After 16.5.1 update iMessage wont activate phone number

After 16.5.1 update iMessage signed out of my phone number and it will not activate again.

Please do not try to send me this: If you can’t turn on or sign in to iMessage or FaceTime - Apple Support

I have tried everything and it is not working. Meanwhile my carrier sent dozens of international messages, all of them charged :(

Just admit that problem is on you side and fix it!


iPhone 14 Pro, iOS 16

They literally tried everything to solve this issue. In the end they said me to send a text message to a number 48369 with a text HELP. A message was not delivered. According to them it means problem is on my provider. I contacted my provider then. This number is not supported outside US and Canada, so obviously it could not be delivered.

They think it is a problem with an international text message to activate iMessage. Trust me, it is not. I sent dozens of them since last week. Everything worked fine until 16.5.1 update. After that - it is not.

Seems like many people have this same issue.

What is more - activation message had never been charged before. I am on supported carrier by Apple. Now - it is charged.

Hope they will update iOS soon. I found that 16.5.1 was released to fix a critical iMessage security issue. Obviously something went wrong, cause now it does not work. E-mail ID works fine. Phone number ID nah.

That link you posted say to contact Apple support after 24 hours.

And what did Apple support say when you contacted them?
