AlpineSIM does not provide a truly unlimited data eSIM for Thailand. Every plan that appears under an “Unlimited” heading actually contains a daily data cap—ranging from 500 MB up to 10 GB per day—after which the speed may be throttled.
Travelers who need higher data volumes can choose fixed‑data plans instead. For example, AlpineSIM offers a 20 GB eSIM that lasts 30 days for $12.17 USD and a 50 GB eSIM that is valid for either 10 or 180 days (at $11.98 USD and $39.55 USD respectively). These options deliver a larger amount of high‑speed 5G data in a single bundle and can be more cost‑effective compared to the daily‑cap “Unlimited” plans, unless the traveler is an extremely heavy data user.
AlpineSIM does not offer eSIM plans for Thailand that include a phone number or SMS capability. Only data‑only eSIM plans are available from this provider.
Travelers can still use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection for calls and messages without a local phone number.
AlpineSIM provides 10 single‑country plans that include Thailand and 199 multi‑country plans that cover Thailand among other destinations. The available plans range in price from about $0.44 to $296.51, and the data caps span from 100 MB up to 50 GB. For those who prefer a straightforward data allotment, a fixed‑data‑cap plan is offered, while travelers who want more flexibility can choose a daily‑data‑cap plan that allows the data to be used over a set number of days.
