The other day, my business partner and myself were traveling together though rural Kansas when he received a call from one of our associates on his S3. The call dropped so he tried to return the call. It too dropped. The business associate then called me on my Rez and we discussed the matter at hand and hung up. With nothing better to do, we then started comparing the Rez and the S3 as we went down the back roads of nowhere. The S3 zero internet... the Rez 3g. I had three bars sometimes four and he had one at best. I'm still impressed!
