Just bought a second hand samsung 360 h1 today, it works fine with no sim but when i put in a sim card (vodafone) it goes off just after the welcome screen. I have took the sim out again and now it works fine but obviously i can't make any calls. I had a look through the phone and have found some features that are normally only on contract phones , but i bought this from a shop and was aware it was pay as you go. Does anyone know whats wrong with it or what i can do to get it to work with my sim inserted? thanks for the help.
