JamboSim eSIM Data Plans for Thailand

JamboSim does not provide a truly unlimited data eSIM for Thailand. The plans that carry “Unlimited” in their names actually give 3GB per day and apply a reduced speed of 1000kbps once that limit is reached.

For travelers who need more data, JamboSim offers fixed‑data options. A 20GB / 30 days plan is available for $10.99, and a larger 100GB / 180 days plan can be purchased for $71.99. These alternatives give a larger data allowance and may be more economical for heavy‑usage users.

JamboSim offers several eSIM plans that include a phone number for use while traveling in Thailand. The plans range from 1GB for 7 days at $11.99 USD to 20GB for 365 days at $105.99 USD. The phone numbers come with the dialing code +1, so the number is not a local Thai number but is usable for international outbound calls. Calls can be made from the eSIM, but inbound voice calls are not supported. SMS can be sent, but you cannot receive SMS messages on the number. The plans provide outbound voice and SMS capabilities and do not allow inbound voice or SMS. Travelers who need specific functionality are encouraged to confirm the details directly with JamboSim.

JamboSim’s offerings for Thailand include 12 single‑country plans covering between 200 MB and 100 GB for 3 to 365 days, with prices ranging from $1.99 to $94.99. In addition, 33 multi‑country plans are available that provide the same data and validity ranges. The catalog contains both fixed data‑cap options and daily data‑cap options—33 plans with a predetermined data amount for the whole plan period and 12 plans that reset a daily data limit, offering flexibility for short‑term travelers.
