My two year contract on my iPhone 6 is getting ready to end soon. The plan is to keep my phone for one more year (maybe two). I'm currently paying $60/month for 3gb/200 texts with AT&T on my parents family plan. Normally I go over my data so I always pay them $70/month. I think I can do better with a prepaid service. If you've made the switch who do you recommend going with? And can you port your existing number? I've had the same number since '97 and don't want to give that up.
