Does anyone know where I can buy one?
ebay…
Thanks but their isn’t any MC8790’s listed right now
So I was just talking to a supplier for this card and he was telling me that I would need to get the whole solution certified by the carrier. Does anyone know anything about this with the Routerboards?
Sprit ?
At&t in the US
Check with Brian over at Baltic Networks..
He has been putting RBs on AT&T with Sierra wireless cards for a while now…
Am sorry…
I was mean mc8780.
I have one, and works perfect with rb411u 
Did you order MC8780 ? if not you can use MC8790 which is latest one but if your area was UMTS Network.
