PSA: Apple's 14.7.1 Software Update made my iPhone 12 Pro unusable

10 points by akouri 4y ago ↗ HN

I am on AT&T with an eSIM. I updated to 14.7.1 and am getting "SIM Failure" when I try to do anything. Cannot connect voice or data.

I have tried: - Going to AT&T store and getting a physical sim to replace my current eSIM (no dice) - Resetting network settings - Resetting entire phone

Do NOT update to 14.7.1 if you are on AT&T and have an eSIM! Save the hassle!

..What did Apple say?

It’s currently under investigation by their engineering team. Funny enough I took it to the apple store and two other people were in there with the same issue. They replaced my phone.

I am guessing the update somehow fried the baseband chip.

Not a problem for me.
