My number shows “unavailable for sharing” in the security section and it can not be used for message or facetime.

I have the same issue. I do recruiting and reach out to people who fill out forms looking to work from home. I guess someone reported me as spam. I have had the same issue for about three weeks to a month! Thank you so much for sharing the solution.

Aren’t you blacklisted everywhere? Guess when you do the spam calls to others, it finally catches up. 👍🏻

I have fixed this twice now for persons following these steps:

1. Sign out of FaceTime

2. Sign out of Messages

3. Power Cycle.

4. Sign out of iCloud Completely. (This is the main thing)

5. Power Cycle.

6. Sign back into iCloud.

7. Fixed.

This was exactly my issue! I got a new device/phone number for work. And immediately after setup, it said iMessage activation was unsuccessful, but only to the new phone number not the Apple ID with my email. After a week of working with the carrier and spending hours in the Apple store, they only said they would try to escalate the issue but couldn't identify the problem after trying all of the troubleshooting that others have cited, changed out sim and even tried a new Apple ID. I came to this forum and called Apple, asked to check for blockages the first rep couldn't see anything, then was escalated to a Sr. Advisor who found the number was on a block listed and removed it. Everything was reconciled after 5 minutes! Thank you so much for this. Everything is now syncing.

I have the same problem which suddenly started two days ago, when I got the message I had to sign in with my Apple ID to get messages on my computer. When I did that I was logged in for a few seconds then it logged me out. I have spent maybe 7 hours or more talking with Applecare, rebooting in safe mode, going to the Genius Bar, talking with a tech support for apple again...They did a clean reinstall on my computer..nothing. All a bit waste of time. Then I was told it was not a problem with the computer but that the phone was not connected to the iMessage server. Now I am supposed to wait 24-48 hours to see if my phone becomes linked to my carrier, T Mobile and left iMessage on. Feeling pessimistic about this problem. FaceTime is also unavailable.

I had the same issue. I spent hours on the phone with AT&T and Apple. I came to this site and was able to fix it in 5 minutes. My number was on a spam list or blacklisted. I called Apple again and they removed it from the list and it is now fixed.

I had the same problem. I spent four hours at the Genius Bar. I read that sometimes numbers are blacklisted as spam. Mine was not. I called Apple support. They said my number had somehow become unregistered. It would work in 24 hours. I was skeptical, but it was the fix!

My number is unavailable for sharing and unsuccessful when trying to activate on the settings.

did you call Apple?

My phone has the same issue. I too have performed all the troubleshooting steps. I welcome any suggestions to get this issue resolved.

I can’t reply until I hear some answers. I want to hear the reply for my phone says unavailable for sharing

Looks like mine is doing the same right now. Any solutions?

How do I fix this

Thank you SO MUCH!!

I’m unable to share documents with my apple I phone and I need to fix it because I have been share stuff for years all of a sudden today it’s not allowing me to share
