ℹ️ About iD Mobile — Voicemail Not Working

iD Mobile operates on the Three MVNO. iD Mobile is sold exclusively through Currys/PC World. APN is simply "id" — one of the shortest in the UK.

Known Samsung Galaxy considerations: Wi-Fi Calling must be enabled in the iD Mobile app before it appears on your device. eSIM requires QR code from the app.

Restoring iD Mobile Voicemail on Samsung

Dial the iD Mobile voicemail number
Call 123 from your iD Mobile SIM. If the call connects and asks for a PIN, voicemail is working but the divert may need restoring. If the call fails, proceed to the next step.
Re-enable call divert for voicemail
Dial **61*123*11*30# from your Samsung phone dialler and press Call. This re-enables the voicemail divert for unanswered calls on iD Mobile.
Enable divert for busy and unreachable
Dial **67*123*11*30# (busy) and **62*123*11*30# (phone off/no signal). This restores voicemail when your Samsung is unavailable on iD Mobile.
Reset PIN if locked out
If voicemail asks for a PIN you do not know, call 7777 (from iD Mobile) to reset it. iD Mobile will verify your identity before resetting the voicemail PIN on your account.
Check voicemail via app
The iD Mobile app or Visual Voicemail feature on your Samsung may give direct access to messages without a PIN. Check your iD Mobile app for a voicemail or messages tab.
Check number format
If using codes, ensure the voicemail number is in full UK format. Some Samsung models require a + prefix: +44 followed by your own mobile number without the leading 0 instead of 0 or just 123.
Contact iD Mobile for provisioning
If voicemail has never worked or was recently lost after a plan change, call 7777 (from iD Mobile). iD Mobile may need to re-provision the voicemail service on your account.

Frequently Asked Questions

What is the iD Mobile voicemail number?

The iD Mobile voicemail access number is 123. Dial this from your iD Mobile SIM to check messages. If calling from abroad, dial the full international format: +44 followed by the number without the leading zero.

How do I set up voicemail on iD Mobile?

Dial 123 from your Samsung and follow the recorded prompts to set your PIN and record a personal greeting. If voicemail is not set up, callers will hear a default iD Mobile greeting. You only need to do this once.

Why has iD Mobile voicemail stopped working?

Voicemail on iD Mobile works via a call divert. If the divert was cleared — by a network reset, SIM swap, or firmware update — voicemail calls will ring indefinitely instead of going to the mailbox. Re-enable using dial code **61*123*11*30# on your Samsung.
