iOS 26.6 beta 1 arrived today, and with iOS 27 right around the corner, it’s unsurprisingly very light on changes. But one difference was discovered by Aaron Perris: a new alert that appears in iOS 26.6 when you try to block one contact too many.

Apple doesn’t publicize this information, but iOS quietly enforces a limit on how many contacts you can add to your ‘blocked’ list.
Though the vast majority of users likely never hit that limit, iOS 26.6 adds a new alert for the few that do.
Here’s what it says, per Aaron Perris:
Blocked Contacts Limit Reached
You’ve reached the maximum number of blocked contacts. To block additional callers, remove a blocked contact in Settings.
This popup was uncovered by Perris as he reviewed the updated code Apple shipped in iOS 26.6 developer beta 1.
Here’s a screenshot of his discovery:
This is an extremely minor change. It’s only noteworthy because it does represent something new in iOS 26.6, a release that so far appears entirely void of other user-facing updates.
Have you ever hit the max limit in iOS for blocked contacts? Let us know in the comments.
