Check coverage before you port
Cellular One uses more than one network, so your coverage depends on which one serves your address rather than on the brand on the bill. Check all three: Verizon, T-Mobile, AT&T.
Your right to keep the number is federal, not a carrier policy. The rule is the FCC’s: Portability: Keeping Your Phone Number When Changing Service Providers.

Can I keep my phone number when I leave Cellular One?
Yes. Federal number portability rules let you take a working number to a new carrier. Cellular One cannot refuse the transfer or charge you to release the number.
Should I cancel Cellular One before I port my number out?
No. Cancel first and the number is released, which ends your right to move it. Keep the Cellular One line active until the new carrier confirms the port completed.
How long does a port out from Cellular One take?
A simple wireless transfer usually completes within one business day once the new carrier submits the correct Cellular One account number and transfer PIN.
Does Cellular One run on its own towers?
No. Cellular One rides on more than one host network.
