Answerphone by jypsygen http://www.flickr.com/photos/jypsygen/3461757736/sizes/l/For some reason, the iPhone 4, iPhone 4S and iPhone 5 (with the current or recent versions of iOS) have very few options for call diversion. Fortunately, it is possible to set up all the usual diverts using network codes from the keypad. To divert to voicemail, you need to know your <voicemail> number (see the section below).

The instructions below work regardless of phone operating system, so do work for Android
, BlackBerry and other devices. Those phones tend to provide these features in a more intuitive fashion, but if you can’t find the settings, the procedures here should work anyway.

Press the call button after entering the codes below:

Function Dial
Activate divert all **21*<voicemail>#
Deactivate divert all ##21#
Query divert all *#21#
Activate divert when no answer* **61*<voicemail>#
Deactivate divert when no answer ##61#
Query divert when no answer *#61#
Activate divert when not reachable **62*<voicemail>#
Deactivate divert when not reachable ##62#
Query divert when not reachable *#62#
Activate divert when busy **67*<voicemail>#
Deactivate divert when busy ##67#
Query divert when busy *#67#

*You can vary the number of seconds to wait before diverting when there’s no answer. The delay can be between 5 and 30 seconds. Enter that as a two digit number (05 to 30) in place of “<xx>” in the following code: **61*<voicemail>**<xx>#

Voicemail numbers

On the UK T-Mobile network, your voicemail number is usually +44063, followed by your mobile phone number (without the leading 0), e.g. if your phone number is 07123456789, the appropriate voicemail number is +440637123456789. Long-press the 0 key to get the +. BUT! in the voicemail number prefix (+44063) , the ’63’ may be something different for your phone – e.g. for the Fresh sub-network, the prefix is +44060. You can check the correct prefix by entering *#67#.

Voicemail numbers for other networks are more straightforward:

  • O2 901
  • Orange +447973100123
  • Virgin 212, or try prefixing your mobile phone number with +44002 (dropping the leading 0)
  • Vodafone 121

  1. Incredibly helpful – thank you.

    As useful addition – with Orange you can choose to set up a ‘Temporary’ voicemail greeting. This replaces your normal one for as long as you wish but does not delete your original message – making it easy to go back to your original at any time. While the temporary greeting is active the system can be optionally set to prevent the caller recording a message – potentially saving you a fortune in overseas voicemail retrieval 🙂

  2. Thanks man, even the Virgin helpline guy didn’t know what the divert calls ‘code and number’ was; to transfer callers to my voicemail.

    Really appreciated mate, thanks. 🙂

  3. Thank you so much! Been trying all kinds of other (albeit similar) “solutions” from all kinds of other forums, all with zero success – until this one.

  4. Thank you, thank you, thank you

    I’ve spent hours tring to get this sorted. worth noting that for Virgin mobile i had to use the full +44002 prefix to get it to work and on my Lumia 640 once set it shows the number as 0002 then mobile number.
