Call forwarding guides
Everything about UK call diverts that is the same whichever network you are on: what each code does, what forwarding costs, and why the code you typed was rejected. Network-specific quirks live on the individual network pages.
Call forwarding in the UK: how to divert mobile calls
How UK call forwarding and call divert work on mobiles. Set up unanswered-call forwarding, check what is active, avoid voicemail, and undo it safely.
How to cancel call forwarding: ##61#, ##004# and ##002#
Which code cancels call forwarding on a UK mobile? Use ##61# for unanswered calls, ##004# for conditional diverts, and ##002# to clear everything.
How to stop calls going to voicemail (UK)
Voicemail is the destination for calls you do not answer, not a feature you switch off. How to change where unanswered calls go on any UK network, and how to put it back.
UK call divert codes: the full GSM reference
Every UK call divert code in one table. What ##61# does, how to set and cancel diverts for no answer, busy, unreachable and all calls, and how to check what is set.
*61 vs **61: what's the difference?
Both *61*number# and **61*number# set a divert for unanswered calls. The difference is registration: the double-asterisk form stores the destination, which is why it survives a reboot.
Does call forwarding cost money in the UK?
Setting a divert is free. The forwarded call itself is billed to you like a call you made to the destination, so it can use your inclusive minutes. What that means in practice.
Conditional call forwarding explained
Conditional call forwarding redirects a call only when a condition is met — no answer, busy, or unreachable. How it differs from unconditional forwarding, and why it matters.
Call forwarding while abroad and roaming
Your call divert stays on your line while you are roaming, but who pays for the forwarded leg changes. What to check before you travel, and what to do about it.
How to check what call divert is set on your line
Dial *#61# to see what happens to your unanswered calls. How to interrogate every divert condition, read the reply, and work out what your line is actually doing.
Why won't my call forwarding code work?
Call divert code rejected, or set but not working? The handset, network and plan reasons a forwarding code fails, and what to try instead on iPhone and Android.
Missed call statistics UK: what's actually evidenced
The figures this industry quotes, with their sources shown — including the ones that turn out to have no source at all.
Guides for your network
The dial codes are the same everywhere. What differs is which ones each network accepts, what its handset menus are called, and what it does to your settings after a SIM swap.
