My Xgody lost the sim suddenly! How to fix ?
Are you saying, its not reading the SIM anymore? If so open, it up and take a quick look see if there is any damage of any kind, if you see none, you may be able to visit a kiosk of your cell phone provider, they will need to replace the SIM card, im with Virgin Mobile and I am charged; $5 per replacement, they will adv beforehand, if any fees. Calling in in will help too but, they have to mail it.
I moved the sim to other phone, it worked fine.
