r11e-lte-us band locking

Need help on lte band locking. So l can still on the best lte band. When I use at-chat I keep get a error “output error”

Never worked for me either. Pretty sure it’s not currently possible on the US R11e LTE modem (but works on the Int’l one)

Another posting was requesting it as a feature:

this feature is currently not available for US modems

When will this be available for us version?

Never?

I’d really like to see this implemented
