I just got an unlocked version of the Moto X through the sale earlier this week and when I put my sim card in, I only register HSPA.
The card was just in my iPhone 5 and got LTE no problem.
I called AT&T, two reps made me turn the phone on and off about a dozen times, checked SIM and IMEI numbers, etc., it still doesn't work.
Anyone have any advice?
[UPDATE: Just checked on another forum, found the fix: Settings->Wireless& Networks>More->Mobile Networks>Network Mode: AUTOMATIC-- nothing was checked on mine previously. All good.]
