This is a Module for MAXS, which does not install any launcher. You need "MAXS Main" and a configured MAXS Transport to make use of it. The SmsWrite module can be used to modify the system's SMS database, e.g. add new messages to it. The main purpose is to add messages send by module-smssend, to the outbox. It can optionally make use of the ContactsRead module, if installed.
