SMSgate

SMSgate is an Android app that sends SMS-messages from JSON data fetched from a URL. It also forwards received SMS-messages to the same URL, as POST requests. It is intended to use as a way to send and receive SMS-messages from webpages.

Note that the app prevents the phone from sleeping, and therefore should only be used, when connected to a charger. Also be aware that Android usually contains a limit for how many messages can be send - you will need root to circumvent this limitation.

The sourcecode for the app can be found on Github: https://github.com/chpoul/smsgate
The Github README also includes, how JSON containing messages should be formed, and what POST requests are send from the app.
