Currently for me 4G is the only option to work remotely (the only alternative would be going with a wimax provider, or sat). I don't normally incur in the data size caps, but I will soon in the current situation, even when trying to be conservative.

It also doesn't seem worthwhile to switch at the moment, since other solutions require a 1-2 year contract which I do not need (not to mention, it would also take 2-3 weeks to get a connection with those anyway).
