MobileSIM eSIM Data Plans for Thailand

MobileSIM does not provide a truly unlimited data eSIM for Thailand. All plans marketed as “Unlimited” offer a daily cap of 3GB, after which high‑speed data is throttled to 1000kbps. Travelers who want truly unlimited high‑speed usage will need to look elsewhere or use a fixed‑data plan.
For example, MobileSIM offers a 20GB plan for 30 days priced at $18.00 USD and a larger 100GB plan for 180 days costing $89.00 USD. These fixed‑data options give users a clear amount of high‑speed data, which can be more cost‑effective for most travelers than the capped “Unlimited” offers.

MobileSIM does not provide Thailand eSIM plans that include a phone number or SMS capability. Travelers who need data connectivity in Thailand should choose one of MobileSIM’s data‑only eSIM options, which offer internet access but do not allow regular voice calls or standard SMS messages.

After activation, users can still communicate through popular VoIP applications such as WhatsApp, Telegram or iMessage over the data connection. However, some destinations may block or restrict specific apps or services, so travelers should check that the VoIP services they rely on are accessible in Thailand before purchasing a plan.

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.
