- <p>The name <strong>SaveMySugar</strong> was born as a take on the price of
the old conventional Texting service which is quite high, see <a href="http://web.archive.org/web/20121030162247/http://gthing.net/the-true-price-of-sms-messages/" title="Wayback Machine: The True Price of SMS Messages">The True Price of SMS Messages</a>, and it is also a reference to the distress signal <em>Save Our Soul</em> (SOS) used in Morse communications.</p>

<p>On the receiving side the symmetric operations are performed when phone rings are detected.</p>
- <p>This is basically a <em>Pulse-Distance Modulation</em> (PDM), this scheme has been chosen because it's easy to detect when a phone starts ringing, but it's not always easy to detect for how log it rings, or how many rings there are in a single call.</p>
