For ATT 4G unlocked version. The easy way is open the back cover and replace ericssion edge 3G module or Sierra 4G module directly.....somebody did this way and succeed in China.
I did not have to change the modems, one issue is the serial number though, I ended up with 3 devices using the same serial number (not Imei)
