How to Check DU Balance & Recharge Online: Easy Steps (2026)

Your call cuts off right in the middle of an important conversation. You try to dial back, but nothing happens. Then it hits you that your Du balance has run out. If you have been in the UAE for any amount of time, this situation is very familiar. Du (Emirates Integrated Telecommunications Company) has been serving UAE residents since 2006 and now covers over 8 million subscribers across the country. But a lot of people still do not know the quickest ways to check their remaining credit, data, or bill status.

The good news is that Du gives you multiple free methods to check your balance. You do not need to visit a store or call customer care every time. Whether you are on a prepaid SIM, a postpaid plan, or a tourist SIM picked up at Dubai Airport, the same set of tools works for you. This guide covers every working method in 2026, including what to do when the usual codes stop working.

Before checking your balance, you need to first find out how to check your Du number, which is a quick separate step you can sort out in seconds.

How to Check Du Prepaid Balance?

Prepaid users want speed. No menus, no waiting, just the number on screen. Here are the three methods that work every time.

Method 1: USSD Code (Fastest, No Internet Needed)

This is the method most Du users rely on daily. It works on GSM signal alone, no data required.

1.   Open your phone dialer.
2.   Dial *135# and press the Call button.
3.   A menu appears on screen. Select 1 for Account Information.
4.   Select 1 again for Balance Inquiry.
5.   Your remaining credit in AED appears instantly.

Method 2: Check Du Prepaid Balance via SMS

If the USSD menu is slow or unresponsive, SMS is the most reliable offline backup.

1. Open your Messages app.
2. Type “BAL” into a new message.
3. Send it to 1355.
4. You will receive an SMS showing your remaining credit and plan validity.

Method 3: Du App (Most Detailed View)

The Du app gives you a full picture: remaining credit, active bundles, data usage, and plan renewal dates on one screen.

1. Download the Du App from the Google Play Store or Apple App Store.
2. Open the app and log in with your Du mobile number or through UAE Pass.
3. Your credit balance will appear on the home screen under “Account Summary.”
4. Tap “Usage” for a breakdown of the remaining minutes, SMS, and data.

How to Check Du Postpaid Balance?

Postpaid works differently. You are not spending credit; you are building a bill. What matters here is how much you have used this month and what your current outstanding amount is before the payment date.

Method 1: SMS for Postpaid Users

1. Open your Messages app.
2. Type rewards and send to 1355.
3. You will receive your current usage, remaining data allowance, and remaining minutes.

To see all your active subscriptions and add-ons, send “List” to 9000. This tells you exactly which bundles are running and when they renew, which is useful if you suspect a subscription is quietly auto-renewing.

Method 2: Du App for Postpaid

1. Open the Du app and log in.
2. Tap “My Bills” or “Account Summary” from the home screen.
3. You will see your outstanding bill amount, billing cycle dates, and data or call usage so far this month.
4. Tap “Usage” for a full breakdown by category.

Method 3: Du Website

1. Go to the official Du page and click Login at the top right.
2. Choose “Consumer” or “Business” based on your account type.
3. Enter your credentials and click Login.
4. Go to My Account > Usage and Bills.
5. Your bill details, payment Due date, and full usage history are displayed here.

How to Check Du Data Balance?

Most Du users search specifically for their remaining internet data, not just credit. Here are the dedicated methods for data balance only.

USSD Code for Du Data Balance

Dial *102# from your phone dialer. A pop-up shows your remaining data (in MB or GB), bundle name, and expiry date. No internet is needed.

Alternatively, dial *135# and navigate to the Data or Usage option from the on-screen menu.

SMS for Du Data Balance

Send ‘BAL’ to 1355. The reply SMS shows your remaining data in MB or GB, your active bundle name, and the exact expiry date of your plan.

Du App for Data Balance

Open the Du app and tap ‘Usage.’ You will see two things:

•       Main pack balance shows GB remaining from your primary plan.
•       Add-on balance shown as a separate line if you purchased any extra data boosters.

The app also shows your bundle renewal date, which is the most important figure to watch if you want to avoid being switched to pay-as-you-go rates mid-month.

Du MyData Website (Browser Option)

Open the official Du MyData page in any browser on your phone or laptop. Log in with your Du number. This portal shows a full breakdown of your data usage including add-ons, roaming data consumed, and renewal cycles. It works on WiFi alone, so even if your SIM data is empty, you can check it from any connected device.

All Du USSD Codes and SMS Shortcuts

How to Check Du Balance While Roaming Abroad?

This is the section most guides skip. When you are outside the UAE, the usual USSD codes often stop working because foreign networks do not always pass those requests through. Here is what actually works:

• Du App on WiFi: Open the app connected to hotel or cafe WiFi. Your balance and data usage will show normally.
• Du My Data Page: Works from any browser on any WiFi connection. Go to the Du My Data webpage, log in, and check everything.
• Call Du from abroad: Dial +971 4 390 5555 for customer care. This is the international number that works outside the UAE.
• Automatic SMS alerts: Du sends SMS notifications when you hit 70%, 80%, and 100% of your roaming data bundle. These come automatically without you doing anything.

If you travel regularly and carry a second SIM from Etisalat (e&), the process to check your Etisalat balance and recharge online follows a similar pattern with different codes.

How to Recharge Your Du Balance?

If your balance runs out, here are the quickest ways to top up without heading to a store:

• Du App: Tap “Recharge,” enter your card details, and the top-up will reflect instantly.
• Du Website: Log in to My Account and pay by debit or credit card.
• Physical recharge cards: Available at Carrefour, LuLu hypermarkets, petrol stations, and most convenience stores across the UAE.
• Emergency credit (*108#): When your balance hits zero, dial *108# and Du will advance you a small amount to keep you connected. The amount is deDucted automatically from your next recharge.

LuLu hypermarkets are one of the most convenient places to find Du recharge cards across UAE. You can also check your LuLu card balance from the same visit if you use their loyalty card for shopping.

Du Balance Check Not Working: Fixes That Actually Help

Frequently Asked Questions

What is the Du balance check code?

The main code is *135#. Dial it from your Du number, select Account Information, then Balance Inquiry. For data balance specifically, dial *102# for a direct pop-up without going through any menu.

How do I check Du data balance without internet?

Dial *102# or *135# from your phone dialer. Both work on GSM signal only, no data required. You can also send “BAL” to 1355 by SMS, which also works without any internet connection.

How do I check my Du postpaid bill?

Send “rewards” to 1355 for a quick SMS summary of your usage and outstanding amount. For the full bill breakdown with payment Due date, log into the Du app and go to My Bills.

Can I check Du balance while outside the UAE?

Yes, but USSD codes are unreliable on foreign networks. Open the Du app on WiFi or visit MyData page from any browser. For urgent account help, call +971 4 390 5555.

Is Du balance check free?

Yes. Checking your balance via *135#, *102#, SMS to 1355, the Du app, or the website is completely free inside the UAE. Standard roaming charges may apply if you use SMS or call-based methods from outside the country.

How do I transfer Du balance to another number?

Dial *121*[recipient number]*[amount in AED]# from your Du prepaid SIM. For example, to send AED 5 to 0551234567, dial *121*0551234567*5#. This works for Du-to-Du and Du-to-other-UAE-network transfers.

How do I find my Du number?

Dial *116# from your Du SIM. Your number displays on screen immediately. No need to call anyone or open any app.

What happens when my Du prepaid balance hits zero?

Outgoing calls, SMS, and data stop immediately. Incoming calls may still work depending on your plan. Your quickest option is to dial *108# for Du emergency credit, or top up through the Du app, website, or a physical recharge card.

Final Thoughts

For everyday use dialing *135# and *102# is the fastest and free way to check your remaining Du balance offline. If you need complete details like billing cycles or active add-on statuses, the official Du application provides a full account overview within seconds of logging in.

It is highly recommended to monitor your auto renewal dates regularly rather than just tracking data usage so you never get surprised by unexpected charges. You can quickly audit all active services by sending the word ‘List’ to 9000 and always ensure that your Emirates ID is up-to-date to prevent any future account verification delays.
