The Big Four carriers’ shell-game-like pricing practices have become so convoluted, you need an accounting degree to decipher them. They continually shift prices up or down according to the number of phone lines you need and the amount of data you're purchasing. They further complicate matters with “special” short-term offers to lure customers from rivals. We’ve decided to omit these specials from our calculation tables because of their extremely short lifespan and their fragility (deal benefits often vaporize when a customer buys a new phone or makes other changes). The good news: Some of the wilder, fly-by-night plan pricing seems to have abated—at least for now. And in some ways, comparison shopping has become a tiny bit less onerous.
Here’s a short rundown of the major carriers. (Read our review of the best cell phone carriers to find out whether the small providers outpace the big companies.)
T-Mobile
T-Mobile doesn't offer data-sharing cell phone plans. You have to purchase data for each phone in your household. The carrier’s plan calculator has been tweaked to present your options more clearly than before, showing you the immediate impact on your total monthly bill as you add or subtract phone lines and experiment with the data allowances for each phone. T-Mobile’s plan costs are only slightly cheaper than those offered by telecom behemoths Verizon and AT&T, but the carrier does have an additional edge for media streaming enthusiasts: Content from Spotify, Netflix, and a plethora of other popular music and video providers doesn’t count against your data allowance.
Sprint
Sprint is among the lowest rated carriers in our Ratings for both monthly billed service and its prepaid service. And it used to have one of the most convoluted phone access fee menus, ranging in price from $15 to $20 to $25, depending on the size of the data bucket you purchased. But it’s made some significant improvements. It now charges a flat $20 per phone line, while its plans are a bit cheaper, too, even besting bargain-champion T-Mobile in some instances.
AT&T
AT&T stubbornly clings to variable-rate access fees that can mislead customers into spending more money when they’re trying to save. For instance, it charges less per phone ($15 instead of $25) when you buy more than 5GB of sharable data. And that kind of pricing could lead a data-frugal family of five to pay more a month ($225) for sharing 5GB of data if they don’t have the math skills to see that splurging on a 15GB data bucket would actually lower their monthly bill to just $175. One saving Grace: AT&T's customers gave it good marks in our survey for voice, text, and Web service.
