Turns out that the phone does not support T-Mobile LTe bands (2, 4, 12, 66, 71) and uses different frequencies.

This phone WILL NOT WORK for ATT, TMobile, or any of their subs for LTE in the US because it lacks the required LTE bands.

this phone does not work with tmobile all 4g bands and they do not say it in the description, it is a scam.

Wrong band or something.

The camera on this phone is phenomenal... not as great as I had hoped but so much better than I anticipated for a $200 phone.
