Hey! I bought a verizon phone (sch-i545) and as I am moving to france, I would need some help. It is unlocked and have my french simcard inside, but when I do unlock it, my phone sends me a notification about phone activation saying the sim card is from unknown source. Because of that, I see that the phone recieves data and is connected to the network, but when I try calling someone, the phone won't let me do it and when someone tries to call me they directly go to the message reciever. Could you help me with that, because it would be preferable not having to buy a new phone. Thank you very much.
