Is there a way to force USB modems to use the 4G LTE band only? I have a SureCall AT&T 4G amplifier upstream of an AT&T USB modem (actually have been experimenting with both AT&T Beam and AT&T Momentum), and I think the amp only passes through signals in the 4G spectrum so I want to be able to tell the modems to operate using 4G only. Is this possible?
You need to configure this in USB modem. We can’t control this since this is not an embedded modem.
