When it worked, I would get 5 bars for about 10 seconds. Power if off and back on it would do the same.... Tested on 2 different phones (iphone and blackberry.)Vendors technical support was nice, and suggested that I purchase the outdoor antenna. I move the complete unit outside and still had to luck.I was in luck in that AT&T; was offering their micro cell in my area for $150.00 and it works perfect. As normal, no return issues with Amazon.
