@loganwilliams it will probably work fine... The big requirements are: 1) need to be able to use the USB-TTY to communicate with it (using the 5v to power the shield, unless you have a separate power supply)
And 2) it needs to have output consistent with the other modems in the pile I've accumulated so far :-)
Chances are, it'll be fine.
I'll have a few known-good with me.
In case yours doesn't work quite right, you've got dibs on one.
