming alerts in the DU app. These will notify you as you consume data internationally, helping you avoid unexpected roaming charges even when USSD-based checks are unavailable.

Check Roaming Packages: DU offers specific international roaming data bundles that can be activated before or during your trip. The DU app shows the details and remaining allowance of these bundles clearly, which is the best du sim balance check code alternative when abroad.

How to Recharge Your DU SIM Balance

Knowing how to check your balance is only half the equation — knowing how to top it up when it runs low is equally essential. DU offers a variety of recharge methods designed to accommodate the diverse preferences and circumstances of its customer base.

Online Quick Recharge

DU’s website features a “Quick Recharge” function that allows anyone — even without a registered account — to top up a DU prepaid SIM. The process involves entering the mobile number to be recharged, selecting the desired amount, and completing payment via credit or debit card. The recharge is applied almost instantly and no login is required.

In-App Recharge

Registered DU app users can top up their own account or any other DU number directly through the app’s recharge section. Payment methods include credit cards, debit cards, Apple Pay, Google Pay, and other digital wallet options supported in the UAE.

Physical Recharge Vouchers and E-Vouchers

DU prepaid top-up cards are widely available at supermarkets, petrol stations, convenience stores, and pharmacies throughout the UAE. To redeem a physical card, scratch off the silver coating on the back to reveal a 16-digit PIN code, then dial the appropriate redemption code followed by the PIN to credit your account.

E-vouchers work the same way but are purchased and received digitally — through retail apps, online platforms, or messaging services — eliminating the need to visit a physical store.

Credit Transfer Between DU Users

DU offers a peer-to-peer credit transfer service called One2One that allows one DU prepaid user to transfer balance to another DU user. This is particularly useful in emergencies when one person’s credit runs out and a friend or family member can share some of their balance in real time.

Automatic Top-Up (Auto Recharge)

DU’s Auto Recharge feature, configurable through the app or online portal, automatically refills your prepaid balance when it falls below a minimum threshold you specify. This is the most hands-off approach to balance management — once set up, your account self-maintains, and service interruptions become a thing of the past.

Comprehensive Table: All DU USSD Codes and SMS Keywords

Troubleshooting: When Your DU Balance Check Is Not Working

Even the most reliable methods occasionally hit a snag. If you encounter issues using the du sim balance check code or any other balance inquiry method, the following troubleshooting steps should resolve most common problems.

USSD Code Not Responding

Check Your Signal: USSD codes require a minimum cellular signal to function. If you are in an underground area, basement, or remote location, try moving to a spot with better reception. Even a single bar of signal is usually sufficient for USSD to work.

Toggle Airplane Mode: Turn Airplane Mode on for ten seconds, then off again. This forces your phone to reconnect to the nearest DU tower and refresh the network connection, which often resolves USSD timeouts.

Verify You Are Dialing the Correct Code: Ensure you are typing *135# exactly as written, including the asterisk (*) at the beginning and the hash (#) at the end. Any variation will result in an error.

Check for SIM Suspension: If you have not recharged your DU prepaid SIM in over 90 days, the SIM may have entered a suspended state, during which some services — including USSD — may be restricted. Contact DU customer care at 155 to inquire about reactivation.

Dual-SIM Conflict: On dual-SIM devices, ensure the USSD call is being made through the DU SIM specifically. If your device uses another SIM as the default calling line, the USSD code will fail because it is being sent through a different carrier’s network.

DU App Login Issues

Update the App: An outdated version of the DU app may have bugs that cause login failures or display errors. Check the App Store or Google Play for any available updates and install them.

Clear App Cache (Android): Go to Settings → Apps → DU → Storage → Clear Cache. This removes temporary files that sometimes corrupt the app’s normal operation.

OTP Not Received: If the one-time password for login is not arriving via SMS, ensure your DU SIM has adequate signal. Also check that you are entering the correct mobile number associated with your DU account. If issues persist, contact customer care at 155.

Use the Web Portal Instead: If the app is persistently unresponsive, switch to the DU online account portal as a temporary alternative — it provides the same balance information without requiring the app to function.

SMS Balance Check Not Receiving a Reply

Confirm the Recipient Number: Double-check that you are sending your message to 1355, not to a different number. A common mistake is transposing digits.

Check for Message Sending Errors: Ensure your SMS has actually been sent (look for the sent checkmark in your messaging app). If the message shows a failure, try again after toggling Airplane Mode.

SIM May Be in Roaming Restriction: If you are traveling and your DU SIM has certain roaming restrictions applied, SMS services to short codes may not work. Use the DU app on Wi-Fi instead.

Tips for Smart DU Balance Management in the UAE

Simply knowing how to perform a balance check is one thing; actively managing your account to maximize value is another. The following practical tips can help you stretch your DU credit further and avoid the frustration of unexpected disconnections.

Set Low Balance Alerts

Use the DU app to configure automatic alerts that notify you via SMS when your prepaid credit falls below a specific amount — say, 10 AED. This gives you advance warning to recharge before your service is affected, rather than discovering a zero balance mid-call.

Monitor Data Expiry Dates

Many DU data bundles have validity periods tied to specific calendar dates rather than usage amounts. A weekly 5GB bundle might expire after seven days regardless of whether you have used all 5GB. Keeping track of expiry dates — visible in the DU app under the Balance or Usage section — prevents you from losing unredeemed data.

Use Wi-Fi Whenever Possible

A straightforward but highly effective way to preserve your mobile data balance is to connect to Wi-Fi at home, work, hotels, or cafes whenever available. Use mobile data only when Wi-Fi is not accessible, and disable mobile data for apps that run in the background unnecessarily.

Activate Auto-Renewal for Bundles

If you rely on a specific data bundle every week or month, enabling auto-renewal through the DU app ensures your bundle activates immediately upon expiry, eliminating any gap in connectivity. You can always cancel auto-renewal later if your needs change.

Review Usage Patterns Monthly

The DU app’s usage history section shows your data, call, and SMS consumption over time. Reviewing this monthly helps you identify patterns — for example, if you consistently use more than your plan allows, it may be time to upgrade to a larger package; if you consistently have leftover data, you might be able to save money by switching to a smaller plan.

Know Your Out-of-Credit Options

DU offers emergency credit services for prepaid users who have run out of balance and need to make an urgent call. These services typically add a small pre-agreed credit amount to your account that is deducted from your next top-up. Speak to customer care at 155 or check the DU app for any emergency credit options available on your specific plan.

DU Balance Check for Tourist SIM Users

Tourists visiting the UAE and purchasing a DU tourist SIM at the airport or any DU retail outlet have slightly different requirements. Tourist SIMs are typically prepaid and come with a pre-loaded data allowance — commonly ranging from 1GB to 10GB depending on the package purchased.

The same du sim balance check code (*135#) works perfectly on tourist SIMs. Simply dial the code from your tourist SIM, and the flash message will show your remaining data, credit, and the package expiry date — usually tied to your intended length of stay.

For tourists staying longer than originally planned, the DU app offers an easy way to purchase additional data bundles without visiting a physical store. Alternatively, the online quick recharge tool allows anyone to top up a DU tourist SIM using an international credit card.

Tourist SIM users should be particularly vigilant about monitoring their data balance since these plans typically have fixed allowances without automatic renewal. Once the data is exhausted and no top-up is added, the SIM will either stop providing data connectivity or switch to a much slower pay-as-you-go rate, depending on the package terms.

DU Balance Check for Business Users

Corporate DU customers managing multiple SIM cards under a business account have access to additional balance monitoring capabilities beyond what individual consumer accounts offer.

Business Account Portal

DU’s business account portal provides a centralized dashboard where company administrators can view the balance and usage data for every SIM card under the corporate account simultaneously. This eliminates the need for individual employees to check their own balances separately and allows the company’s IT or telecom manager to monitor consumption across the organization in real time.

Bulk Usage Reports

Business accounts can generate detailed monthly usage reports in downloadable formats, which are useful for internal cost allocation, expense reporting, and identifying employees who may be consistently exceeding their data limits.

Dedicated Business Support

DU provides a dedicated business customer support line and account management service for corporate clients, offering faster resolution times and a more personalized experience compared to the general consumer support line at 155.

Frequently Asked Questions

How do I check my DU prepaid balance?

Dial *135# from your DU SIM card and press the call button. A pop-up message will appear within seconds displaying your remaining credit, data, and validity period. This is the standard du sim balance check code for prepaid users and it is completely free to use.

Can I check my DU balance without any credit?

Yes. The *135# USSD method works even when your account balance is at zero. The balance check service is provided free of charge by DU, and no credit is deducted for using it. You can also use the DU app on Wi-Fi, which requires no credit at all.

What is the DU balance check code for data only?

To check your remaining internet data specifically, dial *102# from your DU SIM. This will display a pop-up notification showing your remaining MB or GB and the expiry date of your current data bundle. You can also send BAL to 1355 via SMS for a text-based response that includes data balance details.

How do I check my DU postpaid balance?

Postpaid DU users can dial *135# and navigate the on-screen menu to the usage or account section. Alternatively, use the DU app’s dashboard for a real-time view of unbilled usage and current cycle consumption. The online portal at DU’s website provides the most detailed billing and usage breakdown for postpaid accounts.

Is checking DU balance free?

Yes. All official DU balance check methods — including the USSD *135# code, the SMS service to 1355, the DU mobile app, and the online account portal — are provided free of charge. No credit is deducted when you inquire about your balance through any of these channels.

Why is my USSD code not working?

Common causes include weak cellular signal, SIM suspension due to inactivity for over 90 days, or a dual-SIM conflict where the code is being sent through the wrong SIM. Try toggling Airplane Mode, moving to a better signal area, or verifying that your DU SIM is the active calling SIM on your device. If problems persist, contact DU customer care by dialing 155.

How do I check my DU balance while traveling abroad?

USSD codes may not function reliably on international roaming networks. The best alternatives are using the DU mobile app over Wi-Fi or accessing the DU online account portal from any internet-connected browser. Both provide complete account information regardless of your physical location.

Can I check my DU number using a USSD code?

Yes. Dial *116# from your DU SIM card, and your mobile number will appear on screen immediately. This service is free and requires no credit or internet connection, making it useful if you have just received a new SIM and need to know its number.

How often should I check my DU balance?

For prepaid users, checking your balance every two to three days is a reasonable practice, especially if you use significant amounts of data or make frequent calls. Setting up automatic low-balance alerts through the DU app is even more convenient, as it eliminates the need for manual checks by sending notifications to your phone when thresholds are reached.

What happens when my DU prepaid credit runs out?

When your DU prepaid credit reaches zero, outgoing calls and data usage will stop. Incoming calls may still be received for a limited period depending on your plan terms. To restore full service, simply recharge your account using any of the top-up methods described in this guide. DU may also offer emergency credit for eligible prepaid accounts.
