Editing SMS (section)

=== Threaded SMS ===
Threaded SMS is a visual styling orientation of SMS message history that arranges messages to and from a contact in chronological order on a single screen. It was first invented by a developer working to implement the SMS client for the BlackBerry, who was looking to make use of the blank screen left below the message on a device with a larger screen capable of displaying far more than the usual 160 characters, and was inspired by threaded Reply conversations in email.<ref>{{US patent|7028263}}</ref>

Visually, this style of representation provides a back-and-forth chat-like history for each individual contact.<ref>{{cite web |url=https://www.phonescoop.com/glossary/term.php?gid=455 |title=Threaded Messaging |website=Phone Scoop |access-date=29 September 2024}}</ref>  Hierarchical-threading at the [[Conversation threading#Advantages|conversation-level]] (as typical in blogs and online messaging boards) is not widely supported by SMS messaging clients.  This limitation is due to the fact that there is no [[session identifier]] or subject-line passed back and forth between sent and received messages in the [[Header (computing)|header]] data (as specified by SMS protocol) from which the client device can properly thread an incoming message to a specific dialogue, or even to a specific message within a dialogue.
