Overview:
MMS group chat messaging refers to the capability of sending text messages, multimedia content (such as pictures, videos, audio clips), and other data to multiple recipients simultaneously within a single message thread.
Unlike SMS, which typically only supports plain text messages limited to 160 characters, MMS allows for the transmission of richer multimedia content and longer messages. Group chat messaging extends this capability to multiple recipients, enabling users to create group conversations where everyone can participate and view the messages sent by others in the group.
Group chat messaging is commonly supported by modern smartphones and messaging apps, allowing users to engage in group conversations with friends, family, or colleagues, and share various types of multimedia content in a single thread.
Availability and Reach:
Group chat messaging is available on the 10DLC product for US Wireless carriers: AT&T, T-Mobile US, Verizon Wireless, U.S. Cellular, and Google Voice.
- Currently supported on the Sinch MM7 API.
- Up to 20 message recipients supported.
Please review our MM7 API developer documentation for detailed instructions on sending and receiving group chat messages, as well as information on the error codes introduced for group chat.
Compliance Concerns:
Honoring User Opt-Out
In accordance with Messaging Principles and Best Practices, content providers must establish systems that allow consumers to opt out of A2P messaging. Users should be able to unsubscribe using keywords such as STOP, END, UNSUBSCRIBE, CANCEL, QUIT, or phrases like "Please remove me" or "Stop sending messages." Once opted out, users must be quickly removed from the messaging list, and the content provider should cease all communications, sending only a final confirmation message of the opt-out.
Person-to-Person Messaging
In group chat messaging, if a user wishes to be removed from a group chat, they may still receive unwanted messages from other participants who continue to respond to the old thread. This means that even after a user has opted out of receiving messages from the content provider, they might still receive replies from other group members. Since P2P messaging involves a direct route through carrier networks with minimal intermediate handling, the ability to impose additional restrictions specific to A2P communications, like blocking or content filters, does not exist in the P2P model.
Use-Case:
Group chat messaging, while an essential communication tool, presents unique challenges, particularly in larger groups. The high volume of messages can overwhelm users, causing important information to get lost in the clutter. Moreover, not every messaging need is well-suited for group chat messaging. However, there are several use-cases where group messaging excels:
Project Collaboration
Enables team members to discuss projects and stay updated in real time, fostering a collaborative environment that enhances productivity and speeds up decision-making.
Real Estate Updates
Realtors can efficiently keep potential buyers up-to-date with the latest listings, open house schedules, and other relevant news, streamlining the communication process in a dynamic market.
Home Security
Security companies can instantly notify homeowners of security alerts, whether at their residence or place of business, ensuring rapid dissemination of critical information for immediate action.
Automotive Insurance
In the event of an accident, insurance companies can use group messaging to coordinate communication between the driver of the vehicle, insurance agent, tow service, and interested family members, simplifying the management of the incident and support processes.
