i've used simple mobile since march and havn't had a problem. like streetman said they recently updated their service for a 60 dollar unlimited talk, text, and web. once you get your sim and have paid for the plan give them a call and they will walk you through the steps so the phone can get on 3g. call from a different phone. if you don't want web there is no need to do anything the the phone, just put the sim in and your good to go.
