On the R11e-LTE-US modem, is there a way to set the LTE band that it uses or a way to set an order of priority for the bands? I tried entering but no matter what I enter for the band, it says "input does not match any value of band." I am using AT&T 4G LTE, and I was trying to set it to use LTE band 2 or 4, which are in use in my area.

R11e-LTE-US not support band locking.

Regards.

You can get a Quectel EC25-AF on Amazon that supports pretty much every carrier in the US and it is quite easy to lock bands. I used it instead of the R11 and it has been working great.
