<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.
