Within the project Wikipedia Zero Wikipedia wants to give access to people from developing countries who do not have enough money to pay data charges. In principle the system works as follows: users send a request per SMS to wikipedia and receive the requested article per SMS. Details are currently unknown, according to Kul Takanao Wadhwa (head of mobile strategy Wikimedia) the service shall be introduced in a few months.
Recently Wikpedia received 600.000 US-Dollar from a non-profit organisation in order to expand the current range of Wikipedia. Parts of this funding shall be used to implement the SMS service.
