WhatSim

WhatSim is a stroke of genius. And it has come a long way.

WhatSim is the stroke of genius of Manuel Zanella, founder and CEO of Zeromobile. In 2003, after his honeymoon in Kenya where he spent a fortune in phone calls, Manuel Zanella had the idea of creating a SIM card to reduce the cost of international roaming. In 2007 he created Zeromobile, the mobile company for low cost roaming that allows you to save up to 85% on the cost of incoming and outgoing calls, text messages and mobile Internet. And you can receive free in over 140 countries. Now with this new idea, WhatSim, he has created a revolutionary SIM card to chat for free with WhatsApp, the world's most popular messaging system.
