JamboSim eSIM Data Plans for East Asia

JamboSim does not provide a truly unlimited data eSIM for East Asia. The plans that carry the “Unlimited” name give up to 3GB of high‑speed data per day and then throttle the connection to about 1 Mbps.

Travelers who need a larger data allowance can choose from JamboSim’s fixed data plans, such as the 100GB plan valid for 180 days or the 50GB plan valid for 90 days, which offer substantial data limits and may be more cost‑effective for heavy data users.

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.

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.
