Metro is part of T-Mobile. T-Mo is generally pretty reliable and fast. They used to have a very limited service area, but they have expanded rapidly the last couple of years. If you have good T-Mo coverage you should be good to go. Just looking at their coverage map, you should have excellent service there.
I recently switched from Cricket (AT&T) to T-Mo after they started a new plan offer for those of us over 55. You get two lines unlimited everything for $60/month including taxes and fees. That's total, not per line. T-Mo in my area is at least as good as AT&T; perhaps a bit faster.
