MobileSIM eSIM Data Plans for Thailand

MobileSIM does not provide a true unlimited data eSIM plan for Thailand. The only plan that carries the word “Unlimited” in its name, Thailand Unlimited data for 10 days, is limited to 3 GB per day; after that limit is reached the speed throttles to 1000 kbps, so it is not a genuinely unlimited offering.

Instead, MobileSIM offers several fixed data plans that cover Thailand. For example, a 20 GB plan valid for 30 days is priced at $18.00 USD, and a larger 100 GB plan with 180‑day validity costs $185.00 USD. These fixed‑data options give travelers a predictable data allowance without the reduced speed applied after an unlimited plan’s limits are reached.

MobileSIM does not provide an eSIM for Thailand that includes a local phone number or the ability to send or receive SMS. All available eSIM options from the provider are data‑only plans.

Travelers can still stay connected by using popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, which allow voice and messaging without a dedicated phone number or SMS support.

MobileSIM offers seven single‑country data plans that include Thailand, along with fifteen multi‑country plans that cover Thailand among other destinations. Prices for these plans start at about $1.50 and can go up to $185, while the data caps span from 200 MB to 100 GB. The provider has one daily‑cap plan, where the data allowance resets each day, and twenty‑one fixed‑cap plans, which grant a set amount of data for the full validity period.
