No signal

[Vanek]

Hello! Bought xperia V week ago, phone is new. It begin lost signal from bad 3g to very good edge, but then it lost it absolutely to 0. Says that only emergency calls available. Restart helps some time.  Is that known problem? Any solution?

First of all you should try to change the network mode. If you still experience the problem you should try with another SIM card. 

If this doesn't work you should have the phone examined at a service center. Please contact your local Xperia support team for more information:

Same problem here. We have weak signal at home, but even if I get to well covered area the phone still shows "No signal" until restart. It really bothers me.

The phone is 2 weeks old and has newest updates installed.

Changing network mode didn't help either.

The same happens to my other phone with different sim card (Xperia Active). But Xperia Active at least finds signal after switching "flight mode" on and off.
