ETravelSim does not provide an unlimited data eSIM for East Asia. Travelers who need a larger data allowance can choose from fixedโdata plans. For example, the Global Explorer Pass offers 20GB for 30 days at $27.00 USD covering Japan, South Korea, Hong Kong, Macau and 13 additional countries. Similarly, the Seafarer eSIM provides 20GB for 30 days at $29.99 USD and covers China, Hong Kong, Japan, South Korea, Macau, Taiwan and more than 120 other countries. While these plans may be more economical for many users, the choice of data size and validity remains limited to the fixed options available from ETravelSim.
