Straight Talk, a carrier formed from a partnership between Walmart and Tracfone, is now allowing users who bring smartphones capable with AT&T's LTE network to use the 4G data service.
I currently have 3 phones with Straight Talk. I have one that is unlocked that I will be switching now to AT&T. My question is, I also have an Iphone 4 and a Samsung Galaxy S3 that I bought with Straight Talk/ as Straight Talk phones. just visited my local AT&T store with the intent of switching my iPhone 4 from Straight Talk to AT&T and the employee working there told me that he had never successfully been able to port a phone number over from Straight Talk and that I would have to get a new number.
