T.D.
Have you called t mobile or gone to the store and talked with the people that deal with the service and are trained on the phones to know what features each phone comes with?
They also make wrist watches that are basic. They call, they text. and can be located by gps. My friend got one for her son when he entered 3 rd grade because he would be walking to school. She loves it and recommends it. But I don't know where she got it or which phone service she has.
