During deliberations on Senate Bill 1636, which requires public telecom entities to provide nationwide mobile number portability to subscribers, Sen. Lacson sought to remove interconnection fees or charges for calls or SMS made from one network to another. “We are here to protect the consumers. And the consumer, not being made aware he is calling through a different PTE (public telecommunications entity), is helpless in being charged with P2.50 for mobile calls and 15 centavos for SMS.”
