Will A Locked At&t Phone Work On Straight Talk. Unlock as in SIM-unlock. Hope this help clear any issues.
With Straight Talks Keep Your Own Phone program you can get Straight Talk service on your current phone as long as it is compatible with our KYOP program. As in you cant use a CDMA phone Sprint Verizon on a GSM carrier ATT TMobile But if you want to swich from. The phone must have been activated on Straight Talk.
Id start by borrowing a ATT SIM from a friend and putting it in your phone.
Compatible phones include ATT Compatible phones T-Mobile Compatible phones Sprint Compatible Phones as well as most GSM and CDMA Unlocked phones. Hello I was reading through this conversation and am wondering if I can buy an ATT iphone 5 and just put the new LTE ATT compatible ST sim in it I have an ATT iphone 4s on straight talk right now but it is unlocked so my question is can I use a locked ATT iphone 5 for straight talk some people say no you must have it unlocked but there. Do new Cricket SIM cards work in a locked ATT phone. This does not include ATT Go Phones.
