I just got the BV9000 Pro, but all I am getting is the Edge network. I have edited and verified the APN settings, but there is still no 4g LTE. I have my old phone right next to me and when I put the SIM in it I get a very strong 4G LTE signal. I also copied the APN settings from it. No luck.

Is there anyone that has one of these working with 4G LTE on T-Mobile in the USA?

First you have to contact your phone carrier to get your correct APN settings, wich you have to set.
Then enable your data connection and everything will work.
