trifa does not offer an unlimited data eSIM for Cambodia. Instead, the available options are fixed data plans with set data caps and validity periods. For example, trifa provides a 100GB plan that can be purchased for 3, 5, 7, 10, or 15 days, with prices ranging from about $19 to $78 USD. These fixed plans offer a large data allowance and may be more cost‑effective for travelers who need substantial data but do not require an unlimited bundle.
