This Dutch TV report hosted by Ruud Elmendor covers two Kenyan men in wheelchairs (they lost the use of their legs due to polio) who have started a mobile pay-phone business, using phones attached to their chairs. They started the business as an alternative to begging, which is difficult due to police rousts; however, operating an unlicensed wheelchair phone is also subject to police hassles.
