European Sony Xperia Z

Hi everyone! I have an European (or International) Sony Xperia Z, which actually does not work with AT&T LTE /4G network. Is there anyway to make it work, maybe flashing an US firmware? Please help me! Thanks a lot.

It's a hardware problem not a software problem. Which model do you have?

Model FCC id UMTS bands LTE bands Carrier/region
C6602 PY7PM-0280 1, 2, 4, 5, 8 None[18] Worldwide
C6603 PY7PM-0270 1, 5, 8 1, 3, 5, 7, 8, 20[18] Worldwide

Agreed. If that phone doesn't support the bands that AT&T uses, then it's useless on that carrier.
