New news has come up from WhatsApp, one of the most popular instant messaging services worldwide, as they announced that it has 700 million active users. The news is that, an Italian company has launched WhatSim, an only SIM that comes with a plan that will let you use the popular messaging app for free while travelling across about 150 countries. WhatSim is an extraordinary opportunity for WhatsApp. WhatSim is available to buy via the WhatSim website, with the company also planning to make it available via "network of local distributors in over 100 countries. Recharge is also done quickly and and easily by just going to the website even from smartphone and soon even from a dedicated app." According to Manuel Zanella Rngineer, Founder and CEO of Zeromobile Its only "limit" is the data connection especially when you are traveling because the roaming charges are expensive and you can't always find Wi-Fi everywhere and it is not always free.
