I have xperia sola and i'm very satisfied using it but recently I had a problem. At the notification bar a "Sim not allowed mm #3" message appear and my phone can't recive calls and messages, what do i have to do? It's very serious problem
, it's like i don't have a phone when it happens and sometimes it take hours to notice it. Help!!!

This sounds like the SIM card, I suggest testing another SIM card to see if this resolves the issue, if this does not help, then I suggest a software repair to fix any glitches the device may be experiencing.I have supplied the appropriate software below to perform this task

Me too problem

I have the same problem with my XA1, except only when I am thousands of miles from home and don't have a windows computer to do a data fix. It is happening on my main phone number and I don't have another sim to put in there, thus making me inaccessible by phone for emergencies etc. The irony is that this same phone and sim worked in the same place I am now having problems 6 months ago. I have tried just taking out the sim and putting it back, but that doesn't work.
