<h2>Comparison to Alternative Methods</h2>
<p>
SMS gateways can be created using several alternative methods, including hosted services (e.g. Twilio, Tropo, Clickatell),
connecting GSM phones/modems to a computer (e.g. FrontlineSMS, RapidSMS, Kannel),
and partnering directly with mobile operators.

<p>
KalSMS is ideal for situations where no hosted services with local numbers are available in
a particular country, or when it is necessary to receive MMS messages.
</p>
<p>
KalSMS likely has lower throughput than hosted services or partnering with mobile operators, but should
be able to forward up to a few thousand messages per phone per day.
