The constraints on the number of recipients in a multimedia message service (MMS) or short message service (SMS) communication sent via the Android operating system exist to optimize network performance and manage resource allocation. These restrictions, often implemented by mobile carriers and device manufacturers, prevent system overload and ensure a consistent user experience for all subscribers. For example, a user might be limited to sending a message to a maximum of ten recipients simultaneously.
The imposition of such limitations serves several crucial functions. It reduces the risk of spamming and unsolicited messaging, mitigates network congestion by limiting the bandwidth consumed by large-scale broadcasts, and controls costs associated with message delivery, which can be significant for carriers. Historically, these limits were lower due to technological constraints. As infrastructure has evolved, some carriers have increased these allowances, but the fundamental need for them remains.
