I got some advice from Plasma Mobile matrix chat resident dev Bhushan Shah.
qdbus --system org.ofono /quectelqmi_0 org.ofono.SimManager.GetProperties
Take a note of the SubscriberIdentity here. (You can ignore that command and instead find IMSI from system settings cell information.)
After that, in settings > Cellular Network > Access Points, check which of the context or APN makes most sense for your network if is e.g. 1st. Then
sudo nmcli c add type gsm con-name "/quectelqmi_0/context1/<IMSI_HERE>" ifname quectelqmi_0
And one last thing is to disable context from ofono side to let nm handle that [by running this python script -
cd to the directory you saved this script and run
After that activating newly added connection should work ™️
I’d love to hear if any other users are able to get mobile data running with these instructions because so far it didn’t work for me I just get the following from
quectelqmi_0: using connection '/quectelqmi_0/context1/46xxxxxxxxxxxx67'
quectelqmi_0: connecting (prepare)
quectelqmi_0: connection failed
