Not in my neck of the woods it's not. I can barely even get a signal. I've been looking at some of the antenna units that are offered for picking up a signal from a local cell tower and broadcast the amplified signal to an area around the house. Anybody here ever see these in action?

Oops! My bad. Looked up what a GSM antenna was. Are the worth the investment?
More reliable THERE, as in Africa.
