I have a ZTE MF286D cat12 LTE router and installed OpenWRT on it. The software is nice, however I had troubles setting the telco operator's APN properly.
The problem lies with this being a 3UK "locked" device and even though we have changed the OS with OpenWRT the modem device still has the old settings.
This can be sorted by interacting with the modem and setting the APN using AT commands.
