About Best Cellular
Operated by Assertive Holdings, LLC · Last reviewed October 25, 2026
Best Cellular is a free reference for people who want to leave their wireless carrier and keep their phone number. We publish the account number, transfer PIN and port-out steps for every US carrier and MVNO, and we say which of the three remaining networks each one actually runs on.
No account. No sales call. No form standing between you and the number you came here for.
What is Best Cellular?
Best Cellular (BestCellular.com) is a free, independent reference for US wireless carriers. It publishes the account number, transfer PIN and port-out steps for every US carrier and MVNO, active or shut down, and shows which of the three national networks each one runs on.
- Who uses it: retail wireless stores, prepaid dealers, cellphone repair shops and anyone moving a phone number.
- What it is not: a wireless carrier. It sells no service, activates no phones and runs no stores.
- Who runs it: Assertive Holdings, LLC. Managed by M. Curtis McCoy.
Not a carrier. The reference for leaving one.

What Best Cellular publishes
The wireless industry consolidated down to three networks: AT&T, T-Mobile and Verizon. Everything else you can buy is a brand renting space on one of them. Which network your carrier uses decides your coverage. The logo on the bill does not.
Almost nobody leads with that, so we do. Every carrier page answers four questions in the first screen:
- Where your account number is, and what format it takes
- How to get your transfer PIN, including the ones carriers hide behind a phone call
- Which network the carrier actually runs on
- The exact port-out steps, in the order that does not lose your number
Alongside that: a plain-English guide to switching carriers, a page on what to do when a port gets rejected, and carrier unlock policies and an eligibility checker, which change more often than any other fact on this site.
How the information gets verified
Primary sources only
Every carrier page is checked against the carrier’s own documentation — published support pages, account terms and porting policies. We do not copy other comparison sites, which is how a wrong account-number format spreads across twenty domains and stays wrong for years.
The right we document on every carrier page, keeping your number when you leave, is federal law. Best Cellular follows the FCC’s own guide: Porting: Keeping Your Phone Number When You Change Providers.
Dated, and corrected in public
Carriers change their port-out process without announcing it. Pages carry the date the facts were last checked. When something is out of date, tell us and it gets fixed — corrections are not buried.
No paid placement, ever
No carrier can buy a position, a rating, a recommendation or a review on this site. No carrier sees a page before it publishes. If a carrier’s port-out process is bad, the page says so.
How this site makes money
Some links to carriers on this site are affiliate links. If you sign up for service after clicking one, Best Cellular may earn a commission. It costs you nothing extra, and it is how the research gets paid for.
Three limits on that, and they are not negotiable:
- Commissions never change the data. Account numbers, PINs, port-out steps and network assignments are facts. They are not for sale.
- Commissions never change the order. Where we recommend carriers, they are filtered by the network you actually need and then sorted by price — not by what pays us.
- We tell you which carrier pays us, on the page where it pays us. Not once in a footer nobody reads.
This follows the Federal Trade Commission’s Endorsement Guides, 16 CFR Part 255. The full statement is on the affiliate disclosure page.

What we will not do
- We will not ask for your account number, your transfer PIN, your Social Security number or your carrier password. Nobody at Best Cellular needs them. Anyone claiming to be us and asking for them is not us.
- We will not sell your information. See the privacy policy.
- We will not publish a carrier recommendation on a page where we cannot confirm which network that carrier runs on.
