Hey I need your help. I'm looking for a phone for my 10 year old daughter to replace my motorola razor (T-Mobile). I want to check for used ones. She wants the phone to have a sliding keypad. So how do I know if a phone is compatible with my current sim card? I don't want a smart phone! She will not be having internet. It is strictly a phone for her to take to school on days when she stays after for activities.
Thanks a Bunch, Katie
