The group of business magnate Michael Cosiquien-led ISOC Infrastructure Inc. and Malaysia's edotco Sdn Bhd is in talks with third telco player Dito Telecomunity Inc. for a possible partnership. Cosiquien said negotiations involve building cell towers for Dito, a joint venture between Dennis Uy and China Telecom. ISOC and edotco have formed a 50-50 joint venture corporation that will carry out their goal to upgrade the country's telco infrastructure. The new entity called ISOC edotco Towers Inc., will have an initial capital of $10 million. Cosiquien said the new corporation plans to build 400 to 500 cell sites in its first year of operations. Suresh Sidhu, CEO of edotco, said the joint venture company would invest up to $100 million in the next few years to build at least 1,000 cell towers across the country.
