Wikipedia Zero is an initiative to enable mobile access to Wikipedia free of data charges in developing countries. The objective of the program is to reduce barriers to accessing free knowledge—one of the largest barriers being cost of data usage.
Detailed information about this program, including where it is available, can be found at the Wikipedia Zero page, the Wikimedia Q&A page and in the Wikipedia Zero category of the Wikimedia blog.
If you are an operator wishing to provide subscribers free access to Wikipedia, please email wikipediazerowikimedia.org to get started with Wikipedia Zero!
