Our Messaging Monitoring pages have been updated to include new configurations, filters, and functionality. Some of these key changes include:

• New Campaign ID, Location ID, and To and From Phone number filters (Usage and Delivery pages)
• Search from Today to 13 months ago (Usage and Delivery pages)
• Explore Delivery % by Carrier, Message Type, and Message Product 
• Monitor peak capacity for MMS and SMS traffic on the updated Capacity (formerly MPS) page

Bandwidth now offers a Business Associate Addendum (BAA) for messaging and voice channels to extend HIPAA obligations to Bandwidth as a service provider, enforcing the HIPAA Security Rule to safeguard Protected Health Information (PHI) that may be exchanged by Covered Entities over our platform.

Please visit our HIPAA-eligible products and services page for an up-to-date list of currently eligible products and services, as we continuously expand the list of products covered by our BAA.

Effective March 7, 2023, Bandwidth will begin selecting “Secondary DCA Sharing Status” for all carriers including AT&T, Verizon, T-Mobile, US Cellular, Interop, and Clearsky in The Campaign Registry (TCR). 

This will allow customers registering through TCR to receive the CAMPAIGN_DCA_COMPLETE webhook which indicates that the campaign has gone through vetting and been accepted by all submitted DCAs.

On January 6, 2023, we will perform a messaging release that may cause changes to the letter case of HTTP headers within HTTP responses and callbacks. For instance, the “Content-Type” header may be changed to “content-type.”

Please validate that your applications are parsing these headers in a case-insensitive fashion in accordance with RFC 9110.

Please review our full list of SMPP SMS Delivery Receipts and Error Codes and Messaging API HTTP Error Codes for more details.

The number of TNs that can be associated with a single 10DLC Campaign is now limited to 49, unless the customer has been approved for a Sub ID. The limit of 49 TNs is consistent with T-Mobile’s policy. Customers will receive an error message when adding 50 or greater TNs.

Beginning February 7, 2022, we’re updating message search API so that users receive 429 error codes when rate limits are exceeded.

Beginning February 15, 2022, we’re removing a few of the previously accepted file types for MMS. We’ll continue to accept all file types on this list.

Keep in mind that downstream carriers may have additional limitations that can affect deliverability. Jpeg, png, and gif images continue to be the most widely supported amongst carriers.

Customers needing to apply for a sub-id to support registering greater than 49 TNs per campaign are now able to do so. Click here for more information. 

Registration of Sole Proprietor campaigns and brands is now available via the Bandwidth App Portal and API.
