Notice that Chunghwa Telecom claimed that the 3G network has a history of more than 20 years in Taiwan. After shutting down the relevant 3G base stations , in the future they will focus on building 5G base stations, and existing 4G/5G voice calls will be converted to use VoLTE (Voice over LTE) technology. Far EasTone Telecommunications/Taiwan Mobile claimed that now that the global 5G network has gradually become popular, the 3G network can be said to have "retired after success". After shutting down the 3G base station in the future, the 2100 MHz frequency band used by the 3G network will be used for 4G / 5G communications to improve related services.
