These terms cover bestcellular.com, its free tools, and the Best Cellular plugin in ChatGPT. By using them you agree to these terms. If you do not agree, do not use them.
Who publishes this
Best Cellular is published by Assertive Holdings, LLC, a Colorado limited liability company. “M. Curtis McCoy” is a registered trade name of Assertive Holdings, LLC.
What Best Cellular is
Best Cellular publishes information about US phone carriers: where to find an account number, how to get a transfer PIN, who to call, and which network a carrier runs on.
Best Cellular is not a wireless carrier. It does not sell phone service, issue account numbers or PINs, or act on your carrier account. It is not affiliated with any carrier. You get your account number and transfer PIN from your own carrier. Carrier names and marks belong to their owners.
Accuracy
We check each entry against the carrier’s own published support pages and date it. Carriers change their steps without notice. Confirm with your carrier before you act on anything here. The information is provided “as is,” with no warranty of any kind.
Your account details
Best Cellular never needs your account number, transfer PIN or phone number, and its tools and plugin never ask for them. Do not type them into the plugin or into any chat.
The ChatGPT plugin
The plugin is free and read-only. It looks up published information and does nothing on your carrier account. ChatGPT is a product of OpenAI and is governed by OpenAI’s terms. What the plugin receives and keeps is described in the Privacy Policy.
Use of the site
Use Best Cellular lawfully and for your own information. Do not overload it with automated requests, interfere with its operation, or present our content as carrier-issued.
Affiliate links
Some links on Best Cellular are affiliate links. See the Affiliate Disclosure and how we make money. Commission never decides what we publish.
Retired wireless service
Best Cellular’s former wireless service has ended. Its service-era terms, billing, warranty, return and network documents are retired and create no rights or obligations today.
Liability
To the fullest extent the law allows, Assertive Holdings, LLC is not liable for losses that result from relying on information here, including a rejected or delayed number transfer. Nothing in these terms limits liability that cannot be limited by law.
Changes and governing law
We may update these terms. The date at the top shows the latest version. Colorado law governs these terms.
