Unable to send MMS messages on iPhone 12 pro

iMessage failure to send the message

displaying”number is not registered in

iMessage despite previous messages

still in the log, this happened to my

old iPad mini. Weeks ago Apple had

me signed for iMessage ...that worked

for couple of days only.

this sending failure occurs when sending

to some people, not all,

whenever their name or phone number

entered the top of the screen turned

green, their name and number turned

to red, thanks for advice.

iphone 📱 12 is ok 👍 now.

Anything having to do with MMS is still a carrier problem, not an iPhone problem. You must contact your carrier’s tech support and have them either fix it, or reprovision your account. You may need help from a tier 2 tech to do this.

I have same problem in my iPhone 12, able to receive group messages and pictures from android users, but unable to send group messages or picture to android users. Tried several steps with the provider, no fix yet. Any help is appreciated

This started not working for me today. Wife has an Android. Not sure if that matters. I've sent her pictures this way 100 times today. All software is up to date. 11 Pro Max user here. I even reset network settings. Nothing works. I'm trying to send from Messages on MacOS

Note that you must have cellular data turned on for MMS to work.

If it just happened it might be a carrier outage. You can check this crowd-sourced site: Down Detector - outages and call the carrier’s technical support.

Cellular data is turned on. I spent 45 minutes with phone carrier last night who confirmed MMS is enabled. I signed out of iCloud and signed back in. Resynced. Did that twice. Restarted my MBP twice. Nothing. This morning it is working again. I don't know what happened I believe it is an Apple/Big Sur issue.

Yes, but I don't know how or why. I signed in and out of iCloud and resynced everything and it started working. Note, it was not working on MacOS Big Sur, but was working on the iPhone, so I think it is Big Sur related. The next day it started working.

Hi Kylie

I brought my son the iphone 12 pro for xmas and after discovering he can't send or receive picture messages we have done some research.Now I purchased his iphone with the esim at first we thought this was the issue.

So I had optus send me out a physical simcard and still can't send pictures or receive.

Next was told to update apple software thats done , MMS is turned on like we were told to do.

So I decided to try my simcard out and put it in the iphone 12 now my simcard is 4G so I sent a picture message between my sons iphone 12 with my simcard to my other sons phone and it worked .

So now I have worked out if the simcard has 5G on it you won't be able to send or receive pictures messages until the network company come up with a solution.

My solution around this is I will be contacting optus again and asking if my son can have a 4g simcard then his problem is solved.

If you have access to a 4g simcard off a friend ir family member that you can run your own test you will see :)

Hope this helps

This doesn't help. They just said it is enabled in settings. I have the same problem...

You need MMS enabled by your carrier. and in your Settings. See the Pic below

Same issue even after the update. All the group messages are in separate form. MMS is enabled and called my carrier to double check. Hope next update will fix this.

This shss is not working!
