I keep losing my contacts that ive save to sim card some person messed with it and got it back but ive lost it again just says goto account but how... anyone help me
Mobiles usually give the option to save to the SIM or to the handset. Check the menus to see if you are looking at one and not seeing the contact stored on the other.
It doesn't hurt to either get a connection to your PC and software that will back up your phone: or a dedicated SIM card backup hardware. It's such a pain if you lose it and have to type it all in again.
