Setup of AirCard 340U under ubuntu 23.04 as SMS gateway

Firstly I could not find an appropriate tag in the dropdown, if you can let me know where this should go I would greatly appreciate it.

Hi all, I’m new to this modem and tried a few things to communicate with the modem with no luck.
The modem is detected $lsusb shows
Bus 001 Device 044: ID 1199:9051 Sierra Wireless, Inc. AirCard 340U
When I try to list the port it is connected to I fail to make any sense of it. Neither ports ttyS or ttyUSB yield any accessible port, I tried a few random ports but just can not communicate using Minicom via AT commands.

It shows in the Ubuntu interface as a network connection, however I can not initiate it to make a connection.

Totaly lost :frowning:

Thanks in advance for your help

Hi @dirk.eisner,

Are you referring to the NetGear AirCard 340U?
I have information that since April 2013, all AirCard Mobile Broadband Devices are marketed, sold, and supported by NETGEAR, Inc. So, please refer to:
