After playing with the phone for some time, phone shows that there is no signal, I turn on plane mode and then turn it off, and phone says that there is no sim card insert.. most of time it happens when battery is low.
But there is simcard! And sometimes after restarting the signal comes back, but sometimes it comes back after removing and then inserting sim card again.
The sim card could be faulty, but I used it for 2 years and it worked good on my sony ericson, and problems with sim card started only with this phone. Maybe my dad inserted the simcard in phone to hard first time..
And the phone could be faulty, but I have already instaled there some third party apps. And I don`t know if I can change the phone.


p.s That happens almost every day..
p.ss android version 2.2.1. Should I upgrade?

Very common. Just swing into the store and grab a new SIM. They shouldn't charge you for anything.
