I know like me lots of people no longer have land lines. We recently moved to a new house and our cell signal inside was either 1 bar or no service.
We went by and talked to the AT&T store they offered us a Micro-cell for $75.00 with a $75.00 rebate, essentially FREE
Now our phones have great signal around the house and only our phones access the micro-cell.
Of course it should be free since they claim to have coverage in our area.
Just a little FYI in case someone has a weak signal at home.
