Hello, I am unable to all of a sudden send text messages to any device other than iPhone users. When a friend texted me on her iphone, she said it was sent as an sms instead of an iMessage.
I have done the following suggested fixes but none have been succesfull:
1. disabled/enabled imessages
2. restarted device
3. restore network settings
4. made sure that the SMS option is turned on.
I have an Iphone 5 and updated it to the new iOS 9 when it was released, but this issue only started happening a few days ago.
Please help, nothing online seems to be helping my issue. My last resort is to obviously call tech support, but I am stubborn and I would like to troubleshoot on my own, so I'll know what to do next time this happens.
