ncrease MMS Size Limit for Messages to AT&T Numbers or Add Workaround
Summary:
Customers are experiencing MMS delivery failures when sending media files larger than 1 MB to AT&T numbers. The issue stems from AT&T’s strict MMS size limitation.
Request:
Collaborate with AT&T to increase their MMS size limit (currently 1 MB) to match other major U.S. carriers (3–5 MB+).
or
Implement a RingCentral-side workaround, such as:
• Automatic media compression before sending.
• In-app alerts when MMS exceeds carrier limits.
• Option to convert oversized MMS into shareable URLs.
Impact:
Reduces MMS delivery failures and related support volume.
Improves customer experience and reliability of RingCentral messaging services.

High – Affects MMS delivery success for users sending media to AT&T recipients.
