Help mmcli - I don't know how to use a context other than the default CID 1

[John Thompson]

Hi

This started as an nmci question but I realised I don't understand how 
to configure bearer contexts with mmcli either.

My starting point was creating a connection using nmcli  (I wanted to 
really use ipv6.method "disabled" but that's another story.)

sudo nmcli connection add connection.id "eeno6" connection.type gsm 
connection.interface-name "" gsm.apn "everywhere" gsm.username 
"eesecure" gsm.password "secure" ipv6.method ignore


After this the modem has a context 1 setting like this

> ```
> at+cgdcont?
> +CGDCONT: 1,"IP","everywhere","0.0.0.0",0,0,0,0
> OK
> ```

But this is a bad idea - far better to use something other than context 
1 maybe context 3 instead.

Any ideas how I create a connection profile that uses context 3?

I am also interested in how modem manager creates and manages the modem 
context ?

I am not sure if modem manager writes the context only once when the 
profile is created or every time a connection is started by network manager?


For interest my test system has
> mmcli --get-daemon-version
> ModemManager daemon 1.14.10 running
> mmcli --version
> mmcli 1.14.10
> nmcli --version
> nmcli tool, version 1.14.6


Many thanks in advance

John
