I dropped my T Mobile contract years ago and got a Straight Talk phone. Love it. I don't have the Rewardable app, but I do have Geoverify and it works on mine. I recently got a new phone, a Lightening ZTE Smart Phone - they were offering a promotion, the phone was $50, and it included $45 phone card so I only paid really $5 for the phone. My daughter got an I phone for straight talk and she is in heaven. So I would say go for it. They have a lot of options now.
