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 Dashboard Portal and API.

Prior to this fix, multi-segment messages to US Cellular were failing due to a limitation in their handling User Data Headers (UDH). This fix means that multiple single-segment messages will have their own DLR.
Customers will receive multiple DLRs unless suppression is implemented.
