As an undersea optical cable route directly connecting Southeast Asia with the US, AAG has been officially put into operation since November 2009. The countries and territories that the AAG undersea cable route passes through include Malaysia, Singapore, Thailand, Vietnam (the cable branch turns into Vietnam with a length of 314km, the landing point in Vung Tau), Brunei, Hong Kong (China) States), the Philippines and the United States (Guam, Hawaii and California).

In more than 12 years of being put into operation, despite frequent problems, according to experts, for many reasons, AAG traffic is still used by many domestic carriers at a large rate. This is also the reason why when there is a problem, the AAG cable greatly affects the quality of international services provided to users of the network, especially in the early days.

In addition to AAG, at the moment there is another undersea cable route that also has problems, namely Asia Pacific Gateway (APG). The cable route has been interrupted since December 13, 2021 due to a cable fault about 125 km from the Hong Kong (China) docking station of the APG route. According to the plan, it is expected that the problem on the APG cable line will be fixed from February 2, 2022 to February 6, 2022.

The APG cable was officially put into operation in mid-December 2016, with a length of about 10,400 km, located underground in the Pacific Ocean, with the ability to provide a maximum bandwidth of up to 54 Tbps. With the participation of the network operators VNPT, Viettel, FPT Telecom, CMC Telecom of Vietnam, APG is considered as a cable route contributing to bringing a stable transmission line with a larger capacity for Internet users in Vietnam. .
