The limitation of SMS length, initially dictated by technical constraints, affects message segmentation within the Android operating system. Specifically, when a text exceeds the standard 160 characters, it is often broken down into smaller segments. The number 128 refers to the maximum count of such segments permitted for a single outbound transmission on certain Android platforms. For instance, a lengthy message might be split into multiple parts to adhere to carrier specifications.
This segment limit influences the user experience by potentially impacting the order of message delivery or creating confusion when a long text is received piecemeal. Understanding this constraint is crucial for developers creating SMS-based applications and for users who regularly send extensive texts. Historically, limitations in SMS infrastructure were a major factor, but modern implementations are evolving, with some carriers and devices offering enhanced SMS or transitioning to richer messaging services.
