Why is iMessage still working
I have an iPhone 13 with no SIM card but connected to WiFi.. iMessage and FaceTime are toggled off. I don’t send or receive text messages on this phone.
I also have an iPhone SE (2020) with a SIM card and WiFi with iMessage and FaceTime turned on. This is my main phone and is used for all communications. iMessage Send & Receive is by phone number only.
After restarting my iPhone 13 all of my text messages from the iPhone SE will show up on the iPhone 13 (stock messages app).
How is iMessage still working despite it being turned off for the iPhone 13?
iPhone SE, iOS 15
