Wiiline eSIM Data Plans for Thailand

Wiiline does not offer a truly unlimited data eSIM for Thailand. Its only “Unlimited” plan for Thailand, named “for Thailand 20 Days Unlimited, ” provides 2 GB per day on 4G/5G networks and reduces speed to 1 Mbps after the daily 2 GB limit is reached, so the data is still capped.

Travelers can instead choose fixed data plans that offer larger allowances, such as the 100 GB plans with 30‑day or 180‑day validity listed for Asia or Global coverage. These plans give a fixed amount of high‑speed data for a set number of days and can be more cost‑effective unless the user requires significantly higher usage.

Wiiline does not provide Thailand eSIM plans that include a phone number or SMS capability. Only data‑only eSIM plans are offered for Thailand.

Travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging, but some destinations may block or restrict access to specific apps or VoIP services, so it is advisable to verify that the apps you rely on are accessible in Thailand before purchasing.

Wiiline provides 12 single‑country plans and 107 multi‑country plans covering Thailand. The catalogue includes both daily data‑cap options and fixed‑data‑cap offerings; 47 plans fall into the former category while 72 are fixed‑data‐cap. Prices for the Thai plans span roughly $1.01 to $160.00, with data caps ranging from 490 MB up to 100 GB.
