With the proliferation of mobile and internet penetration in target communities, it is now possible to reach more people than ever, however, identifying the most effective communication strategy is often difficult. Mobile data costs can be prohibitively expensive and network coverage is often unpredictable, additionally, there is an enormous range of devices in use ranging from smart phones to more basic text based mobiles. Every1Mobile has built a platform to specifically address these challenges and it is helping to make a real difference to people’s lives.
