I am so impressed with the 3Gstore!
I had been researching air cards, and found the InterntByDataCard Yahoo!Group that had many helpful comments by Alex Sian of this store.
So I sent the 3GStore some private e-mail, and they answered all of my (many) questions quickly. Once I ordered, I received the merchandise promptly, and everything worked perfectly together. They even pre-activated my modem and updated the firmware in my router before shipping.
As it turns out, one small radial element was missing from my shrink-wrapped Wilson antenna, and after a quick e-mail to the 3GStore, they immediately responded and put a new one in the mail.
I only wish that every store was this helpful, responsive, and a pleasure to work with. These guys are awesome.
