Text message everyone I ring T-Mobile voicemail

[Guest munrobasher]

I'm using an unlocked Vodafone v1415 (rebranded HTC S710) and everytime I ring T-Mobile voicemail, it sends me a text message from PERS. The text message doesn't appear to contain anything useful. The recorded voice message is different as well. It says something along the lines of "A message has been sent to your phone to configure it, please turn your phone off and back on again". I can then get to my voicemail okay so it's not the end of the world. Turning the phone on and off as instructed doesn't help.

Any ideas whether this is a problem with the phone or T-Mobile and can it be fixed? Maybe it's something to do with MWI (message waiting indicator) but that bit is working - I get the recorded message symbol fine. Maybe it's trying to program my keys but press-and-hold 1 works fine - calls 123 fine.

Any ideas?

Thanks, Rob.

PS. Can't get into voicemail at all right now...

"A message has been sent to your phone to configure it, please turn your phone off and back on again".

Actually, it says "The voicemail access number has been sent to your phone" and the text message is from "Pers" and says "Network message, please delete!"

Cheers, Rob.

PS. Voicemail started working 5 mins later.
