What to do once you know your du number
Finding your number is only the first step, so here are a few related checks that I could confirm from published guides. According to the Gulf News guide to checking prepaid balance, you can check your balance by dialling *135# or texting balance to 1335, and you can download the du app, create an account with your mobile number and add credit with a debit or credit card.
Reaching du support
Bayut’s du balance transfer guide gives *177# for the IVR menu and 800-155 for a representative. The post above mentions dialling 155 from a du phone, so if one does not connect, try the other. Have your Emirates ID ready, since the agent may ask you to verify who you are.
Useful related facts from the same guide
- Credit can be sent from one du number to another with the *121# codes, and the guide gives a minimum of AED 2 and a maximum of AED 200 per transaction, though you should confirm current limits with du.
- International credit transfers are described as a text SEND to 1700, with a List text showing supported countries.
Why you should save your number somewhere safe
- Many UAE services, such as banking apps, delivery apps and government portals, send one-time passwords to your registered mobile number.
- If you change your number, you may need to update it on those services. Keep the old SIM active until you have done so.
- If you cannot recall which number is registered with your Emirates ID or bank, check with the relevant provider rather than guessing.
If none of the methods in the post work, for example because the SIM is not activated or the phone has no signal, contact du support through the numbers above, and see the Bayut’s du balance transfer guide for further details on support options.
Quick comparison of support routes
| Route | What it is useful for |
|---|---|
| *135# or text balance to 1335 | Checking prepaid balance |
| du app | Account and top-up, after signing up with your number |
| *177# or 800-155 | Speaking to du |
Because published guides do not always agree on support numbers and codes, treat the table as a guide and use the du app or your SIM documents to confirm which route works on your line. If you buy a new SIM, note the number straight away so you can give it to your bank and employer.
