If your contract is up it may be time to give Straight Talk a look. They will sell you a SIM card for for your existing AT&T phones. If you are looking for new phones then may I suggest Ting. Their service uses the Sprint network. What is unique about Ting is each device you use on their network is $6 plus whatever amount of talk+text+data you choose. These are pooled so if you add a device you only add $6 to your monthly bill. But what I really like and can't wait for my existing contract to expire is their version of rollover. Say you pick the 2Gb data for $45 to use amongst your 3 devices but find out you are only using 980Mb...Ting will credit the difference between the 2Gb and 1Gb plan ($18) and automatically drop you to the 1Gb plan for the next month. Same goes with voice+data. It works the other way as well so no overage fees if you use more than you expected. It all sounds too good to be true but I haven't seen any real complaints from customers. You do pay for the phones. They have a decent selection of Android phones including the Galaxy S III and Note II but no iPhone or BlackBerry devices for now. They just added the ability to bring certain Sprint phones to their service as well.
