Happy to help! So that we may best assist, can you provide context for this question? If you are referring to your cellular module ID number, you can submit any module ID change requests for new or existing service via our secure message tool here.

If this is for a new service order and you received an email from our team stating your module number is invalid, you can also just provide the number in reply to the notification email.
