Since last week I have been unable to make calls on my phone and at times have not been able to receive them.
When trying to dial out I receive the error message: call failure, the call could not be connected, please try again later.
This seems to happen whether I am dialing an O2 number or other networks and local/national numbers.
I have received a couple of calls from other networks and local/national numbers but had problems with people dialing in from O2. When people using O2 tried to contact me they were diverted straight to voicemail and sometimes I received a text to say I had a missed call.
I have also had problems at times sending and receiving texts.
I have looked online where people suggest looking at call forwarding settings but when I go to that screen I get an error and am unable to access the settings.
Anyone any ideas?
