Opening Blocked Sites in UAE

UAE is an important trade and business center in the Middle East and most of its population is made of migrant workers who frequently need to contact their loved ones back home or even keep in touch with their coworkers. Telecom companies made a lot of profit of international phone calls. But then many VoIP applications such as Viber, Tango and Fring appeared. VoIP applications enable users of making free international calls and they're widely used on smarthphones and tablets. So in order to protect their profits, telecom companies contacted Internet service providers in the UAE to ban access to VoIP applications. Also, MagicJack service which enables users to make free phone calls to the USA has been banned there. So what's the best solution for opening blocked sites in UAE?
