I am not familiar with the gophone. My daughter is 12 and we just added her to our plan. It was $9.99 a month to add to our plan. We got her the motorola razor because it has a lock feature. We locked her address phone so that she could not add names to it. We locked her phone so that she could only send and receive calls from people in her address book. People not in her address book can still call her, but it goes right to voice mail. They can leave a message and she can call them from the home phone. For her birthday she wanted a not motorola phone that does not have this feature. AT&T has a new smart limits plan. You control her phone from the internet. You control times she can use her phone as well as numbers. We felt that the $9.99 was a better deal than any of the $20 gophone plans. Good luck.
