The company was founded in 1878 as the Eastern Extension Australasia and China Telegraph Company which is a subsidiary of Britain’s Cable and Wireless when it was authorized by the Spanish government to provide its first telegraph services. 

In 1974, President Ferdinand Marcos signed Presidential Decree No. 489, authorized the transfer of Eastern Extension’s franchise to a newly established firm Eastern Telecommunications Philippines (ETPI). The firm was co-owned by Universal Molasses Corporation (UNIMOLCO), and a consortium led by three businessmen (collectively known themselves as the “BAN Group”) who were cronies of the Marcoses: Jose L. Africa, Manuel H. Nieto Jr., and Roberto Benedicto.

After being decommissioned during the period following the end of martial law and many changes, in 2005, ETPI was privatized after Roberto Ongpin bought back 67.5% of the company and 1 year later, the government officially sold the remaining shares to Roberto.

In 2016, ETPI was sold to joint owners PLDT and Globe Telecom. In August 2019, Eastern provided a digital kiosk named MNLKonek (initially known as Iskonek) in partnership with the City Government of Manila which offers free Wi-Fi connection, calls, and phone charging. It was launched first at the Bonifacio Shrine and has since been expanded to 34 units along España Boulevard by the following year.

In February 2021, Eastern announced a nationwide upgrade program with the company spending a budget of ₱2.8 billion to expand its services in Davao City, Cagayan de Oro, Dumaguete, Tagbilaran, Bacolod, Roxas, Kalibo, Caticlan, Boracay, Naga, Legazpi, Iriga and Sorsogon province. 

At present, Eastern Communications offers fixed broadband services in Metro Manila (Makati, Ortigas Center, Manila, Caloocan and Navotas), Cavite, Laguna, Baguio, Cebu City, Iloilo and Tuguegarao.
