merdata eSIM Data Plans for East Asia

Merdata does not provide a truly unlimited data eSIM for East Asia. The provider’s plans in this region are fixed data plans, each offering a set amount of data that must be used within a specified validity period. For example, the eSIM Asia (20 GB 30 days) plan gives 20 GB of data for 30 days and costs $84.90 USD, while the eSIM Asia & Oceania (20 GB 90 days) plan also offers 20 GB of data but for 90 days at $84.90 USD. Because the data allowance is capped, these options may be more cost‑effective for most travelers compared to an unlimited plan, unless one is a very heavy data user.

merdata's East Asia eSIM offerings do not include a phone number or SMS capability; the available plans are data‑only. Travelers can use the data connection for VoIP applications such as WhatsApp, Telegram, and iMessage to make calls and send messages. However, some destinations in East Asia may block or restrict access to certain apps or VoIP services, so it is advisable to confirm the availability of any required applications before purchasing.

Merdata offers several eSIM plans in East Asia that cover the following countries: China, Hong Kong, Japan, South Korea, Macau, and Taiwan. The “eSIM Asia (20 countries)/day” plan includes China, Hong Kong, Japan, South Korea, and Taiwan; the “eSIM Asia (12 countries)/day” plan adds Macau to that list; the “eSIM Asia & Oceania (20 countries)” plan covers China, Hong Kong, Japan, South Korea, and Macau; the “eSIM Global (117 countries)” plan and the “eSIM Global (127 countries)” plan both cover China, Hong Kong, Japan, South Korea, and Taiwan; and the “eSIM Asia (13 countries)” plan likewise covers China, Hong Kong, Japan, South Korea, Macau, and Taiwan. All of these plans extend beyond East Asia to other regions, but the above countries are the ones included within the East Asian coverage for each plan.
