How to update your iMessage phone number?
Step 1: Ensure iMessage is turned on
- Before making any changes, go to Settings > Messages and make sure iMessage is enabled. Wait a moment if prompted. That gives iMessage time to activate.
Step 2: Adjust “Send & Receive” settings
- Open Settings > Messages > Send & Receive. In this section, check that your new phone number is selected under “You can receive iMessages to and reply from.” If not, do that.
Step 3: Change your “Start New Conversations From” number
- Still in Send & Receive, find the Start New Conversations From option. Choose your new number if it is available.
Step 4: Turn off iMessage and FaceTime
- Toggle off both iMessage and FaceTime from settings. This resets their connection with your number.
Step 5: Swap your SIM or update your number
- Remove the old SIM and insert the new one. If you use eSIM, delete the previous profile and add the new one. Go to Settings > Phone > My Number to make sure it shows your new number. If it does not, tap and enter it manually. Then save it.
Step 6: Restart your device
- Turn your iPhone off, wait a few seconds, then turn it back on. This final step helps iMessage and FaceTime pick up the new number.
Step 7: Turn iMessage and FaceTime back on
- Head back to Settings > Messages and enable iMessage, then go to Settings > FaceTime and enable FaceTime.
- Go again to Send & Receive and pick your new number.
- When the verification pop-up appears, tap Turn On and wait for confirmation.
Reset Network Settings (if needed)
- If your new number is still missing or greyed out, go to Settings > General > Reset > Reset Network Settings and confirm. Then repeat the earlier steps.
Tips
- Always wait for activation to finish. Do not rush tapping through.
- Make sure your date and time settings are set to automatic. That helps iMessage verify quickly.
- If a wrong number persists, sign out of your Apple ID in Messages or FaceTime, then sign back in.
- After changing your number, check all Apple devices and confirm they use the same Apple ID with the updated number in “Send & Receive.”
