PLDT and DITO Telecommunity have signed a memorandum of understanding (MoU) to share network infrastructure in the Philippines.The MoU aims to expand nationwide network coverage across the country at a more economical cost for the two carriers.As part of the agreement, the two telcos will share telecoms infrastructure, without paying fees to one another. This will see PLDT and DITO grant each telco reciprocal rights to use eligible tower sites.The MoU also covers in-building solution (IBS) colocation, which the companies said will enable them to share telecommunications infrastructure within commercial buildings and other indoor locations, and submarine cable capacity through indefeasible right of use (IRU) arrangements.This will see both carriers save money on deploying network infrastructure, while the duplication of equipment is also reduced."Connecting the country is a responsibility that we all share as Philippine telcos. This agreement reflects that, even as we compete in the marketplace, we can collaborate where it matters the most: accelerating digital inclusion, helping connect every Filipino, and creating greater opportunities for our people and our nation,” said Manuel V. Pangilinan, chairman and CEO, PLDT.Eric Alberto, president and CEO, DITO Telecommunity, added: "This partnership that we are forging today is a modest one. This allows both companies to deliver much better services for all our respective customers."PLDT, which provides mobile services via its subsidiary Smart Communications, and DITO are two of the three big telecom providers in the Philippines, along with Globe Telecom.PLDT has around 66 million mobile customers, while DITO, which was set up to challenge the PLDT and Globe duopoly, serves around 17 million subscribers.
