problems with the o2lte command
Checking on multiple different lte boards, I noticed that once connecting to an apn ( i tried hologram and tmobile ) turning off the data connection doesn't seem to work. Even though o2lte says it turns it off, the interface is still there, it still has an ip address and traffic is still routing out off it.
There also seems to be an issue switching from one apn to another. If I add a sim after a fresh restart, it will provision it correctly, but if I want to switch to a different sim and run the apn command again, it doesn't switch correctly.
data disablecommand shuts off the
lteddaemon. See the source here: https://github.com/OnionIoT/OpenWRT-Packages/blob/openwrt-18.06/omega2-lte/files/omega2-lte.sh#L195
That should disable the data connection. Have you found any commands that work to disable the data?
Maybe try out ifconfig down-ing the lte interface.
