Staying on top of your du data balance keeps you from slowdowns or out-of-bundle charges. This guide shows every reliable way to Check Data Balance in du—app, USSD, SMS, web self-care, and by phone plus how to read the numbers (daily vs pooled data), fix common errors, and what changes when you’re roaming or on a shared plan.

Quick answer (fastest three)
- du app (recommended): Open the app → your line’s dashboard shows remaining data and expiry/renewal.
- USSD: Dial *135# → choose Balance/Usage → Data. Works without mobile data.
- SMS: Send BAL or Balance to 1355 → you’ll get your remaining data and validity by SMS.
Data Balance Check Methods (step-by-step)
1) Check via du app (most complete)
- Open the du app and sign in.
- Tap your mobile line. The home card shows data left and days to renew/expire.
- Tap Usage/Balance to see add-ons, shared bucket usage, and renewal status.
Good to know: The app separates daily allowances (e.g., 1GB/day) from pooled buckets (e.g., 28GB/28 days). Look for the wording under the usage bar.
2) USSD (works without data)
- Open the dialer and call *135#.
- From the menu, pick Balance/Usage → Data.
- You’ll see a pop-up (and often an SMS) with remaining MB/GB and sometimes validity.
Tip: On some plans, the menu wording varies slightly. Always choose the option labeled Usage, Balance, or My account.
3) SMS (quick + offline)
- Create a new message to 1355.
- Type BAL or Balance.
- You’ll receive an SMS with data left and often the expiry/renewal date.
Notes: SMS requests are generally free on du mobile lines. If you’re roaming and can’t send app data, this is usually the fastest fallback.
4) Web self-care (mobile site)
- On your phone, open the du self-care/usage site and log in.
- Go to Usage/Balance for a full breakdown (main bucket, add-ons, and renewal).
5) By phone (IVR or an agent)
- Self-service IVR (balance): Call 135 and follow the prompts to balance/usage.
- Customer care (human): Call 155 in the UAE (use the international care number when abroad). Agents can read out your balance and help with plan issues.
6) Chat support (app / WhatsApp)
- In-app chat can confirm your usage after security verification.
- WhatsApp “du chatbot” helps with support flows; for account-specific balances you’ll typically be directed to log in via app or portal for privacy.
How to read what you see (and why numbers sometimes differ)
Daily allowance vs pooled data
- Daily allowance packs (e.g., 1GB/day for 28 days) reset each day. Your app/USSD may show today’s balance only; unused daily data doesn’t roll over.
- Pooled/bucket packs (e.g., 28GB/28 days) draw down from one pot and show total remaining GB plus days left.
Add-ons and shared bundles
- If you add an extra data booster, you’ll see separate lines (e.g., “Main pack” + “Add-on”).
- Shared/family bundles split usage across lines; your app usually shows your line’s share plus the bundle total.
Postpaid vs prepaid
- Both can check via app, USSD, and SMS. On some postpaid plans, USSD may show a summary while the app shows detailed usage and bill-cycle renewal. “Prepaid Package – Du“
Alerts you’ll get
- du sends usage alerts when you approach and reach your allowance. The exact percentages can vary by product (commonly ~70–85% and 100%). Treat these as heads-up, not real-time meters; there can be short delays.
Troubleshooting & edge cases
USSD says “service unavailable” or shows no data
- Try again where signal is stronger.
- If you’re on Wi-Fi calling only, briefly disable Wi-Fi to place the USSD call.
- Dual-SIM? Ensure the du line is the active calling line.
App shows a different number than USSD/SMS
- Allow a few minutes; systems sync on a schedule.
- Check if an add-on or shared bundle was just activated.
- Force-refresh the app (pull to refresh or sign out/in) and re-dial *135#.
eSIM or device switch
- Reinstall/sign in to the du app and re-verify your number.
- For IVR access, use the du SIM/line to call so the system recognizes your account.
While roaming
- The app and self-care site still work over data/Wi-Fi.
- SMS to 1355 and *135# often work (depends on visited network). If blocked, use the app over Wi-Fi.
- Expect roaming-specific alerts (e.g., when you hit certain percentages).
Corporate / company-paid lines
- Some companies restrict add-ons or hide certain breakdowns. If the app looks limited, contact your company admin or call 155.
Pro Tip: Save a text shortcut “bal→1355” and favorite *135# in your dialer. When roaming or low on data, these offline checks are the quickest safety net.
Fees, language & small print
- Balance checks (app/USSD/SMS) are typically free on du within the UAE. Standard SMS/roaming rules apply abroad.
- You can switch Arabic/English in the app and some USSD menus.
- Auto-renew: Bucket plans may auto-renew; daily-allowance packs reset daily within the validity. Always check the renewal toggle/status in the app before the cycle ends.
Related checks
- Minutes/SMS balance: The same methods (app, *135#, 135 IVR) show other allowances.
- Expiry/renewal date: Visible under your plan card in the app or in the Usage/Balance section.
- Top up or buy add-ons: Use the app’s Recharge or Add-ons. SMS activation codes for bundles still work on many plans.
FAQs
What’s the fastest way to check du data balance?
Use the du app or dial *135#. SMS BAL to 1355 is the best offline fallback.
Why do I get different numbers across methods?
Short synchronization lags, add-on activations, or shared bundle allocations can create small, temporary differences. Refresh and re-check after a few minutes.
Can I see the exact expiry or renewal date?
Yes—on the app’s plan card or Usage/Balance page. USSD/SMS sometimes include validity in the reply.
Do balance checks cost anything?
In the UAE, these checks are generally free. While roaming, standard SMS/USSD availability and charges depend on the visited network.
Can WhatsApp give me my balance?
The du chatbot can route requests, but for account-specific balances you’ll usually be asked to log in (app or portal) for security.
