Hello,

Here's the output of atinout:
```
$ echo "AT+CGDCONT?" | sudo atinout - /dev/ttyUSB2 -
ERROR
```
I confirmed that /dev/ttyUSB2 is the right device, as it responds with
"OK" to "AT".

Well that looks pretty empty... Is this user-configurable, or does
mmcli fill these in for me?

That's what "--3gpp-set-initial-eps-bearer-settings" is for, right? Is
there any other command that deals with the initial EPS bearer
settings?
It seems to me that merely entering the APN for the initial bearer
settings doesn't change anything, and I don't know which ip-types or
authentications this provider supports. I have tried some, and for some
combinations a "--3gpp-register-home" tells me it connected
successfully, while in mmcli I still see that it's connected to the
wrong operator. In fact today it has already connected to every
operator except the one I'd need it to. I also still can't enforce it.
Is there something like a command to generate a full dump of all
settings that mmcli works with, such that I could ask someone with a
working modem on the same provider to show me their settings?
Or maybe something like a full reset of all prior configurations?
Thank you!
