Your main credit is just one part of your account. Here is how to check other important balances.

How to Check Du Data Balance

Running out of data is a common problem. Use the *135# code and follow the on-screen menu. It will typically present an option like “Check Data” or “Manage Bundles.” Alternatively, the Du app provides a visual data usage meter, showing exactly how many GBs you have left.

How to Check International Minutes Balance

If you have an international calling plan, dial *135# and look for an option related to “International Minutes” or “Bundles” in the menu. This will show you how many minutes you have remaining for specific countries.

How to Check Your Du SIM Number

Forgot your own number? It happens. The simplest way is to dial *115*1#. Your Du mobile number will appear on the screen.

Managing Your Du Balance: Recharge and Transfer

Knowing your balance is the first step. The next is managing it.

How to Recharge Your Prepaid Line

When your balance is low, you can recharge using:

• Scratch Cards: Available at supermarkets, groceries, and Du stores.
• Du App/Website: Use a credit or debit card for an instant online recharge.
• Bank Apps: Most UAE banking apps have a “Telecom Recharge” feature.

How to Transfer Credit to Another Du Number

Need to help a friend? You can share your credit.

1. Dial *121*<recipient's number>*<amount>#.
2. For example, to send 10 AED, you would dial: *121*05xxxxxxxx*10#
3. Follow the on-screen prompts to confirm the transfer. A small fee applies for this service.

Paying Postpaid DU Balance:

Like prepaid customers, users with postpaid Du sims can also use the Du website and App to pay their monthly bills. The procedure to pay postpaid bills is almost the same on Du App and Du web portals. You’ll log in to your account, navigate to the payment tabs, and pay your postpaid balances through different online transaction options. 

Customers can also activate the auto-bill payment features on their account to ensure timely payments. This way, the postpaid amount will be automatically deducted from the user’s account every month. 

Other common ways to make postpaid bill payments are by either directly visiting a Du Branch or going to bank branches that are affiliated to receive the Du payments. 

Conclusion

Checking your Du balance should be a quick and painless process. For instant, offline checks, the USSD code *135# is your go-to tool. For a complete overview of your prepaid credit, postpaid bill, and data usage, the Du App is the most powerful and user-friendly option.
