New iPhone XS Max “Number changed to Primary” notification in iMessage

Restore through Itunes , set up as new , sign into imessage with apple id and facetime ... test messages . should work.

Hey hixxup79 you’ll have to delete all your messages and start fresh for that to completely stop :( it really sucks that’s the only way.

Hello, I bought my brand new iPhone XS in April 2019. I also don't have a dual sim. I called Apple and they said it is a bug and they are investigating it. I told them that they have been investigating since September 2018 (cause I read a lot of complaints of the web). She said that they didn't find a solution yet and to make sure I update always my IOS. My problem is that when I start a new message, I choose the contacts, then I use the effects (bubble, balloons, etc.) then I press the blue arrow to send it. It gives me a pop up at the bottom saying: Number not available. Which number would you like to send the message with? PRIMARY or CANCEL. I tried primary then the message is sent. I tried cancel, it didn't send. Then I went in my message and deleted the message. What works for me right now is this: When I want to send effects with Message I need first just to type a phrase like: Hello. Then once that contact is in message then I go in effects and choose bubbles or confetti then it sends it (it gives me the impression that Effects doesn't recognize Contacts). It does the same thing with the giphys. I don't have 2 telephones and I'm quite upset cause I have been saving money for this brand new iPhone XS and already there is a bug. I called also my carrier Telus, and she told me that in the iPhone there is a SIM card and an E-card implemented in the iPhone itself. She said that they are not offering yet this service but Rogers does. It doesn't make sense that Apple is sending this option and when I look under Cellular - Telus - there is no option available like Primary and Secondary telephone - only Telus. I'm getting tired trying to figure out what it is but all of us is doing the same thing cause it is not functioning like it supposed to function. Apple is taking long to resolve this problem and the girl told me they don't know when it will be resolved. I'm just sad cause this was a gift to myself for my birthday July 1st and I saved my money for one year and was so happy. But when using iMessage and effects, it's like I got hit on the head and I am disappointed. Hopefully Apple will do something soon. We just need to be patient and believe it will be resolved. Sorry about my writing - I am French and my second language is English. I did my very best to explain my problem - you are not alone with this problem. Hope this help.

NOTE: I also deleted the two or three SMS threads that had the problem in the process.

God please fix this!! Disabling FaceTime and Messages for a bit and turning them back on resolves it for a while, but it always comes back. I only have one stupid sim. This should not be a problem.

I just figured it out for my situation (after deleting my a "turned-green" group message thread and trying to start over, which didn't work, unfortunately).

All I had to do was go into Messages on my Mac and send a message from there in the same group, and it resumed allowing my to send iMessage messages (blue bubbles) on my iPhone in the same conversation.

Hope this helps!

I have the same problem! I’ve tried resetting iMessages and it didn’t fix it. Is it something they can update in the next iOS update? It doesn’t seem to affect any of the messages it’s just annoying

Oh no! I’m not sure to be honest because mine has been seemingly fine since re-enabling iMessage last night. I’m not sure what the issue is to be honest, I didn’t have the problem until I had AT&T set up my new Apple Watch 4 in cellular so I wasn’t sure at first if the issue was with that or not because didn’t use the phone until I got that’s set up because I pre-ordered them together.

Alright. I have this issue too, and have been working with senior engineers at support for 2 days! I restored and that didn't do anything. And followed some other suggestions on here. They said it's a known issue, I think they are just realizing how big it is. Andrew, the guy helping me said they are working way overtime on this. Will report back with updates.

Their method does not work! I am on the phone with Apple right now and have been working on it for a week with them. It's not an easy fix, and they will probably end up sending me a new phone because I'm starting to get mad.

HI, I am having the same issues. Even with the second IMei number. I want to know if it is possible someone else is getting my texts or can view my screen from another phone. I feel someone else has access to it. is it possible?

Using Dual SIM with an eSIM - Apple Support

You have to set up the primary and secondary numbers on the XsM
