iPhone not blocking calls/emails/voicemails after iOS 26.4

iOS 26.4 is now preventing iPhone from Blocking unwanted phone numbers, email address and voicemails.


Ever since installing iOS 26.4 on my iphone 17 pro max on March 25, 2026, iPhone will no longer block sender of calls, voicemails or emails...


Before the recent iOS update, one could swipe left on the respective phone number and select either "Block" or "Block and Report Spam" - to be clear, these steps and options are still appearing on my iPhone. However, before the update, if you selected one of the aforementioned block options, then the respective phone number, voicemail or email would then display "O-slash" symbol to indicate that the respective phone number, etc. had been successfully blocked. One could also swipe left again on the phone number/voicemail/email and then also confirm that the phone number, etc. had been successfully been blocked by seeing the option to "Unblock" the respective phone number, etc.


Now, after the iOS 26.4 update, the O-slash symbol does not appear and the option to Unblock does not appear either - the "Block" option continues to appear indicating that the respective phone number, email address or voicemail is still not blocked.


As I stated above I'm using an iPhone 17 pro max with iOS 26.4; all apps are current. Ive restarted my device several times and made no changes to any of my settings before or after the iOS update.

Thank you for the feedback. I waited for an iOS update to resolve the problem but unfortunately it didn’t happen. I was able to restore the block function by going to Settings / General / Transfer or Reset IPhone / Reset / Reset All Settings. Keep in mind when selecting this option you will lose all current settings and all the numbers previously blocked. I lost over 17,000 but I’m back in the game of blocking trash calls.

It appears that there are now limitations on the maximum number of blocked calls that are allowed. After starting from scratch the function stopped working once I got to 3000 blocked calls. I’m not sure if this will be addressed in future updates.

You do understand that most spammers spoof numbers and change them more often than you blink? Blocking them is largely pointless.

I have the iPhone 13 Pro Max series and just did the update right now of 26.5.2 - for the past several weeks I have not been able to block phone calls or emails and I was hoping this update would fix it, but it has not. I have tried to reset my phone. I’m not interested in taking numbers and manually having to enter them, I should be able to just go into that call or email and block it. Please advise as to next steps.

APPLE needs to hire you!! I asked a dumb question this past week of how to add a number to an already blocked number BUT I didn't realize you could add a TON of numbers to the same contact. I thought you were only allowed maybe a cell, landline and one other. SO.... I took your advice, and started adding a boatload of spam numbers to one of my blocked spam numbers and have about 50 blocked numbers on one spam contact. THANK YOU!!!!!!! It DOES WORK : ) btw I'm FLAGIRLFROMCALI in case anyone sees my stupid question.

When is Apple going to restore everyone’s phone with our “Block” service again! This is a security issue for me and also to block all the unwanted politcal and spam calls/texts we get everyday - 100’s of them.

Blocking such things actually accomplishes very little as 1)political messages may be protected and 2)actual spammers change their spoofed numbers regularly.

WHAT IS APPLE GOING TO DO ABOUT THIS‼️‼️‼️‼️‼️‼️‼️‼️

This is a user-to-user forum. We don't have any special, super-secret knowledge of Apple's future plans. So please, stop screaming at us.


Also, Apple doesn't read here for feedback or suggestions. You can, however, let them know your thoughts here:

I updated to latest 26.6 and unblocked all my blocked numbers and for now there blocking again

Great to hear! That is the recommended approach and where others have found success. Blocking works for me and I am on 26.6 with only about 10 blocked contacts. Thanks for the update.


At this point, I would recommend users who have not found success to create a new post, since this thread is 4 months old with a completely different iOS version. That way you can post screenshots of what you are seeing and have support for your individual case instead of just a me too post on another thread.
