Thanks to you both. This helps a great deal and I can avoid hunting for a field that doesn't exist.

(I.e. How do we follow a conversation thread?) That's not directly achievable with SMS in general. There's no "message-id" on the SMS protocol at all, so there's no way to tell if a message is a response to another. Usually this is achieved with some sort of sessions implementation by using a time window: If you send a message to a given number and that number sends a message back before a predefined time window, that message is considered an "answer".
