iPhone 17 Preorder (from Apple) Issues with Boost

I’m not with Boost but it sounds like an issue with their systems not communicating correctly with Apple’s (which is something they would need to have their IT address not Apple) or there may be an issue with the provisioning for your account (again would sound like something that they would need to address). Those are just guesses though. You could contact Boost again and ask for a supervisor that can hopefully delve deeper. It’s possible you are speaking to 3rd party contracted call centers that are limited in what they can actually do or see

ugh! Ive been dealing with this for the last week.. I’ve called boost’s customers service a total of 7 times.. it’s almost as if they want to force the customer to finance through them… NOO I want to finance my phone with apple.. I’m going to cancel my boost line tomorrow and switch over to another carrier

I just came here to say I'm having the exact same issue and exact same support experience in October 2025. I'm trying to finance an iPhone 17 for a family member who is on a Boost contract, and when we go through the checkout process with Apple Card Monthly Installments, we must go through the carrier validation process (Phone Number + ZIP --> SMS --> Verification Code --> Validation). This validation fails, with slightly different response depending on whether I checkout on apple.com or the Apple Store app.

apple.com: Account not supported. We've run into an issue completing your iPhone activation. Please call Boost Mobile at so they can resolve it.

Apple Store: The mobile number you entered is not active. Please try again or contact Boost Mobile.

We've contacted Boost, who suggested nothing was wrong with the account, and said to contact Apple for assistance. We then contacted Apple, who suggested that the error response comes from Boost, and that we must work with them to resolve it.

We will certainly be contacting Boost again tomorrow, but unfortunately we don't yet have a solution for this either. Just wanted to share that this is still an end-user experience a month after the original posting here.

Just wanted to ask if you ever solved the issue? I'm having the same problem, I want to get 3 phones from apple but have boost mobile and it won't let me it keeps giving "Account not supported", thanks in advance

I wanted to add for future people with the same issue, they said it's because we have a prepaid plan, we need to change it to postpaid and then we are able to finance thru apple, finally someone told me a real answer

Were you able to get a new phone? I “upgraded” my plan to a post paid with boost bc I had some “grandfathered” plan… and once that was done it still didn’t work for me. I was given several excuses from different boost agents, I gave up and just switched to T-Mobile.
