KalSMS is a SMS/MMS gateway running entirely as an Android app.
|
|
|
|
<p>
|
|
It enables web services to send and receive SMS/MMS messages
|
|
by forwarding incoming messages to a server on the Internet, and sending
|
|
outgoing messages to other phones.
|
|
</p>
|
|
|
|
<p>
|
|
People with any type of mobile phone can send SMS/MMS to a phone
|
|
running KalSMS, without needing their own Android phone.
|
|
</p>
|
|
|
|
<p>
|
|
It works wherever the phone can receive SMS messages and access the Internet
|
|
(via Wi-Fi or mobile data connection).
|
|
</p>
|
|
|
|
<h2>Why KalSMS?</h2>
|
|
|
|
<p>
|
|
KalSMS can be used nearly anywhere in the world. In particular, it is useful
|
|
in countries where obtaining a local virtual phone number
|
|
or SMS shortcode is difficult, expensive, or impossible. A phone running KalSMS
|
|
connects to the phone network in the same way as any other mobile phone,
|
|
so it can be set up without needing approval from anyone else.
|
|
</p>
|
|
|
|
<p>
|
|
KalSMS is designed to to be maintainable even when deployed in remote locations
|
|
that cannot easily be accessed by your organization's technical staff. KalSMS is simple
|
|
enough for non-technical users to do all setup and maintenance of deployed phones.
|
|
</p>
|
|
|
|
|
|
<h2>Price</h2>
|
|
<p>
|
|
The KalSMS app itself is free to install on as many phones as you'd like.
|
|
</p>
|
|
<p>
|
|
In order to deploy KalSMS, the only monetary costs are the cost of a messaging
|
|
plan for your phone, and the price of the phone itself. KalSMS is compatible with
|
|
many old or inexpensive Android phones, e.g. the LG GT540, currently $120 on Amazon.com.
|
|
</p>
|
|
|
|
<p>
|
|
Typically your organization will need only one phone running KalSMS in a
|
|
particular country, although you could have multiple phones to load-balance requests
|
|
for higher throughput, to offer different user services, or to serve different mobile networks.
|
|
</p>
|
|
|
|
<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. KalSMS likelly 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.
