iPhone 15 Pro: Apple Pay setup fails, NFC issue

Hey everyone, I'm hoping someone has seen this specific issue before.

I haven't been able to use Apple since upgrading to my new iPhone 15 Pro from an iPhone XS, and I'm stuck between an expensive repair and a hopeful software fix.

The Main Problem:

Whenever I try to add a new card to Apple Pay, I get the immediate error: "Could not set up Apple Pay."

It fails instantly, before the card entry screen even appears.

For Context (NFC Failure):

I think the root cause is a bad NFC connection. My general NFC scanning functionality is also broken:

* Apps freeze completely after I try scanning an NFC tag.

* The NFC only worked briefly one time before failing permanently again.

The Big Conflict:

I ran a remote diagnostic with Apple Support, and they flagged a "Sensor Issue," suggesting I need a hardware replacement.

However, since the NFC actually worked that one time and the apps are freezing (which feels like a software process getting stuck), I suspect this could be a firmware or driver crash that’s making the diagnostic tool think the sensor is physically dead.

Device Info:

* iPhone Model: iPhone 15 Pro

* iOS Version: 26.1

Before I commit to an expensive out-of-warranty repair, has anyone successfully fixed this specific "instant setup failure" (that was diagnosed as hardware) with a software solution? Does this maybe have something to do with the general instability of iOS 26?

Thanks for any help!

Please follow this path,

Then it would appear you have ruled out any software issue and with the diagnosis of a sensor failure, it would indicate a hardware failure is the likely problem.

You can further test the NFC reader on the iPhone if you have a NFC tag to check and that can also be confirmed at an Apple Store.

Hey, thanks for the reply!

Sorry I forgot to mention, but I did just that. I reinstalled the OS clean using my Macbook. That didnt fix it..

I also am in a supported region, as I said, it was working fine on my old iPhone XS. I'm not using a VPN, and I do have a passcode set up.

It also can't be a problem with the bank since it was working fine on my old phone, plus the error popup comes before I can type in any card details. It's literally the first thing I see after pressing the plus button on the wallet app to add a new card.

That's it. Hope you can help me further :)

Any software solution would come from a Factory Reset of the phone, and would recommend using a computer to perform an archived backup first. Using a computer is the only way to reload the OS. If you do not have a computer, you can borrow one or use one at an Apple Store where they will assist.

Other reasons why you would see the Could Not Setup Apple Pay error are:

Not is a supported region? Are you using a VPN?
Not having a Passcode set up on your device.
Bank does not support Apple Pay.
