How to Lengthen Ringtime on any O2 Mobile

[jonsie]

The following method will work on any O2 mobile and means you can control the time interval before a call goes to Voicemail.

Enter the following into your keypad as though you were just making a call :

**61*901*11*30# then simply press 'call'.

please note 30 is the time in seconds before voicemail kicks in and can be set in increments of 5 ie. 5, 10, 15, 20, 25 to a maximum of 30 seconds. (also see video)

If this doesn't do the trick try turning off WiFi and changing the setting network type to 2G only.

Alternatively, you can switch voicemail off completely by calling 1760 from your mobile when you know you will be available to answer calls. Switch on again when needed by calling 1750.

More info on Voicemail here : Using Voicemail | Support | O2

Just a tip : To avoid charges when travelling overseas switch off voicemail before you go as you cannot do so once you have left the UK

Well done @hayw77 you have cracked it! (The mentions and tags I mean)

[jonsie]

Well your solution will really help others because with wifi calling now there at the click of a mouse in My O2 then no doubt many others with incompatible phones could have the same issue. 

At least the code still works. 

Thank you @hayw77 😀

Oh thank you very muchly - this was very helpful indeed Fatboy.

I tried ringing **61*901*11*30# from my O2 bought Google Pixel phone on numerous occasions and always got

Connection problem or invalid MMI code.

So I tried this fandangle method of *#61# and collecting the phone number etc. and it worked!

Then strangely I tried **61*901*11*30# again, and it now works.  Whaddyaknow - perhaps your method has kickstarted the MMI into action.

Solved for me - and beats dealing with Customer Service.  Brilliant - I can now answer the phone!

That's the correct response, if that's what you're asking?
