In the past few months each of the Big Four US carriers has introduced some kind of new service plan. So to help you figure out which plan gets you the most bang for your buck, I’m breaking down each carrier’s pricing for an iPhone 7 with a 3GB per month data plan — the average amount used by most smartphone owners, according to the NPD Group.

(Update: A previous version of this article indicated that Verizon charged $5 per month for its Safety Mode. The company, however, now offers the feature for free across its plans.)

I’m also including the cost of a 4-line plan with 3GB of data each for all of you family types, as well as the number of cities in which each carrier offers 4G LTE data speeds.

After digging through each carrier’s website and the various purchasing processes, I found that Sprint (S) came out with the least expensive monthly plans for single people followed by AT&T (T), Verizon (VZ) and T-Mobile (TMUS). If you’ve got a family of four, T-Mobile offers the cheapest plan, while prices increase with Sprint, Verizon and AT&T.

But a carrier’s worth isn’t just about its price. You’re also going to want to take into account its coverage. Sprint might be the least expensive carrier, but it only covers close to 300 million people. T-Mobile, meanwhile, covers 312 million and Verizon covers 314 million. AT&T, according to its own numbers, covers the most people at 325 million.

AT&T

  • Monthly cost when buying phone: $650 for phone, $60 per month for data

  • Monthly cost with phone installments: $127 for the first month, $87 each subsequent month

  • Family monthly cost when buying phone: $2,600 for phones, $170 per month for data

  • Family cost with phone installments: $358 for first month, $278 each subsequent month

AT&T’s Mobile Share Advantage plan gives you the option to either purchase your phone outright, or sign up for a 24-month plan. There’s a 30-month plan, as well, but we’re going with the 24-month for this exercise.

A single person

If you decide to pay full-price for your 32GB iPhone 7, you’ll fork over $650 for the device and $60 a month for 3GB of data. That includes a $20 per month device access charge. You’ll also be charged a one-time $20 activation fee, because carriers love money.

All told, you’ll pay $1,460 over the course of two years including the $20 activation fee. Throw in the price of the iPhone 7, and you’re looking at a total of $2,130. The benefit of paying for your phone outright is that you can then leave your carrier at any time.

Opt for AT&T’s Next Every Year plan, and you’ll enter into a 24-month agreement with the carrier that ensures you’ll be able to upgrade to a new handset when you pay off 50% of your iPhone 7’s price, which takes about 12 months. Under that plan, the price of the iPhone 7 breaks down into monthly payments of $27.09.
