P.K.
How about forgoing the phone and have her call from where she is on their phone. From the beginning of time that's what kids did. She wants to walk home with friends. Again kids have been doing this for years and years and years. So if all her friends are all sick on the same day and not in school, if she has to call you, she asks the school office if she could use the phone. She is 11 and does not need a phone. If you must just get a prepaid phone from Walmart.
