M600 stops connecting!

[Guest Lammypie]

This is the 2nd Orange M600 I have owned.

Both exhibit the same problem

Periodically sometimes once every 2 weeks, other times 1 a day, it will stop receiving or making calls or sms etc.

The signal bar indicates signal. However anyone who calls gets diverted through to answer phone. If I dial out it simply doesn't work. I don't get any tones like there's an error. It just says dialling and doesn't do anything until I hang up.

The only way I can fix this, is by turning flight mode on or off, or turning the phone on or off.

It does this without warning. So if I'm expecting an important call, I have to keep calling the answerphone to see if its still working or not. and its getting a little frustrating.

Any one have any ideas?

Kind Regards
