Hi, I have at the moment an O2 Pay & Go usb modem. I found out that I cannot use Steam with this modem for whatever reason. I only want to activate a game online.
But you cannot finish the process of installing Steam. Steam support confirm this is not possible.

As I google this problem online, I'm getting the hint that it may not be the case for all or this USB dongles and maybe buying a Pay as You go one from another operator like Vodafone or T-Mobile may work?

So just wondering if people with Vodafone or T-Mobile USB dongle modem can instal Steam with that connection. I suspect it probably will not. But all the same, Can you?
