If you haven't bought it yet, you may want to consider the no contract option temporarily. I saw a post on slickdeals that was advertising $30 off second month bill with no contract for T-Mobile. There is a flyer that you have to take to the store.

Potentially, you could try the service for couple months and if you don't like it, you could likely just stop using it. I think the deal expires on the december 31st if I remember correctly.

Good luck!
