Registration and Logging of Events
All calls, SMS’s and transactions are independently logged and registered by a number of different parties. For instance, when you sent an SMS on the network it is received by your telephony provider, passed on to the destination network (which could be on another network), and delivered to its final destination (the gateway and behind that, the Content provider). All these stations will have logged and registered this event.
Under no circumstance, the CP can simulate sending a message from your phone: some elementary links in the chain would be missing.
