Need to find cell carrier in USA for Quectel EM06 4G LTE Module

I have searched the carriers from the compatibility link and non of them will allow the Quectel device on their network.

Did I search for the wrong brand ( Quectel )name, if so please let me know the correct search criteria for this 4G module.

Which 4G module you used? A or E? Have you attach the LTE Antenna?
Which system you used?

It will be the A version for USA market. I have not yet purchased them because I need to verify the service provider.
