I did not have any cell reception at my camp where my camper is setup for the year. Its located on top of the mountains that are fairly high in elevation. The YX510-PCS-CEL did get me a bar, sometimes two bars of service where was no service shown on my cell phone previously. I now have Cell Service and Internet Service that seems to be decent in quality. I recommend this device to anyone where cell service is present but has a weak signal. Consumers do need to remember, it cannot amplify nothing. There has to be at least something of a signal to amplify.
