The modem is requesting to use a specific APN named "internet" in the
initial EPS bearer settings. If registration is failing, try to reset
that APN to an empty string, e.g.:

$ sudo mmcli -m a --3gpp-set-initial-eps-bearer-settings="apn="

Or, it could also be that the network requires a very specific APN for
registration, if so, you need to check with the network which one it
is, and set it in the initial EPS bearer settings in the same way.
