Do you have a recommendation for gsm usb sticks? Where do you get them?
Do you use just one SIM card at a time, or do you have a usb stick that can hold (and operate) multiple SIM cards simultaneously?

I have a few USB sticks plugged into a powered USB hub and Gammu watches all of them for inbound messages.
