JamboSim eSIM Data Plans for Southeast Asia

JamboSim does not offer a genuinely unlimited data eSIM for Southeast Asia. The plans that carry “Unlimited” in their names provide a daily high‑speed allowance of 3 GB each day; once that daily limit is reached the download speed is reduced to 1000 kbps. This means the data is capped, not truly unlimited.

If you need larger data volumes without throttling, JamboSim provides fixed plans such as the 100 GB plan for 180 days priced at $71.99 USD and the 50 GB plan for 90 days priced at $37.99 USD. Both cover Indonesia, Cambodia, Laos, Malaysia, Philippines, Singapore, Thailand, Vietnam, and 10 additional Southeast Asian countries. These fixed‑data options are the available alternatives for travelers seeking extensive data usage in Southeast Asia.

Yes. JamboSim offers eSIM plans that include a phone number and outbound SMS capability for travelers in Southeast Asia. The plans use a +1 dialing code, which is not a local Southeast Asian number, and allow calls and texts to be sent but not received. Prices range from $11.99 USD for a 1GB, 7‑day plan up to $105.99 USD for a 20GB, 365‑day plan, while validity periods vary from 7 days to 365 days. Users looking for specific calling or messaging functionality should verify the details directly with JamboSim before purchasing.

JamboSim’s eSIM Global and Global+ plans cover Brunei, Indonesia, Cambodia, Laos, Malaysia, Philippines, Singapore, Thailand, Timor Leste and Vietnam, whereas the Asia plan provides coverage in Indonesia, Cambodia, Laos, Malaysia, Philippines, Singapore, Thailand and Vietnam. These plans also extend service beyond Southeast Asia, but only the above countries are mentioned for the region.
