RoameSIM eSIM Data Plans for East Asia

RoameSIM does not provide a truly unlimited high‑speed data plan for East Asia. The plans labeled “Asia – Unlimited” give 3GB of high‑speed data per day and throttle the speed to 1000 kbps once that daily limit is reached. Travelers who need larger continuous data allotments can choose fixed‑data options instead, such as the 100 GB plan valid 180 days or the 50 GB plan valid 90 days, which offer higher total data allowances at a fixed rate.

RoameSIM provides several East Asia eSIM plans that include a phone number and SMS. The plans run from 1GB of data for 7 days, priced at $21.00 USD, up to 20GB of data for 365 days, priced at $124.60 USD. Each plan supplies a phone number with the dialing code +1, allowing inbound and outbound voice calls as well as inbound and outbound SMS while traveling in China, Hong Kong, Japan, South Korea, Macau and more than 160 other countries. If you require specific call or messaging capabilities, it is advisable to confirm the details directly with RoameSIM.

RoameSIM’s eSIM offerings include coverage for the following East‑Asian countries: China, Hong Kong, Japan, South Korea, Macau, Taiwan, and Mongolia. For instance, the Discover Global plan lists all seven destinations, while the Asia plan covers China, Hong Kong, Japan, South Korea, Macau and Taiwan, leaving out Mongolia. Each plan’s country list is given in the plan name section of the provider’s catalogue.
