Check coverage before you port
TPO Mobile runs on the T-Mobile network, so the coverage you get at your address is T-Mobile coverage. Check it on T-Mobile’s own coverage map before you start the transfer.
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 TPO Mobile
Can I keep my phone number when I leave TPO Mobile?
Yes. Federal number portability rules let you take a working number to a new carrier. TPO Mobile cannot refuse the transfer or charge you to release the number.
Should I cancel TPO Mobile before I port my number out?
No. Cancel first and the number is released, which ends your right to move it. Keep the TPO Mobile line active until the new carrier confirms the port completed.
How long does a port out from TPO Mobile take?
A simple wireless transfer usually completes within one business day once the new carrier submits the correct TPO Mobile account number and transfer PIN.
Does TPO Mobile run on its own towers?
No. TPO Mobile is a reseller riding on the T-Mobile network.
Does TPO Mobile charge a fee to release my number?
No. A carrier cannot bill you for porting a number out. You may still owe a final bill or an unpaid device balance, and that is separate from the transfer itself.
What happens if the TPO Mobile account number is wrong?
The port request is rejected and the new carrier resubmits it. The number stays on TPO Mobile in the meantime, so nothing is lost — it only costs time.
