Support for receiving SMS messages longer than 1600 characters.

Currently, messages exceeding 1600 characters are not delivered, and users are unable to receive them even in parts. This is causing important communication to be lost, especially for users whose clients may send long messages (e.g., detailed updates, instructions, or responses). It would be highly beneficial to have a mechanism that either supports concatenated messages beyond 1600 characters or splits and delivers them in segments. This enhancement would improve user experience and reliability of communication. Please notify the user once this feature is supported.
