Hi, I've got a panasonic X800. I bought the phone and it was unlocked. I was using my Fido (Canadian carrier) sim in it perfectly fine. All of a sudden, I took out the sim, put it in my nokia 6800 just to check something, then when I put my sim back in the X800, it gave me the message "Insert SIM," the typical your-phone-is-locked message. Does anyone know what I can do? Any help would be appreciated. I guess remote unlocking might solve the problem, but I dont see how, since the phone was already working fine with the sim. The sim still works fine in the 6800...soooo? Thanks! BiGaSiF
if it "insert sim" its not simlock... its bad simcard or reader.. test another card, clean the reader and "push" on the legs, and it´ll be fine...
