You guys are missing something in the timing. Sending an SMS message
requires far more than just keying in the receiver's phone number and
the text itself. Once all this is keyed in and the send button is
pressed, the cell system takes over. Much like the email system we are
now using, the SMS message is forwarded into the SMS gateway, which
is most likely located at some central point in the cellphone
company's system. There are amazingly few of these due to the vast
amount of bandwidth inside the phone companies. The next time the
system services outgoing messages, the server will start checking for
delivery parameters, such as if the receiving phone is available and
ready to accept a message. When all these gates have been cleared, the
message is forwarded to the receiver. Only then does the message come
up for display. This can happen quickly (hundreds of milliseconds), or
rather slowly (minutes or more) depending on the loading of the SMS
system and the overall cell system.
Jack, what you say is true. However, you're missing the fact that the
kid was still in the process of keying in his sentence when the code
guys had finished. It would be interesting to know just how far he had
gotten, but it is clear it was not to the end.
