Google Pay with iPhone 6 is not working anymore

The iPhone 6 will not support an iOS higher than the iOS 12.5.4 that is currently installed on the device. It does not have the hardware needed. That device is 7 years old. It is no longer supported. That is why Google is changing what it supports.

Gpay is NOT an Apple product or service.

Go complain to Google.

"All iPhone 6 and 6s users will have this problem"......

If you want to keep complaining; that's fine by me, but......... get your facts straight.

All iPhone 6s users are on iOS 14.7.1 by now (because of the hardware).

They even get iOS 15 when it is released.

You can read the reason in the screenshot.

if you want to use it.......... you have to buy a new(er) iPhone.

If your iPhone is working fine..... keep using it.

By the way..........

It's not Apple who wants you to buy a new iPhone because of Google Pay......... It's your bank.

Talk to them.
