I bought this Samsung GT P7500,international version and i appreciate itsb sensitivity,sound quality
It has a very good video recording of picture and voice clarity
Bt my worry is i could not use it as a phone,when i insert a SIM card ,it still insist that:Insert Sim card.
Now my question is ,does it ned to be unlocked or something needs to be done?
I tried several diferent Sim cards,
Cant you use it with any Sim card elsewhere??
