du SIM Renewal Online 2026: Validity, Grace Period, Keeping Your Number
A du prepaid line has no separate "renewal" - every recharge resets the validity window. Let it lapse and the line slides into a short receive-only grace window, then the number is reclaimed and resold. Renewing online is simply a recharge in the du app or on du.ae before expiry; the app or *135# shows your remaining days.
How du validity actually works
Prepaid validity runs in cycles tied to recharges: each recharge opens a new window, and the app shows the exact end date for your line. Miss it and the sequence is predictable - outgoing services stop first, then incoming, then the number itself is released back into the pool.
There is no annual fee that "renews" a du SIM. The recharge is the renewal. Any figure you have read about renewal charges applies to other products (like contract lines), not the prepaid cycle.
Renewing online, step by step
Fastest is the du app with a saved card - under a minute. The du.ae recharge page works without the app, and *135# takes voucher codes from any supermarket. If the number matters but you rarely use it, put a small auto-renew pack on it: the app recharges the line each cycle so a bank-OTP number never quietly dies.
Abroad: recharge online before the window ends. A lapsed UAE number means dead OTPs for banking and government apps exactly when you need them most.
If the line already expired
Act within days, not weeks. Freshly expired lines are often recoverable with a recharge or a quick call to 155 / visit to a du shop - recovery odds drop sharply once the number is recycled and re-issued. If it is truly gone, it has been reassigned; take a new line and update your bank and government app numbers the same day.
Quick answers
How do I check my du SIM expiry date?
The du app shows the validity end date on the line's home screen, and the *135# menu reports it too. If the app shows "grace", recharge immediately - that state is receive-only.
What is the minimum recharge to keep a du SIM active?
The smallest recharge voucher on the menu resets validity. The live minimum for your line is shown in the app before you pay - that figure wins over any you read elsewhere.
My du SIM is barred - recharge or visit?
If it is a validity bar, a recharge restores it on the spot. If a recharge does not clear it, the bar is registration- or dispute-related - a du shop with your Emirates ID sorts it.
