Plain and simple...which cell phone carrier has the best coverage?

[R=G]

I have Project Fi, it uses T-Mobile Sprint and US Cellular towers. It automatically switches between them. I have never been without coverage in like two years. Only problem: nooo unlimited data. $10/GB month. $20 talk/text

that plan looks SO bad, man

I'm in the DC area.

Then go with tmobile

Tmo is neck and neck with Verizon as far as coverage in the DMV

Verizon is better but its close and tmo is alot cheaper

I thought it was Verizon and AT&T before I started traveling. I have T-Mobile now and I have coverage where I expect to have it. I don't run into any issues and can't tell the difference from when I had AT&T.
