Telecommunications in developing countries lack adequate planning and policies, so their telephone densities show the lowest values worldwide. The failure in considering the complexity of the regional telecommunication system in developing policies and technological strategies has increased the telecom gap between other regions and this particular sector of the world. We used a system dynamics modeling approach as a methodology that deals with the complexity of the system in order to evaluate existing value added services and access technologies in telecommunications that could accelerate the dispersion of regional telephone services in developing countries. The role of wireless systems, which have a low deployment delay, was found to be crucial in the growth of urban and rural telecom infrastructure in developing countries. The value added services were found to have a positive impact by increasing the financial resources of the telecom company and the number of urban telephone lines.
