Final tests: My phone is a Verizon it does work here on the farm---but not real good. My son has a Sprint---it does not work out here at all. I had him come over to play. We walked out about 25 feet from the GMC where we were both down to tower and 2 bars. We called each other---very clear. We then both called friends---same story. It can be used by more than one phone at a time. Final test---I uploaded the pics for this album on my cell phone---I have never had a connection out here good enough to do that. I am a happy camper.
