Phone is an older samsung x-427. It was working perfectly in december. I upgraded to a motorola razr at that time. Slipped the sim into the razr and put the samsung in the drawer. January the razr is stolen. Since I don't want to buy a new phone I purchase a new sim for the samsung and get "no service" on the display when I put it in. If I do manage to get a signal it drops after a minute. Swap sim cards with my wifes phone and get the same results. Can this be fixed?
