How do I change the number of rings on my Sony Xperia before it goes to voicemail? I have tried entering **61*901*11*20# and calling but I alwasy get "connection problem or invalid MMI code".

See this guide

You may have to turn off wifi calling as codes cannot be sent over wifi.

You need data on, it's just wifi CALLING that must be off.
