When trying to set the EPS bearer settings I get following error.
root@dev:~# mmcli -m 0 --3gpp-set-initial-eps-bearer-settings=""
error: couldn't set initial EPS bearer properties:
'GDBus.Error:org.freedesktop.ModemManager1.Error.Core.Unsupported: LTE attach
configuration is unsupported'
It doesn't make any difference whether I use a valid APN configuration or leave
it empty.
Possibly, that settings are preconfigured on the SIM and cannot be changed for
that private APN.
