- De-register is only done if you want to use the same number in an Android phones. If you are discarding the number then you need not de-register.
- If you want to change the SIM with same number, you do not require to do anything.
- If you want to change to SIM with new number, you need to disable iMessage and FaceTime on your iPhone and then remove the old number from Apple ID. This is not de-registering. Watch the GIF below, how to remove the old number from Apple ID.
