If you have changed your phone number, you can update your iPlum Login ID to match with it.
You can also use this option is you are an admin and want to change the Login ID for another user in the account.
Login to secure online portal https://my.iplum.com.
Select “Accounts” in the left menu bar. Click Actions >> Profile and click the edit icon next to iPlum ID (same as Login-ID), Caller ID Name or Email. If you don’t see the options, just refresh the page. When you are changing the iPlum ID, the system will send you a verification code on the new phone number which you are setting as iPlum ID.
