Cell Phone Carriers: Which Network Each One Actually Uses

There are only three wireless networks left in the United States: AT&T, T-Mobile, and Verizon. Every other carrier you can buy from is a brand renting space on one of them. Which network a carrier uses decides your coverage. The logo on the bill does not.

That is the single most useful thing to know before you switch, and almost nobody leads with it. Below: who runs on what, what changed in 2026, and the account number and port-out instructions for every carrier we track.

Which network each major carrier runs on

Network Carriers and brands riding on it
Verizon Verizon, Visible, Total Wireless, TracFone, Straight Talk, Page Plus, Xfinity Mobile, Spectrum Mobile
T-Mobile T-Mobile, Metro by T-Mobile, Mint Mobile, Ultra Mobile, Google Fi, Tello, Lycamobile, TextNow, Simple Mobile, Walmart Family Mobile, US Cellular customers moved over since 2025
AT&T AT&T, Cricket Wireless, H2O Wireless, PureTalk, Boost Mobile
More than one US Mobile, Red Pocket, Consumer Cellular

Note how many of these are owned outright by the network they run on. Visible, Total Wireless, TracFone, Straight Talk, and Page Plus are Verizon. Metro, Mint, and Ultra are T-Mobile. Cricket is AT&T. Switching between two brands with the same parent changes your bill and almost nothing else.

Two things changed in 2026 that most comparison pages have not caught

Boost Mobile stopped building its own network

EchoStar agreed on August 26, 2025 to sell 50 MHz of nationwide spectrum, its 3.45 GHz and 600 MHz licenses, to AT&T for roughly $23 billion. The FCC approved the sale in May 2026. Boost now operates as a hybrid network operator: its own 5G core connected to AT&T’s network, with T-Mobile access retained. Boost’s own radio network is being decommissioned over time.

In practice, the fourth national network people spent six years waiting for is not arriving. If you are choosing Boost, you are choosing AT&T coverage.

US Cellular is being absorbed into T-Mobile

T-Mobile closed its acquisition of substantially all of US Cellular’s wireless operations on August 1, 2025. The brand is retiring in phases over roughly two years. Through 2026 some customers still bill as US Cellular and some have already moved. It matters for porting, because only your current carrier of record can release your number. Our US Cellular page explains how to tell which you are.

How to choose, in the right order

  1. Coverage first. Ask two or three people who live and work where you do which network they use and whether it works. Coverage maps are marketing. Neighbors are data.
  2. Then pick the cheapest brand on that network. Once you know the network, the brands riding on it deliver the same towers. A $15 plan and a $60 plan on the same network reach the same cell sites. What differs is deprioritization during congestion, hotspot allowance, and customer service.
  3. Check whether your phone is unlocked before you commit to anything.
  4. Get your account number and transfer PIN from your current carrier. Find yours in the directory below.

Step-by-step instructions for the switch itself are on our guide to switching cell phone carriers.

What “deprioritized” actually means

Carriers rank their own direct customers ahead of the budget brands renting space on the same towers. When a tower is busy, the cheaper plan slows down first. At 3am it makes no difference. At a stadium it makes a large one.

That is the honest trade you are making when you drop from $65 to $20 on the same network. For most people, most of the time, it is worth it. If you commute through congestion daily, it is not.

Questions about carrier account numbers

What is a carrier account number?
The identifier your carrier uses for your account in its billing system. A new carrier needs it to request your number.

How do I find my carrier account number?
Check your online account first. If it is not there, call support and ask specifically for the account number and transfer PIN for porting out.

Is the carrier account number the same as my phone number?
No. Some prepaid carriers derive it from your phone number, but they are different fields.

Can a carrier refuse to give me my account number?
No. Federal rules require carriers to provide the information needed to port out.

How long is a transfer PIN valid?
Commonly seven days. Some carriers expire it sooner. Request it when you are ready to port, not weeks ahead.

Common questions about carriers and networks

How many wireless networks are there in the US?

Three that own nationwide infrastructure: AT&T, T-Mobile, and Verizon. Every other brand rents from one of them. Regional carriers like C Spire and Appalachian Wireless own towers in their own footprint and roam elsewhere.

Will my phone work if I switch networks?

If it is unlocked and reasonably recent, usually yes. Phones sold in the last several years support all three networks. Confirm band support before you buy anything used.

Does a cheaper carrier mean worse coverage?

No. It means the same towers with lower priority during congestion. Coverage is identical. Speed under load is not.

Can I keep my number when I switch?

Yes. Federal rules require carriers to release your number. Port before you cancel, never after.

Which carrier is best?

The one whose network works where you spend your time, at the lowest price on that network. Anyone who answers that question without asking where you live is guessing.
