2. Click the [Domain > Change Information > Change Owner Information (or Change Administrator Information) menu.
3. Select the domain whose information you want to change > Click the Change Owner Information button (you can also select multiple domains).
4. Click the Verify button in the mobile phone number section > Click the Send Verification Key button in the new window.
5. Enter the authentication key received via SMS at the bottom and click Authenticate to enter a new mobile phone number.
6. Enter the new number and click the change button to complete.
