Selecting a wireless carrier is just as important as picking a phone. The provider, after all, delivers the network that makes your handset work. And since you'll probably end up paying a healthy amount for that privilege, there's no point in sticking with a bad user experience.

Fortunately, CNET is here to help guide you through the decision process. Read on for the major factors that you should consider when choosing a carrier, followed by brief descriptions of each of the major players that CNET reviews. Also, be sure to consult CNET's cell phone buying guide and our feature on which phone to buy.

Five rules when choosing a carrier

1) Coverage is key You can't do much on your phone without a signal, so make sure that you can get coverage in the places that you'll need it. That means looking beyond carrier slogans and coverage maps (though the latter is a good place to start) and doing your own research.

In all seriousness, the best way to gauge coverage in your area is to ask your neighbors. See which carrier they use, and ask if they're satisfied. You even can borrow a friend's phone and use it at home and in your workplace to see if you'll get the reception that you need. Sure, it's a very unscientific method, but personal experience is really the best tool.

Just remember that no carrier network is perfect. Gaps exist, even in urban areas, and reception can vary by your precise location. For example, a carrier's signal may not penetrate deep into buildings and underground, and it will vary according to how many people are using a network at a given time (think about how hard it is to get a signal at a big public event).

Another point to consider is whether a carrier uses GSM or CDMA. GSM (think T-Mobile and AT&T) is the dominant global technology and is used in almost every country around the world. So if you're a globe-trotter and want to take your phone on your travels, make sure it supports GSM. Though strong in North America, CDMA (think Sprint, Verizon Wireless, and most smaller carriers) is present in only a handful of countries outside of the United States. If your phone is CDMA-only, your international coverage will be limited. Fortunately, handsets that support both technologies are widely available at both Sprint and Verizon. GSM phones also are easier to unlock, meaning that you can take them to another carrier as long as your chosen device supports the necessary cellular bands.

2) Data speeds Of course, making calls is just one thing that you'll do on your phone. And if you're like a lot of smartphone owners, it may be the last thing. That's why you also need to carefully evaluate data networks. Data networks enable your handset to access the Internet, send e-mails, stream music and video, and download the apps that have become so popular.

Most U.S. carriers in the United States are now locked in an always-evolving race to build the largest and fastest 4G LTE data network. So just like with a provider's voice network, data coverage and strength will vary widely by area. If you want LTE (and really, why wouldn't you?), know where the carrier has 4G coverage and how fast it is. And just like with calls, make sure you've tried a carrier's data network before committing.

3) Plans

After coverage, your service plan is the most central component of your carrier experience. It dictates how long you have to stay with a carrier, how much data you'll get, and the price that you'll pay each month. Be sure to get what you need, but don't overspend, either. And remember that monthly taxes and fees will add more dollars to your final bill.

Plans that require a contract are still the dominant service model, but that's changing. T-Mobile, for example, ditched contracts completely in April 2013. Signing a contract entitles you to a heavy discount on a phone up front, though the trade-off is that you'll continue to pay for the device through the life of your agreement (and even after). With a prepaid plan, you'll have to pay full price for a handset at the time of purchase, but you'll be able to end service with the carrier any time you'd like. As you'll see in a moment, T-Mobile has adopted a somewhat hybrid of the two concepts. Here again, just think carefully about what's right for you.

Though the price of a calling plan used to be dictated by how many anytime minutes you had, unlimited calling is now largely the rule. Messaging tends to be unlimited, as well, which removes the need to buy a separate bundle. Instead, how much data you'll use now determines the cost of your plan. Some carriers have unlimited data while others restrict you to a certain amount for each month (what we call tiered plans). Once you go over your set data amount, you'll have to pay big fees. Alternatively, if you're getting service for a family or group of friends, shared plans will pool voice and data use across multiple devices.

4) Your phone
If your heart is set on a particular phone that's available with only one carrier, then you may have skipped the previous points entirely. But if you've yet to decide which handset you should buy (again, see CNET's cell phone buying guide or this feature for more help with that process), don't assume that each carrier's device lineup is the same. Selection varies widely, so it pays to think about which kind of phone you'd like and which carrier(s) offer it.

Up until recently, contract-based carriers strictly limited how often you could buy a new phone with the subsidized price, even if you extended your contract. But over the past year, the largest providers (following T-Mobile's lead) have introduced early-upgrade plans that have changed the roles. Terms will vary as I'll explain below, and they're not the same value by any measure. Maggie Reardon has an excellent comparison of the different upgrade plans .

5) Customer service
Unfortunately, there's no way to predict this. For everyone who has a horror story with a provider, there probably are almost as many people who have had no problem. Also, though consumer studies singing the praises of different carriers continue to get headlines, there are no guarantees. So all you can do is make your choice, hope for the best, and be your own advocate if you aren't pleased.

Carrier basics

Verizon Wireless

The biggest wireless carrier in United States, Verizon Wireless operates a robust and far-reaching 4G LTE network and a strong lineup of smartphones, feature phones, and basic handsets. A joint venture between Verizon Communications and Vodafone, Verizon Wireless was formed in 2000 through a merger between GTE Wireless and Bell Atlantic.

Things you should know about Verizon Wireless:

  • Verizon has a "Share Everything" plan that includes unlimited and text and voice calls for multiple devices plus a monthly allotment of data use (single lines plans are available, as well). The monthly price increases based on the number and type of devices you add to the plan and the amount of data that you elect to use.
  • As a CDMA carrier, Verizon's international coverage is limited to a handful of countries, but it offers dual-mode CDMA/GSM handsets.
  • Verizon offers prepaid plans.
  • Verizon announced Edge, its early upgrade program, in July 2013. You buy a new phone without a down payment, but you're on the hook for 24 monthly payments before the handset is really yours. Also, Verizon limits you to one upgrade every six months and you have paid off 50 percent of the price of your handset before you can trade it in for a new device.

AT&T

AT&T is the second-largest wireless carrier in the United States after Verizon Wireless. Today, AT&T has an extensive lineup of GSM devices, and a large 4G LTE network. The current company came to be in 2007 when Cingular Wireless, which acquired the original AT&T Wireless in 2004, changed its name to AT&T.

Things you should know about AT&T:

  • Like Verizon, AT&T has shared plans with data tiers for smartphones customers, but customers can stick with an individual plan if they prefer.
  • As a GSM carrier, AT&T offers extensive international roaming.
  • AT&T offers prepaid and family plans through its Go service and through its Cricket subsidiary.
  • AT&T Next allows customers to upgrade once every 12 months. There's no option for a down payment and you'll pay off your handset over the course of 20 months (to determine a monthly payment, AT&T divides its total cost by 20). When your year is up you can trade in your phone and start the process again. On the other hand, you must pay off your phone completely if you leave AT&T before your finished making those 20 payments.

Sprint

Sprint was the first carrier to offer a 4G network through WiMax technology, but it has since transitionted to LTE. Sprint carrier offers handsets of all stripes. The name Sprint first appeared in 1983 after Southern Pacific Communications Company merged with GTE.

Things you should know about Sprint:

  • Sprint continues to offer unlimited calling and data plans. On July 11, 2013, the carrier unveiled its Unlimited Guarantee, which promises that the monthly price of your service plan will not change for the life of your line of service.
  • Its international CDMA coverage has a smaller footprint than GSM, but Sprint has dual-mode CDMA/GSM handsets.
  • Sprint has "Framily" plans that let you share service between up to 10 people. Unlike some other family plans, the more people you add, the cheaper the monthly fee is for each person. Prepaid service is available through Sprint's Boost Mobile and Virgin Mobile subsidiaries.

T-Mobile

After a failed merger with AT&T in 2012, T-Mobile remains the smallest of the big four U.S. carriers. It now operates an LTE network and after first introducing an HSPA+ "Faux G" network that delivers LTE-comparable speeds. T-Mobile was the last major carrier to sell the iPhone and it was an early leader in Android. Compared with the other major carriers, its home network is less prevalent in rural areas.

Things you should know about T-Mobile:

  • In March 2013, T-Mobile changed its service plan model . Most importantly, it did away with contracts completely, which means that you can end your service at any time. Customers get unlimited voice and text messaging service, and on top of that can choose from a variety of data packages. Though total data use is unlimited, T-Mobile prices its plans by how much 4G data you can use each month. Also, T-Mobile no longer offer subsidies for its phones. You can either pay full price for the phone up front or you can "finance" your handset by paying monthly installments for two years.
  • As a GSM carrier and a subsidiary of Germany's Deutsche Telekom, T-Mobile has extensive international roaming.
  • T-Mobile carrier offers no-contract family plans .
  • T-Mobile kicked off the early upgrade trend by announcing Jump on July 10, 2013. Available only for customers who are paying off their handset in installments (so if you paid full price, you're out of luck), Jump requires an extra fee of $10 per month, which also works as an insurance policy. You'll buy your device in 24 monthly payments, but, unlike AT&T and Verizon, you start with a down payment. After you're in the Jump program for six months, you're eligible for their first trade-in. You'll have to make another down payment on your new handset, but the process starts again at that point. Note, however, that you can upgrade no more than twice in a 12-month period.
