Confusing situation with iMessage vs. SMS
Hello,
My girlfriend has an iPhone and iPad. I setup so that she receives iMessages on both devices using her phone number. The issue is that she doesn't have data on her iPhone, and sometimes she leaves the iPad at home where there is wifi.
So I send her an iMessage, and it says "delivered", but that's because it was sent to her iPad. Her iPhone never got it since she has no data. So in order for me to actually send her a text message to her iPhone is:
1) Disable cellular on my phone.
2) Disable wifi on my phone.
3) Send her a text message (as SMS).
This way, I avoid it going through iMessage, and I know her iPhone (which has no data, can get my message).
Now how can I solve for this? I'd like to keep my data/wifi on and not have to go through the steps above. Ideally I'd like her iPhone to get my SMS (she her iPhone has no data), and her iPad to get my iMessage.
iPhone 6s, iOS 11.2.5
