- Save an SMS template BAL → 1355 for one-tap checks without data.

Understand your result for du balance check
Main balance vs wallets
Main balance: Your core prepaid credit for pay-as-you-go or out-of-bundle use.
Promo / bonus wallets: May appear as separate data/minutes that expire earlier than your plan.
Data types you might see
General data: Works on all sites.
App-specific/social data: Only for designated apps.
FUP / fair usage: Some plans slow speeds after a daily/monthly threshold—you’re not cut off, just throttled.
Renewal dates & cycles
Auto-renew bundles: Renew on the same day each cycle if you have enough balance.
Grace windows: Some add-ons allow a short grace to top up; otherwise, the add-on pauses.
VAT and amounts
Prices in AED include 5% VAT in the UAE; your app bill and SMS replies typically reflect VAT-inclusive figures.
Troubleshooting common issues
USSD not working?
Signal or barring: Move to better coverage; ensure voice/SMS isn’t barred. Restart the phone and try *135# again.
SMS reply delayed?
Queue or congestion: Keep the thread; avoid resending repeatedly. If nothing after 5–10 minutes, retry or switch to *135#.
App shows zero or odd usage
Sync delay: Pull-to-refresh and relaunch. Log out/in. If still wrong, chat support can check your line in real time.
Roaming checks abroad
App first: It’s the clearest way to see roaming bundle usage. If data is restricted, use SMS “BAL” to 1355 or call 155 (roaming charges may apply).
Pro Tip: In the du app, set usage alerts at 50%, 80%, and 100% and add a home-screen widget. This prevents accidental out-of-bundle data and keeps your monthly cost predictable.
FAQs on how to check du balance in UAE
How do I check du data balance without the internet?
Use *135# or send “BAL” to 1355. Both methods work without mobile data and show remaining data and main balance. If you prefer a call, dial 155 and use the menu to hear your balance.
What’s the difference between my main balance and add-on data?
Main balance is your prepaid credit for calls, SMS, and out-of-bundle usage. Add-on data is package-specific and may have its own allowance, validity, and app rules. When add-on data ends, usage can switch to main balance.
How can postpaid users check the amount due?
Open the du app → Bills to view your current charges, billing cycle, and due date. You can also call 155 to hear the amount due or request an itemized breakdown via the app.
Why do I get usage alerts at 50/80/100%?
These proactive notifications help you avoid overuse. They signal when you’ve consumed half, most, and all of your bundle so you can slow down, add data, or wait for renewal—great for budgeting and avoiding throttling.
