I haven't seen our company listed in this thread: T-Mobile with Samsung smart phones. But we're on a daughter's family plan and she insists that it's only $10 a month (I have my doubts) without any restrictions. Anyway, I recently gave her $240 for the 2 of us for a year. My cell phone is rarely used. My wife's is used every day.
If it'll ease your mind, Bird, we are also on a T-Mobile family plan. The first line is fifty bucks, the second is 30 bucks and every line after that really is only $10.00.

I'd add my in-laws' to ours too, but my wife's brother is taking care of that for them. All the lines have unlimited talk and text and data. However, the high speed data is limited to 1Gig per phone. If you go over that, it throttles down to lower 3G speed. The kids watch movies on their phones, but they do it over wifi in our house or their apartment/dorm room, friend's houses, etc... so it doesn't count on the cell data plan. Also, T-Mobile allows free music streaming over the cell plan, so that doesn't count either.
T-Mobile is great on those respects. However, their service coverage tends to be great in towns and cities, but drops off horribly as you near cornfields. Also, even though they have great coverage inside cities, as someone else mentioned, they don't penetrate inside buildings too well for some reason. Step outside and you get full bars. Step towards the inner-most portions of a large building and zippo.
At our rural property, you'd think going up to the highest point would get you the better signal, but I got none there. I've found it strongest down in the lowest portion of our property, which is in a creek valley, that's kind of a funnel with the big opening facing town. So I'm guessing it gets forced into there against the hills on both sides. Anyhow, if I ever have a farm accident out there, I hope I can crawl down the hills to the low spot before I bleed out!
