Signed up this morning.... it's a great deal for me, as I have really good T Mobile coverage where I live. Already in the past few months, my bill for 2 lines has fallen from $109/month, then to $100 when I switch from my old grandfathered plan to the T Mobile One, and got lots of new features besides, like NOrth American calling. Then to $80/month when I activated kickback and saved $10/line. Now it will drop again to $60/month for my 2 lines. Not to mention all the free stuff I get on Tuesdays, courtesy of T Mobile. I must be one of the few folks in America that's really happy with their cell phone carrier.
