I have an iPhone 6 with an interesting issue that after doing a bunch of research haven't seen solutions elsewhere. I recently did a full wipe and reinstall of the latest iOS 10 and setup the phone as a new device (did not restore from a backup). Since then I cannot send SMS messages to contacts unless they have previously sent me a message. I also cannot send SMS to things like "text 'blah blah blah" to 123456" type numbers. When I send the SMS, I just get a message send failure.
I also recently tested with my brother. I tried to send a SMS to his number (a Samsung android phone) and could not send. I had him send me a SMS first, which came in properly and linked to his contact with no issue (name showed up on my phone) and I was then able to reply and send SMS to him.
iMessage, internet, phone calls, etc. have not been affected and work fine. Prior to the refresh, everything worked fine with SMS as well, but now is broken.
For solutions, I've tried:
- hard rebooting
- resetting network settings
- disabling LTE
- being on WiFi vs off WiFi
Anything else I can try?
