A “Flash Message” will appear on your screen showing your current credit balance. This method is free of charge and works even if you have zero balance.

How to Check Du Data Balance Expiry Date (Prepaid & Postpaid)

Knowing your remaining data is one thing, but knowing when it expires is crucial to avoid sudden disconnections. Whether you are using a daily, weekly, or monthly plan, follow these steps to check your validity:

1. Check Expiry via USSD Code

For a quick check on your data validity, dial *102#. A pop-up notification will appear on your screen showing:

• Your total remaining data (MB/GB).
• The exact date and time when your current data plan will expire.

2. Check Expiry for Postpaid Users

If you are on a Du postpaid plan, your data resets every billing cycle. To check your usage and the remaining days in your cycle:

• Dial *177# from your Du mobile.
• Or, send an SMS with “rewards” to 1233. You will receive a summary of your consumed data and the next renewal date.

Managing Special Du Data Offers (2 AED and 30 AED Plans)

Many tourists and residents in Dubai use budget-friendly plans like the 2 AED Daily Data or the 30 AED Monthly Data packages. Here is how you can manage them:

• Du 2 AED Daily Data: To check your usage for the daily 2 dirham plan, dial *055# and follow the on-screen instructions under “My Offers.”
• Du 30 AED Data Package: This is a popular social data plan. To check your remaining MBs for this specific package, dial *135# and select the ‘Data’ option to see your active subscriptions.

Traveler Tip: If you are a visitor using the Du Tourist SIM, you might have received free 1GB of data. To check this specific “Welcome Data,” simply dial *135# or use the official Du App for a visual breakdown of your free MBs.

Alternative Ways to Track Du Usage: App & Online Portal

If you are unable to check your balance via USSD codes or SMS, Du provides digital alternatives that are highly reliable for residents and long-term tourists.

1. Using the “My Du” Mobile App

The Du App is the most comprehensive tool for managing your SIM. It is available on both the Apple App Store and Google Play Store.

• Real-Time Tracking: View your data, minutes, and credit balance on a visual dashboard.
• Direct Recharge: You can top up your balance or buy new data packs directly using a credit card or recharge voucher.
• Auto-Renewal: Check if your data plans are set to auto-renew to avoid unexpected charges.

2. Checking Du Balance Online (Web Portal)

If you don’t want to download an app, you can use the Du MyAccount portal on their official website.

• Log in with your mobile number.
• You will receive a one-time password (OTP) for security.
• Once logged in, you can manage multiple Du numbers under one account, which is perfect if you have a separate data SIM for your iPad or router.

Why is my Du Balance Check Code Not Working?

Sometimes, users face issues while dialing *135# or *102#. Here are a few quick fixes:

• Network Signal: Ensure you have at least 2 bars of signal. USSD codes require a stable GSM connection.
• SIM Expiry: In the UAE, if you do not recharge your SIM for over 90 days, it might go into a “Suspended” state.
• Flight Mode: Try toggling Flight Mode ON and OFF to refresh your network connection.

Final Conclusion

Managing your internet in Dubai is just as important as knowing your way around the city. Now that you know how to keep your Du balance and data in check, you can explore the city without the fear of getting disconnected.
