While many major Asian cities are rapidly expanding their 5G networks, 5G availability with EastESIM varies by country and specific location. In tech-forward hubs like South Korea, Singapore, and parts of China, 5G is quite prevalent in urban areas. However, in other regions or more rural parts of Asia, the primary and most robust network will still be 4G LTE, which offers excellent speeds for most travelers' needs. EastESIM always connects you to the best available network, ensuring reliable connectivity wherever you are in Asia.
