Meaning of ‘Your SIM sent a text message’

A silent text message is sent by some mobile carriers in Australia to confirm the SIM card functionality. This often occurs after a system update, roaming session, or change in mobile plan.
3. iMessage or activation of FaceTime
When activating iMessage or FaceTime, iPhones send a hidden message to Apple servers for verification. This might activate the ‘Your SIM sent a text message’ notification, particularly when changing devices or inserting a new SIM.
