If you can reach the VPN you are trying to connect to via IP it should work.

As rick say you should be okay.
PPTP VPN is (pretty) standard IP traffic using port 1723
But, router (i.e. AT&T router) need to have protocol 47 GRE enabled to support the routing of encrypted traffic. Read more here: http://en.wikipedia.org/wiki/Generic_Routing_Encapsulation

But i've used several 3G cards with no problem with PPTP
