JamboSim for East Asia FAQ
Does JamboSim offer unlimited data eSIM for East Asia?
JamboSim does not provide a true unlimited data eSIM for East Asia. The plans titled “Unlimited – 3 days”, “Unlimited – 5 days”, etc. actually offer a 3GB/day high‑speed allowance; once that limit is reached the speed drops to 1000 kbps, which means the data is not unlimited in the conventional sense.
For travelers needing a larger data budget, JamboSim offers fixed‑cap plans such as 100GB for 180 days or 50GB for 90 days. These have a fixed data allowance but no speed throttling once the cap is reached. If a user expects heavy, unrestricted usage, a fixed high‑cap plan may be more cost‑effective than the “Unlimited” options.
Does JamboSim offer East Asia eSIM with phone number and SMS?
JamboSim does not provide any East Asia eSIM plans that include a phone number or SMS capability. All of their East Asia offerings are data‑only, so travelers cannot receive or send standard SMS messages or make landline calls with a local number. For voice and messaging, users can rely on VoIP applications such as WhatsApp, Telegram, and iMessage that operate over the data connection provided by the eSIM.
What countries are covered by JamboSim's eSIM plans in East Asia?
JamboSim offers eSIM plans that cover China, Hong Kong, Japan, South Korea, Mongolia, Macau, and Taiwan in East Asia.
