Sorry for the delay. Yes, the patch solves this issue. There are a
couple of complaints about the DMS version, but I assume those are
expected due to unsupported commands? And then there is a !NULL
assertion failing, possibly related to SIM initialization? The modem
was waiting for the SIM PIN at this point.

PIN verification using DMS and connecting using WDS worked fine after this.
But I noticed a minor issue when attempting to verify max bearer limits.
The only available bearer (BTW, not sure that is true - you can probably
do a PPP connection as well) is already connected:
bjorn@nemi:/usr/local/src/git/linux$ mmcli -b 0
Bearer '/org/freedesktop/ModemManager1/Bearer/0'
-------------------------
Status | connected: 'yes'
| suspended: 'no'
| interface: 'wwan0'
| IP timeout: '20'
-------------------------
Properties | apn: 'telenor'
| roaming: 'allowed'
| IP type: 'ipv4'
| user: 'none'
| password: 'none'
| number: 'none'
| Rm protocol: 'unknown'
-------------------------
IPv4 configuration | method: 'dhcp'
-------------------------
IPv6 configuration | method: 'unknown'
Attemting to create another bearer fails as expected:
bjorn@nemi:/usr/local/src/git/linux$ mmcli -m 0 --simple-connect="apn=mms"
error: couldn't connect the modem:
'GDBus.Error:org.freedesktop.ModemManager1.Error.Core.NotFound: No valid data
port found to launch connection'
But this is unexpected:
bjorn@nemi:/usr/local/src/git/linux$ mmcli -b 0
error: couldn't find bearer at '/org/freedesktop/ModemManager1/Bearer/0': 'not
found in any modem'
bjorn@nemi:/usr/local/src/git/linux$ mmcli -m 0 --list-bearers
Found 1 bearers:
/org/freedesktop/ModemManager1/Bearer/1
bjorn@nemi:/usr/local/src/git/linux$ mmcli -b 1
Bearer '/org/freedesktop/ModemManager1/Bearer/1'
-------------------------
Status | connected: 'no'
| suspended: 'no'
| interface: 'unknown'
| IP timeout: '20'
-------------------------
Properties | apn: 'mms'
| roaming: 'allowed'
| IP type: 'ipv4'
| user: 'none'
| password: 'none'
| number: 'none'
| Rm protocol: 'unknown'
-------------------------
IPv4 configuration | method: 'unknown'
-------------------------
IPv6 configuration | method: 'unknown'
So MM created the bearer and replaced the already connected one with the
new and unconnected bearer. That does not seem right?
