MobileSIM eSIM Data Plans for Thailand

MobileSIM does not offer a truly unlimited high‑speed data plan for Thailand. The plans that carry the label “Unlimited” provide 3GB per day and, once that quota is reached, the connection speed is reduced to 1000kbps. Travelers who need more data can choose from MobileSIM’s fixed‑data options, such as the Thailand 20GB plan for 30 days at $18.00 USD or the Asia 100GB plan for 180 days at $89.00 USD. Fixed‑data plans can be more cost‑effective for most users unless the traveler is an extremely heavy data consumer.

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 provides 12 single‑country eSIM plans and 22 multi‑country plans for Thailand. The single‑country lineup consists of daily data‑cap options, whereas the multi‑country choices feature fixed data amounts. Prices range from roughly $2.34 to $89, with data limits spanning 200 MB to 100 GB.
