In any case, my advice to anyone looking to get a mobile service at an address they will use frequently is to find people who subscribe to different providers and ask them round to your place. Then check the signal on their phones. There are free apps which give you detailed information about the frequency used, signal strength, latency etc, but just looking at the signal strength indicator on the phone would be a reasonable guide.
