I do satellite installations all over western kansas and well there is nothing out there and very little cell phone coverage. But i did go to one customers house that was in a valley and standing outside phone in the air I might get 1 bar but it would drop as soon as I moved over a foot. He had what looked like that exact one hanging in his living room and i was able to talk on the phone through-out his house no problems......1 bar solid signal. So i would say they work good for voice but can't say anything about data because i didn't use my phone for that when i was there.
