simple connect register throws warnings and takes long

[DN 19]

Hi,



I use a “Quectel Wireless Solutions Co., Ltd. RM520N-GL“ and mmcli version:
1.20.4 to connect to cellular neworks (in this example 1nce-network)



After setting the initialbearer

*mmcli -m any --3gpp-set-initial-eps-bearer-settings="apn=iot.1nce.net
<http://iot.1nce.net>,ip-type=ipv4v6"*

Modifying the nmcli connection

*nmcli c mod wwan gsm.apn iot.1nce.net <http://iot.1nce.net> autoconnect
yes*

and trying to bring up the connection.

*nmcli c up wwan*

The modem takes a really long time to connect to the network. It seems that
the nmcli does wait for the *modem state* to be *connected*.



I did grep the journal of mmcli to check what is taking that long and I got
some warnings in *simple connect state (6/10): register*.

*It seems like the connection process takes a long time during the errors

Any idea or recommendation, how I can fix it? Thanks a lot!
