my visual voicemail and imessage are not working!! please help
I upgraded my iphone to a 4S 3 weeks ago. Initially the visual voicemail and imessage worked. For the last week neither has worked. Every time i try to active imessage it says that there is an error. Regarding the voicemail- i occasionally get visual voicemail messages if i switch off the phone and turn it back on but generally they dont come through so i am not aware that i have received any messages. my phone will also not send mms messages! I have tried restting all the settings and have also restored my phone to factory settings but this has not fixed the problem! I had no problems with the 3GS phone!! Can someone please help!!
thanks
