Concatenated SMS messages are messages that comprise more than 160 characters for Latin alphabets or 70 characters for other alphabets. These longer messages are created by splitting the text into smaller segments, each fitting within the character limit, and sending them sequentially. When the recipient receives these segmented messages, their device reassembles them to display the complete message as originally composed.


It's important to note that while concatenated SMS messages allow you to send longer messages, some mobile devices or networks may have limitations on how they handle such messages. Therefore, it's advisable to test how concatenated messages are received by your intended recipients to ensure the best user experience.
