Hi I was wondering if the T-mobile $10 data plan is what I think it is. Is the plan guaranteed $10 a month (or $10 extra on your bill) for 2 years with 200 mb of data a month? Or is it $10 for a certain amount of time then it goes back to its regular price? Also will it be compatible with my plan "Even more for Familes 1500 talk"? Thanks for any information.
