I just upgraded to iOS 10.2, and now when I send a message to my niece (who has her WiFi and Mobile Data off, but Voice+Text Cellular on) it always goes as iMessage instead of auto-sending as an SMS as it used to. She then does not get it until she turns on her data.
This only happens with my niece who has an old iPhone 4. She is unable to upgrade to iOS 10, so maybe that has something to do with this issue? It was fine prior to me upgrading to iOS 10.2 (messages to her when she had data connection were sent as SMS so she used to actually get them when offline). When one of my friends—who has iOS 10.2—has no internet connection, messages to him are sent as SMS automatically so he actually gets them. How can I get messages to my daughter to send as SMS automatically when she's disconnected from the internet but not from calls and texts?
I have enabled
Send as SMS when iMessage is unavailable.
tl;dr by owlswipe: Messages to my niece's iPhone when she's disconnected to the internet but connected to voice + text used to automatically send as SMS instead of iMessage, but they no longer do. How can I restore the old behavior?
