Can I continue to use Voice and SMS service for my Toll-Free Numbers after porting away from Sinch?

[Sabaah_A]

No, once you port away your toll-free number, Sinch no longer has control over the phone number. It will be up to your new carrier to provide voice and/or SMS services. It is also the responsibility of your new carrier to ensure the proper execution of the port. Once Sinch confirms that the port-out has been completed, the phone number will be removed from your account after a short period of time.

However, Sinch may still be able to provide messaging services for some phone numbers, even after they have been ported away. For more details, please refer to Managing your Hosted Numbers.

Unverified toll-free numbers (TFNs) and Pending Verification toll-free numbers (TFNs) are subject to industry-wide message blocking. Unverified toll-free numbers are TFNs that have not completed the toll-free sender verification process. Pending Verification toll-free numbers are TFNs where a verification request has been submitted, but the request is pending review and approval. 

Note: In the past it was possible to send messages from an Unverified TFN or Pending Verification TFN. However, as a result of industry-wide changes, all toll-free numbers, regardless of the use case, must be Verified to originate traffic.

UNVERIFIED toll-free numbers (TFNs) are subject to industry-wide message blocking, effective November 8, 2023.

PENDING VERIFICATION toll-free numbers (TFNs) are subject to industry-wide message blocking, effective January 31, 2024.

All toll-free numbers (TFNs) must be in a VERIFIED state in order to originate traffic.

Unverified TFNs and TFNs pending verification will be blocked with Sinch error code 64 “Blocked due to exceeded quota”. Please see Toll-Free Delivery Report Errors for a full list of Sinch Toll-Free error codes.
