JamboSim eSIM Data Plans for East Asia

JamboSim does not provide a truly unlimited data plan for East Asia. The plans branded as “Unlimited” actually grant 3 GB per day and, once that amount is reached, the connection is slowed to 1000 kbps.

Travelers who need more data without a speed reduction can select one of JamboSim’s fixed‑data options. For example, the 20 GB plan for 30 days, the 50 GB plan for 90 days, or the 100 GB plan for 180 days all cover the same East Asian countries and can be more cost‑effective unless you are a very heavy data user.

Yes, JamboSim offers East Asia eSIM plans that include a phone number and SMS capability. The available plans range from 1GB for 7 days to 20GB for 365 days, with prices between $11.99 and $105.99 USD. Each plan provides a phone number with the dialing code +1, allowing outbound calls and outbound SMS. The numbers are not local to East Asia but are US/Canada numbers, so callers can place and receive calls and send and receive SMS to and from that number. Users who need specific call or SMS features should confirm details directly with JamboSim before purchasing.

JamboSim’s coverage in East Asia is available through three plans. The eSIM JamboSim Global plan covers China, Hong Kong, Japan, South Korea, Mongolia, Macau, and Taiwan. The eSIM JamboSim Asia plan covers China, Hong Kong, Japan, South Korea, Macau, and Taiwan. The eSIM JamboSim Global+ plan covers China, Hong Kong, Japan, South Korea, and Macau.
