Initial network setup (How to Enable WiFi Calling Android)

Configuring call and voicemail features is normally done in phone settings or through dial codes — the UK APN Hub lists the latest ones for your plan.

Common network dial codes

UK networks all use the same standard GSM codes for call forwarding and voicemail:

Divert all calls: Dial **21*[number]# and press call.

Divert when busy: Dial **67*[number]# and press call.

Divert when no answer: Dial **61*[number]# and press call.

Cancel all diversions: Dial ##002# and press call.

Check voicemail: Hold down the 1 key or dial your voicemail number.
