hello. there is often a diagram which shows u how to insert the sim card. it will be a little diagram of a box shape with a **** on one side, as ur sim has a **** on one side too. try looking for it. the sim insertion can be under the battery, or more rrarely- thru the side of the phone. dont get confused with where the memory card fits, it is much smaller in size.
