Check coverage before you port
We have not confirmed which national network EarthLink Business uses, and we do not guess. Ask them before you port, then check that network’s map: 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.

Questions about EarthLink Business
Can I keep my phone number when I leave EarthLink Business?
Yes. Federal number portability rules let you take a working number to a new carrier. EarthLink Business cannot refuse the transfer or charge you to release the number.
Should I cancel EarthLink Business before I port my number out?
No. Cancel first and the number is released, which ends your right to move it. Keep the EarthLink Business line active until the new carrier confirms the port completed.
How long does a port out from EarthLink Business take?
Wireline and VoIP transfers run longer than wireless. Plan on a few business days once EarthLink Business has validated the account number and PIN.
Does EarthLink Business run on its own towers?
Not confirmed. EarthLink Business has not published which host network carries its traffic.
