Apple deletes the SIM card phone number from the iMessage configuration when you swap or remove that SIM card.
This is a well-founded concern! Apple limits phone numbers on an Apple ID based on the SIM card installed in the iPhone or iPad. If you have WiFi but no cell service, you can still get messages via iMessage but not SMS messages.Ĭustomers worry that iMessage stops working when they port, or transfer, their phone number to Tossable Digits. SMS must use a mobile network connection, limiting availability. iMessage uses your data connection, so it is available in more places.
It is exclusively available on Apple iPhones, iPads, and Mac products. It is an end-to-end encrypted messaging service. Apple iMessage is one of the safest ways to communicate.
