unlimited data plans

As if there weren’t already enough options for unlimited data plans, even U.S. Cellular recently joined T-Mobile, AT&T, Sprint and Verizon on the limitless (but technically limited) data train. Here’s what you need to know about the four largest carriers’ plans and their coverage areas.

But first …

Do you really need unlimited data? Carriers will tell you how much data you’re using each month. To find out how much data you need, look back at your previous months’ usage (which is usually on your bill or in your carrier’s app).

If you use less than 6 to 8GB, depending on what your carrier offers, you probably don’t need an unlimited plan.

The carriers like to fight over which one has the best coverage, luckily for us, there’s RootMetrics. This company independently tests carriers’ networks and puts out RootScore Reports of its findings every six months.

Right now, RootMetrics ranks Verizon as the best carrier. This takes into consideration Network Reliability, Network Speed, Data performance, Call performance, and Text performance. And, actually, Verizon swept each of these categories to win the overall “best” title for the seventh time in a row.

AT&T took second in the overall ranking, followed more distantly by Sprint and T-Mobile was last.

Keep in mind, though, these are national rankings. So, depending on where you live, it may be true that Sprint or another carrier has better coverage in your area. To make sure you’ve got a network that’ll keep you covered, look up your home and any other important addresses in each carrier’s 4G (data) coverage maps:


All of these carriers offer “unlimited” data plans, but even if that company advertises the plan as being “truly unlimited,” it’s not. Every carrier practices throttling on unlimited plans at some point. (See the table under the plans heading for information on when each carrier will throttle.)

Throttling happens when carriers make your phone’s data run extremely slow to limit bandwidth. Carriers will usually only throttle a your internet if you hit a certain threshold and you try to connect to a congested cell tower. Congestion happens when an extremely large group of people (like a packed major league baseball stadium) all try to connect to the same tower at the same time. If you’ve used more than — say — 22 GB, your internet usage will be slowed to a crawl while someone else, who hasn’t hit 22 GB, gets priority.
