Is iOS 18 available to the iPhone SE?

What generation of iPhone SE do you have?

• iPhone SE (1st generation) can run iOS 15, but cannot run IOS 16 or higher.
• iPhone SE (2nd generation) and (3rd generation) can run iOS 17, and will be able to run iOS 18 when it comes out (according to the compatibility list on the iOS 18 Preview page).

Whenever it does get released to the public, Apple has only announced support for the 3rd gen iPhone SE model. Your device will tell you when an update becomes available.

How to update for IOS 18 in SE models?

Assuming a compatible device, wait until iOS 18 is released later this year, then install it as with all other updates.

iOS 18 will not be available for another 2-3 months. When the update is available, it will appear on your iPhone.
