[Networkmanager] Options for handling two sim slots?

[Fernando B]

Hi all,

I have a device with Telit LE910C4-NF modem. I am not exactly sure what
this setup is called properly, but there are two slots, slot1(ATT) and
slot2(VZW), however they're all routed to slot1 at the modem level, because
if I check with mmcli no matter which slot is enabled with moxa cli tool,
mmcli always shows slot 1 active. I can make nmcli connections to both att
and vzw, provided I manually switch to the right slot in the terminal.

Because of this slot switching it makes it difficult to use nmcli out of
the box, I was thinking of using dispatcher scripts when one connection
becomes active do the slot switching that way however is not liking it. If
I have the wrong slot enabled, the opposite connection just doesn't run the
dispatcher script and errors out.

What is the best way to handle this, an entire custom service and manual
handling of nmcli connections?

Thank you,
Fernando B.
