Apple Intelligence missing in iPhone 15 Pro Max after iOS 18.1 update

How can get the intelligence feature in iPhone 15 pro max ends in ch/A

• If your model number of the phone ends in CH/A, then it is intended for China and will not have the features.
• You also need to set Siri Language to English, not just device region.

You don't. Phones purchased in China aren't eligible at this time.

I didn’t change region. I left mine as UK, set the preferred language to English US and then set the Siri language. A button to join the waiting lists appeared after this in the AI & Siri setting. I may have had to restart to get this.

Same issue, i use 15 pro, i updated 18.1 but I didn’t fine any intelligence option in my settings, i already changed my region and language also

Have you tried restarting your iPhone since you changed to English US in both Language & Region and Apple Intelligence &Siri?
