throw off calls

[MarchJJ]

Hello!

I've got a problem with my Xperia P, which I bought in July 2012. All the time I used the smartphone, it throws off about 40-50% of incoming and outgoing calls by itself. SIM card works without any problem in my previous phone. I tried to return the smartphone, but according to conclusion of quality inspection, device is non-fault. What the problem could be? The software is of the latest version and it had been repaired to factory setting.

Did you buy an original micro sim or cut your mini sim to micro sim?

I agree with Sagar, just get a brand new MICRO SIM card

uninstall antivirus and/or taskillers and try again

SIM is original, it was not cut, all settings are as factory. But I can't use phone for intended purpose.
