I ported over to ST yesturday morning, got a confirmation text stating that the port was complete. I can make call and send text messages, but I the data is not working. I have set up the APN exactly as instructed by the red card that came with the sim card. The phone I'm using is an unlocked ATT branded Motorola Atrix 2. I checked the coverage area for ATT in my area and it looks like there should be good voice and data along with 4G LTE service which I know this phone is not capable of.
