trifa does not provide an unlimited data eSIM plan for Thailand. The plans available from trifa in Thailand come with a fixed data allowance, the largest being 100GB. For example, trifa offers a 100GB plan valid for 3 days at $18.55 USD, a 100GB plan for 5 days at $26.73 USD, a 100GB plan for 7 days at $37.40 USD, a 100GB plan for 10 days at $49.89 USD, and a 100GB plan for 15 days at $74.87 USD. Choosing a fixed data plan can be more cost‑effective for most travelers, unless the user requires an extremely high or unlimited data volume.
