Hello,

I have an unlocked HTC M8 for windows that I use with a non Verizon SIM in Europe.

Phone is working great on 3G and 3.5G, but I dont have 4G.

The phone is hardware designed with 4G bands LTE band 3(1800), 7(2600), 8(900), 20(800) - EMEA and LTE band 2(1900), 4(1700/2100), 5(850), 7(2600), 17(700) - AT&T, but somehow the bands 3(1800) and 20(800) are blocked, because Verizon use only LTE Band 13/4 (700/1700 MHz).

It is a method with I can unlock all LTE bands in order to use 4G capabilities of the phone in Europe ?

Kind regards,

Gabriel
