Which Carrier Has the Best Unlimited Plan? AT&T vs Verizon vs Sprint vs T-Mobile

I have an unlimited plan with T-Mobile for five lines and pay $220 per month including all taxes and fees.

I am currently in Iraq and get free texts and data. Calls to the US are .20 cents per minute.
The other lines are all in the US and get unlimited everything every month. One of those lines belongs to our foreign exchange student and she gets free calls and texts to Norway included in the plan.

So far no one else could beat this plan. But, maybe it's because I have constantly been with T-Mobile since 2004. Loyalty pays off.

T-mo, hands down, imo. They don't count ANY streaming of movies, tv, music against any cap you might have, and their 'unlimited' plan gives waayyy more GB's before they slow you to 3g (which they all do).
