Hi ​@Laurabrueford, 

Please check if the number under settings is showing correctly:

For iPhone:

- Please change it to the number you wish to keep. It might not allow to change or save immediately.
- If the number does not change kindly open the Settings app. Tap General. Scroll down to the bottom of the list. Tap Reset. The "Reset" option is at the bottom of the Settings menu. ... Tap Reset Network Settings. Enter your passcode if prompted, then tap Reset Network Settings to confirm your choice. This will help.

For android:

This will help determine whether the issue is with the SIM or the handset.
