SMS shows “Not Delivered”

My mom recently got a new iPhone XR, but when she tries to send any SMS messages to people without an iPhone, it shows “Not Delivered”. She can still call and receive SMS messages. In the iMessage settings pane, the “Send as SMS” setting is enabled. This is happening with multiple people too.

SMS/MMS are carrier services, make sure your carrier has SMS/MMS provision properly.

Talk to them.
