These Service Specific Terms for the Business Number ID (or BNID) Service (“BNID Terms”) govern Customer’s use of the Services described below and are in addition to and incorporate by reference the First Orion Terms of Service located at https://firstorion.com/first-orion-customer-portal-terms-of-service/ (the “Terms”). Capitalized terms used but not defined in these Service Specific Terms will have the respective meanings assigned to them in the Terms. If you do not agree to these Service Specific Terms or any changes thereto, your sole remedy is to stop using the Services. Use of the Services after any changes shall constitute acceptance of the updated BNID Terms.

1. Definitions. The following capitalized terms shall have the meanings set forth below.

“Business Number ID Service” or “BNID Service” means a service that results in the substitution in signaling of a Preferred Display Number for the Calling Number from which the call originates.

“Calling Number” means a T-Mobile MSISDN for which Customer substitutes a Preferred Display Number using the BNID Service. A Calling Number may be mapped to only one Preferred Display Number.

“Preferred Display Number” means the business phone number Customer designates for display when utilizing the BNID Service. Customer may have multiple Preferred Display Numbers with multiple Calling Numbers mapped to each.

“TfB Subscriber” means a business enterprise that has contracted with T-Mobile to obtain T-Mobile MSISDNs for its business calling needs. For the purposes of the BNID Service, a TfB Subscriber refers exclusively to a business entity (other than a sole proprietor) and not an individual consumer or entity otherwise excluded by T-Mobile, that uses Calling Numbers in connection with its business operations.

2. Use of the BNID Service
1. In order to use the BNID Service, Customer must be a TfB Subscriber and must have completed and passed the Registration process as described in the Service Specific Terms for Business Registration and Business Certification, including verification of the Customer’s right of use of the Calling Numbers and Preferred Display Number.
2. The BNID Service allows businesses to substitute a Preferred Display Number for the Calling Number from which the call originates; user instructions will be made available on the Customer Portal. Standard reports available to Customer include the total number of Calling Numbers mapped to a Preferred Display Number during the month.
3. First Orion may impose additional restrictions and/or prohibitions on the use of the BNID Service to the extent they are imposed by T-Mobile or applicable law. First Orion will notify Customer of any such restrictions and/or prohibitions as soon as reasonably possible after receiving notice thereof.
4. Customer agrees to comply with the Acceptable Use Policy, which can be found at https://firstorion.com/acceptable-use-policy/, in connection with its use of the BNID Service.
