This looked promising but even though it allowed me to enter my number and hit the "Save" button, it did not actually save it. Still stuck with the new SIM phone number as apposed to my exsting phone number..... any ideas?

Literally tried everything in the book from resetting the settings to the whole phone settings absolutely nothing watched every vid I could read everything I could nothing like this problem came left field

I had the same issue they’re gonna send me a refurbished phone after I had to reset it because it still wasn’t working but I just canceled it because I thought that my phone was working everything but the phone number is working. I’m having the same issue.

This Phone Number Cannot Be Used by iMessage and

FaceTime

You must have a SIM associated with an Apple device for (my number ) to be used for iMessage and FaceTime.

for two days now no solution please help me

I have tried these steps several times, and unfortunately am still getting the message that the sim must be associated with an apple device. I have verified the number several times as well. Not sure what to try next.

None of this works. The caption phone number, email etc does not exist in settings. It worked for some of you by mere luck. Apple never answered this question. I think they have no idea how to fix it, only focusing on how to get money

They are both connected to each other is what I found out. From an error occupied during activation I found out that it could have to do with the back up, but I dont have any space so I found out next that my phone number also is displayed as unavailable. I tried contacting my carrier/ network provider but they said that the problem wasn’t related with them. I don’t know what to do honestly.

I think I just had my Apple ID set as my contact method, since I didn't have phone service on my device.

I have the exact same message being displayed as the moderator has posted. I’m able to make cellular phone calls, use cellular data and receive an SMS. However, I am not able to send an SMS.

SMS is indeed a carrier feature.

I'm sorry, it's been a frustrating day. I didn't see you weren't replying to OP but a different issue brought up on the thread. My bad

I wish my fix was that simple, this is the only device I have associated with my account
