ChillaxSIM eSIM Data Plans for Thailand

ChillaxSIM does provide unlimited data eSIMs for use in Thailand.
The plans span from 1 day to 30 days and range in price from $2.90 USD for a single‑day plan to $38.90 USD for a 30‑day plan. All unlimited plans support tethering and operate on 4G and 5G networks, though the stated maximum speed may be throttled.

ChillaxSIM applies a fair‑usage policy to its unlimited offerings; after significant data consumption the speeds may be reduced. Travelers who require consistent high speeds should contact ChillaxSIM directly to confirm the policy limits and the typical data volume that remains at normal speed.

ChillaxSIM does not provide an eSIM plan for Thailand that includes a phone number or SMS capability. The provider only offers data‑only plans for that destination. Travelers wishing to make calls or send messages can use VoIP applications such as WhatsApp, Telegram, and iMessage, which operate over the data connection and do not require a local phone number or SMS service.

ChillaxSIM offers 15 single‑country data plans for Thailand, and 5 multi‑country plans that also cover Thailand. The overall portfolio ranges from about $2.90 to $45.90 and includes data caps from 3 GB up to unlimited, with different validity durations and daily data limits. Some plans support tethering, while others may see speed throttling to 128 kbps when higher speeds are exceeded.
