The NCC of Taiwan, China has issued an official notice requiring mobile phones sold and used in the Taiwan region of China to automatically disable the function of connecting to 2G (GSM) base stations, in order to prevent criminals from committing fraud through fake base stations.
The implementation measures are as follows:
Mobile phones that obtained type approval between 1 September 2021 and 31 August 2023 must have the 2G connection function disabled through an OTA update before 31 March 2024, or earlier;
Mobile phones that obtain type approval after 1 September 2023 must have the connection to 2G (GSM) base stations disabled by default, and 2G must not be enabled within the Taiwan region of China when the product is placed on the market;
Consumers are permitted to enable 2G connectivity outside the Taiwan region of China.
If mobile phone manufacturers have any comments on the above, they may send them to the NCC by letter before 5 May 2023.
