Older modems are /dev/ttyUSBx or /dev/ttyACM but newer modems might be using the MBIM [1] standard and don't really expose AT interfaces to the user.

MBIM does however expose an SMS and voice interface - if the device supports it. Though I can't see an obvious way to access it with the kernel API.
