Here is how to get your Boost Mobile account number and transfer PIN, and what to do with them when you move your number to another carrier.
Port-Out PIN
There is no self-serve option. Boost issues a port-out PIN for each line and the only documented way to get one is to call Boost Customer Care at 833-502-6678. Ask for the port-out PIN by phone number if you are moving more than one line.
Account Number
Boost does not publish an account-number field for port-outs. When the new carrier asks for one, give the 10-digit Boost phone number you are transferring, and give the port-out PIN in the PIN field. If the port rejects, call 833-502-6678 and ask the porting team for the account number on file.
Boost Mobile does not run on Sprint. It runs primarily on AT&T.
This is the single most out-of-date fact on the internet about Boost, and most comparison sites still have it wrong. Here is the actual sequence:
- Sprint sold Boost to DISH in 2020 as a condition of the T-Mobile merger. Boost stopped being a Sprint brand then.
- DISH (now EchoStar) built its own 5G network and moved Boost onto it, with roaming on T-Mobile and AT&T.
- On August 26, 2025, EchoStar announced it was selling its 3.45 GHz and 600 MHz spectrum to AT&T for about $23 billion, and moving Boost to a hybrid model.
- Under that arrangement Boost customers get primary connectivity from AT&T’s cell sites, keep Boost’s own 5G core, and retain access to T-Mobile as a secondary network. Boost’s own radio network was shut down on November 15, 2025.
What that means for you in practice: your coverage is AT&T coverage, with T-Mobile as a fallback. If AT&T is weak where you live, switching to another Boost-like prepaid brand on the same towers will not fix it. Check the network before you check the price.
How to port your number out of Boost Mobile
- Call 833-502-6678 and ask for your port-out PIN. Get one for every line you are moving.
- Confirm your phone is unlocked. Boost follows the industry prepaid standard — expect a waiting period from activation before it will unlock.
- Start the transfer from the new carrier, never from Boost. Give them the Boost number, the port-out PIN and your billing ZIP code.
- Leave the Boost line active until the port completes. It cancels itself.
Boost Mobile APN settings
Boost Mobile runs on more than one host network.
The Boost Mobile help center does not publish APN values.

Check coverage before you port
Boost Mobile 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.

Same towers, different bill
If you are leaving Boost, stay on AT&T coverage
Boost’s primary network is AT&T. These carriers run on the same towers, so your coverage does not change — only the price and the support experience.

Questions people ask about leaving Boost Mobile
Is Boost Mobile still Sprint?
No. Boost stopped being a Sprint brand in 2020 when DISH bought it as a condition of the T-Mobile merger. Sprint as a network no longer exists at all.
What network does Boost Mobile use in 2026?
Primarily AT&T, with T-Mobile as a secondary network, under the hybrid arrangement EchoStar announced on August 26, 2025. Boost’s own 5G radio network was shut down on November 15, 2025.
Can I get my Boost port-out PIN online?
Not according to Boost’s own support documentation. The only documented method is calling Customer Care at 833-502-6678.
Will Boost charge me to leave?
Boost is prepaid, so there is no early termination fee. If you financed a phone through Boost, that balance still has to be settled, and the phone stays locked until it is.
What happens to my Boost account when the port finishes?
It cancels automatically. Boost states this explicitly and warns customers not to cancel manually beforehand.
