Running iOS 15.4.1 – and suddenly received a pop-up saying there was an issue with my iMessages setup – something to the effect that I needed to sign in again. This after an unusual spike in my data usage this morning (as in, in excess of a GB).
Now, switching iMessage and FaceTime on and off, leaves a "Activation unsuccessful. Turn on iMessage to try again" message underneath the toggle, inside Settings/Messages. And a flurry of popups on my Mac, saying I've signed in on an iPhone, "new" Apple Watch etc. – and that I can ignore if this was me signing in...
Anyone else seeing issues?
I'm experiencing something very similar.
In my case I've had this issue since I got my new iPhone at the end of March. This is my first iPhone and my number has never been registered with iMessage/Facetime before. Also running iOS 15.4.1. The issue was also present on 15.4.
I've also experienced the excessive data usage - very weird. When I first set up my iPhone I got the usual message warning your carrier may charge for the activation messages. I tapped 'OK' and almost immediately I started getting messages from Vodacom that my data bundle is being depleted. Even though I was on WiFi at the time.
I'm getting the exact same "activation unsuccessful" message. I've contacted Apple support multiple times now and together with them we tried pretty much every single thing they could think of. Everyone I have spoken to at the senior support desk is stumped by this issue. My support advisor even got my case escalated so that the engineers could take a look. They came back and said there were some issues on my account that they cleared and that my stuff should be sorted within 48 hours. Still not working.
Apple now insists that I need to get a case opened with my carrier so I can provide them with a case/reference number to take the issue further.
I should also mention that when this issue started I was on Vodacom. After about two weeks of struggling I decided to port my number to Cell C hoping that might fix the problem. I've been meaning to port to them anyway since they changed over to MTN infrastructure in my area and the network is great now. That hasn't solved the problem either. I am at my wits end with this.
I saw on another Mybb thread from last year someone was able to get things working by doing a SIM swap and then loading airtime bought from a store. Person was very specific about having to buy the airtime from a store and not online or via banking app. Don't know why that would make a difference.
Before I begin the struggle that is trying to escalate with Cell C support I am going to try doing a SIM swap and then loading airtime bought from a store. I will post an update later.
I would also like to mention that it looks like I am being charged for each failed activation attempt. Apple support told me that if I am on a supported carrier I shouldn't be charged. Maybe just another sign that something has gone wrong in the back end...
Glad to hear I'm not the only one. If anyone manages to sort this out please let us know!
