MobileSIM eSIM Data Plans for Thailand

MobileSIM does not provide a permanently unlimited data eSIM for Thailand. The plans branded “Thailand Unlimited data” deliver 3GB of high‑speed data per day for the specified validity period; once that daily quota is reached the speed is throttled to 1000 kbps. If a user needs broader coverage on fixed data amounts, MobileSIM offers plans such as 20 GB for 30 days at $18.00 USD or 50 GB for 90 days at $100.00 USD. These fixed‑data plans can be more cost efficient unless a traveler is an extremely heavy data user.

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 data plans and 13 multi‑country plans that cover Thailand. The offerings include both fixed data amount plans—which give you a set volume of data for the entire validity period—and daily data cap plans, which limit how much data you can use each day. Prices across all plans range from about $4.00 to $185.00, while data volumes vary between 1 GB and 100 GB, and validity periods cover 3 to 180 days. Some plans also feature a reduced speed option of 1000 bps.
