# Update imported number

Update an imported phone number. You can perform the following updates:

* Update the name that displays for a customer by modifying the displayName parameter.
* Unlink the number from an SMS service or campaign by updating the smsConfiguration configuration object. To unlink a number, submit the request with an empty string (””) in the service plan ID or campaign ID fields.
* Before linking a number to a new service or campaign, it must be unlinked from any existing service or campaign. Then, link the number to a new SMS service or campaign by updating the service plan ID or campaign ID with the new desired value.
