du UAE Guide: Codes, Data, SIM and Home Internet

du is one of the UAE’s two mobile networks, run by Emirates Integrated Telecommunications Company (EITC). On a du line, *135# opens the self-service menu with your balance, *116# shows your own number and 155 reaches customer care. The du app covers the rest: live usage, bills, plan changes and eSIM.

Short codes do change. If one stops working, the du app shows the same balance, usage and plan details.

Balance, number and credit

One2One moves credit between du prepaid numbers only, so it cannot send credit to another network. Out of Credit lends AED 5 to prepaid lines at least three months old that use at least AED 10 a month, and takes it back with an AED 1 fee plus VAT from your next recharge.

Data packs, plans and call offers

Packs and prices change often, so check the du app or the *135# menu before you buy. Recurring packs keep renewing until you cancel them, which you can also do from the same menu.

SIM, eSIM and contracts

Residents register a du SIM with an Emirates ID, and visitors with a passport. Converting to an eSIM is free in the du app, while a du store charges AED 20 plus VAT. To leave a postpaid contract, first check its end date and any device instalments.

Home internet and Wi-Fi

To change your Wi-Fi password, connect to your home network and open the router page, usually 192.168.70.1 or 192.168.1.1, then sign in with the admin details on the router sticker.

Customer care

Call 155 within the UAE. du also offers help in the app and through its Noora chat assistant. Have your du number or account number ready, with your Emirates ID or passport details for verification.
