Unable to send iMessage in IOS 17 and IOS 18, receive ok
At some point in IOS 17.6 I was no longer able to send iMessages on my iPhone 13 Pro Max. The iMessage send will always fail. Sometimes it will automatically switch to SMS, sometimes I have to manually send SMS (click ! to sent to SMS). The return messages from the other end would come back as iMessage. I know what based on the “Text Message - SMS” and the “iMessage” labels above the message.I have AT&T Wireless if that matters and home WiFi
The interesting part is I can send iMessages without issue on my iPad and iMac. I do have both linked to my iPhone.
I did the following things (in not necessarily this order) all with the same behavior
- I updated to IOS 17.7
- I turned off and turned iMessage on multiple times
- I restarted multiple times
- I turned off cellular and cellular data multiple times on IOS 17 through Control Panel and Settings
- I did a complete reset and restored from backup
- I did a “NFU restore” to IOS 18 (thought it may be hacked) without restoring from backup
- I turned off cellular and cellular data multiple times on IOS 18 through Control Panel and Settings. For some reason it still sent a SMS message
- I am sure there are a few other things I tried
In summary,
- I cannot send iMessages from my iPhone 13 Pro Max using IOS 17 and IOS 18
- I can receive iMessages on both IOS 17 and IOS 18
Any idea what might be going on?
