For a small transfer to someone you send credit to often, the direct code is fine. For a larger one-off amount, Du’s guided menu is worth the extra step — it shows a confirmation screen with the recipient number and amount before anything is sent, catching typos the direct code wouldn’t.
Quick answer
Dial *121*[recipient number]*[amount]# — for example, *121*0551234567*10# sends AED 10. Press 1 to confirm when prompted.
Direct code vs. guided menu
The direct code is faster once you’re confident in the number — but for a larger or unfamiliar transfer, dial *121# or *135# instead and follow the step-by-step prompts, which separate entering the number from entering the amount and show both back to you before the final confirm.
The confirmation step matters
Either way, a confirmation screen appears showing the recipient number and amount — press 1 to confirm or 2 to cancel. Once confirmed, the transfer is instant and cannot be reversed, so this is the moment to actually verify the number rather than pressing 1 out of habit.
Restrictions
Works between Du prepaid numbers only, not to Etisalat or postpaid accounts.

Troubleshooting
"Insufficient balance" error
You need enough balance for the transfer amount PLUS the service fee, and must maintain a minimum balance after the transfer. Reduce the transfer amount or recharge first.
"Recipient not eligible" error
The recipient must be on an active Du prepaid account. Transfers to postpaid, business lines, or numbers on other networks will fail. Verify the number and ask the recipient to confirm they're on Du prepaid.

Can I cancel after confirming?
No, once confirmed the transfer is instant and irreversible — double-check the recipient number before pressing confirm.
Should I use the direct code or the guided menu?
The guided menu (*121# or *135#) is safer for larger or unfamiliar transfers since it shows a confirmation step; the direct code is faster for regular small transfers.
