(I write from prior experience with their service)

I can write about Sprint as well, they will out right lie to you, put phantom charges on your account, and their coverage is even worse than T-Mobile. And you will be lucky to get above 3G if you are lucky.

Both companies offer unlimited data. But throttle.

Verizon may not have the best customer service, but they have the largest network right now. And AT&T is right along with them.

Decisions decisions!
