I have a Samsung Galaxy S & live in a small town in Newfoundland that has no cell service. I bought a signal booster & it works great everywhere else except here in town. The thing is I do get 2 bars (out of 4) but for some reason it will not let me make a call. The HSPDA/3G icon at the top of the screen doesn't show, while in town, only the bars do. What could be the problem?
