Xperia P SIM detection issue

[x-calibre]

My wife has been using the Xperi P fr sometime now, and it was working fine up untill last month when she went to China and used a local SIM there. Since her return her phone has failed to recognise any SIM (I have had 3 duplicates issued) with 'her' number. Eventhough the same SIMs work fine in my Xperia T and my same network SIM works fine in her phone. I have even tried reseting the phone twice but with no luck. It just doesnt recognise her numbers SIM, keeps asking for a SIM to be inserted.

Your wife could have damaged the SIM place when she inserted the SIM card from China,maybe they are a little bigger or different from ours.You could have your phone checked at a sony center,that is my opinion.

Only her SIM is the problem?In China did it work fine all the time?Maybe it is not active anymore.

Its not the SIM, as the SIM works fine in my phone + ive had the SIM replaced Thrice. It worked fine in China, and even if the Chinese had SIM messed up the settings, ive Reset the phone twice

I am sorry to tell you,but it is very awkward.You should take the phone to a sony center and have it checked.
