you must have a sim associated with an apple device for to be used for imessage and facetime

Exact same problem on an iPhone 11Pro. Means I can't activate Facetime or iMessage via the phone number, which was working only a few days ago. Also, I am not receiving texts for authorisation etc. from Apple when sent, but it receives personal texts from SMS etc. fine.

Such a pain!

Thank you but already did , as i mentioned before.

no problem with carrier, as long as using android phone works just fine. But using iphone, sms sending is no longer available. I think it has to do with Sms center number SMSC, which cannot be set manually or eitherways on iphone.

Same issue with my iPhone 13 Pro max, no problems until today. Can still make calls, send texts etc, just iMessage and FaceTime not working

Tried updating to 17 to see if that helped, no luck

Seems like somethings going wrong at Apple

i swapped sims yesterday and it's telling that the sim is no associated with an apple device, it worked yesterday but i removed the number as i am now waiting for my SIM with my old number so i have now tried again - and nothing, same error message over and over, tried a new SIM and it worked but i want to make sure i can use my old number when that sim arrives tomorrow? Any ideas, it's driving me mad

Having the same issue on iPhone 14 Pro! iMessage and FaceTime give an activation error and will not verify my number. I just bought this phone 2 days ago and number was ported over yesterday to Verizon. I spent all of yesterday trying all suggestions such as restart device, log out of Apple ID, add number to iCloud, etc. I also removed the number and signed out of my old iPhone. Only thing I haven’t done is reset esim. My device is eSIM only. I reached out to Apple and they said this was a “common issue” and advised me to wait 48hr for the problem to resolve itself. I eventually gave up and a couple hours later I tried toggling it on and to my surprise it activated. I could FaceTime, send iMessage, etc for the first time. I started feeling relieved and maybe thought I was overreacting but a couple hours after that it disconnected again lol. And this time no matter what I do I cannot get it to turn on again. This is so incredibly frustrating especially since it now connected once and just won’t connect again. Really hoping this is solved soon

Having the exact same issue on my iPhone 15 pro, did you find a solution?

SMS is indeed a carrier feature

iMessage is not a carrier feature. iMessage is not SMS. SMS works. iMessage does not work. This is an apple issue, not a carrier issue

Thank you!

This approach worked for me; I think the magic touch was removing and reinserting the SIM card in my new phone.

Everything is now working as it should be.

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

No worries. Maybe take a little time away from whatever's bothering you if you can. I find it's always hard to do solid problem solving when I'm frustrated and angry.

I swapped to a new carrier last Friday, my number ported over Monday, I still have no iMessage or FaceTime, if I use a different sim it works so it’s not my device, if I put my sim in a different iPhone I get the same error so it’s definitely my sim, I have tried every guide I can find online … only thing I haven’t tried is a factory reset of my device but I can’t see what change that would make when it is the same result in other devices

The same message popped up when i tried to use my number for iMessage and facetime. Did everything i could. So use ny phone number as my apple id. And i have an esim too in my iPhone 13. The esim can be used for iMessage and facetime. But my primary phone number cannot be used for iMessage and facetime. Did everything. Please help

i tried all steps even swap my sim and still it does not verify my number.

i do not have my number associated to any other apple device.

shall I go with factory reset ?

one thing i noticed if i insert my brother sim with same carrier network it works but issue is only with my sim.

i did not get proper support from

apple someone can help 😔

I have had this issue for over 2 months now on my new iphone 15 pro. Its not a cellular problem as other people with the same cellular provider and the same plan are easily using imessage and facetime. I had a chat with the apple costumer care as well and i didnt get any solution. What might be the problem here?? please someone help me out with this….

Are you using a prepaid sim, if yes i can solve your problem. I was facing a similar issue since long and it was resolved recently after few upgradation from my own analysis. Let me know if you using a prepaid sim with a monthly fixed plan.
