Grameen Telephone
Abdul Quadri worked as an investment banker in the US and was inspired by the ideas of the Grameen Bank. He returned to his native Bangladesh with the idea of making a low cost mobile phone service available in rural areas. He also began the Village Phone program which is now available in over 50,000 villages, as well as Community Information Centers to provide Internet access.
