Switching to a new SIM card often necessitates updating your iMessage settings to reflect your new phone number. If you forget to deregister your old number and associate iMessage with the new SIM number, you will experience issues sending and receiving messages.

    Go to Settings, Tap on Messages, and turn off iMessage
  2. Navigate to SettingsFaceTime → Toggle off FaceTime.

  3. Remove your old SIM card and replace it with the new SIM.
    If you have an eSIM, delete the old eSIM and add the new one.
  4. Restart your iPhone.
  5. Now, go to SettingsPhone → Then, tap My Number.

    Go to Settings, Tap on Phone, and Tap on My Number
  6. If you don’t see your new number, type it into the text field → Tap Save.
