JamboSim eSIM Data Plans for Thailand

JamboSim does not provide a truly unlimited high‑speed data eSIM for Thailand. All of its plans labeled “Unlimited” give 3 GB of high‑speed data per day and, after that amount, speed is throttled to 1000 kbps. For travelers who need more data, JamboSim offers fixed data plans such as 20 GB for 30 days, 50 GB for 90 days, and 100 GB for 180 days, which provide higher overall data allowances without a speed reduction. These fixed‑data options can be more cost‑effective for heavy data users compared to the limited‑daily “Unlimited” plans.

JamboSim does not provide a Thailand eSIM that includes a phone number or SMS capability. The provider’s Thailand plans are data‑only, offering high‑speed internet without inbound or outbound voice or text service. Travelers who need to make calls or send messages can use internet‑based applications such as WhatsApp, Telegram or iMessage over the data connection, eliminating the need for a local phone number or SMS features.

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.
