The Undersecretariat of Telecommunications, the Subsecretaria de Telecomunicaciones (SUBTEL), a subcabinet level arm of the Ministry of Transportation and Telecommunications (MTT), acts as both telecommunications policymaker and regulator in Chile.
Under SUBTEL regulations, all ISPs must interconnect domestically and provide consistent consumer information on service features such as latency rates and packet size for quality of service purposes.
In July 2010, the Chilean Congress approved a Net-Neutrality Law that guarantees that ISPs cannot interfere with content accessed by Internet users. SUBTEL’s implementing regulations were published on March 18, 2011. In addition to ensuring users have access to content without discrimination, the regulations permit ISPs to offer tiered speed service levels and tiered pricing.
