got my wife's Exhibit II (latest software) and the 4G Monthly plan w/5GB of 4G data. Storm came through and dumped all the power and cable broadband in the area, won't be back up for a week.
But I'm able to post here thanks to FoxFi. The whole house is happily on the net.
Let's see, last month--our first month trying this out--she used 167MB of her data allowance. The plan renewed Friday, then Friday at 5pm the power went out, and we've used ~650MB of data since then--just browsing the web.
shhhhhh, don't tell t-mo....but this experience has locked me into loving them and their service.
