trifa does not provide an unlimited‑data eSIM for China. The available China plans are fixed‑data packages that give 100 GB of high‑speed data for a limited period. For example, a 100 GB / 3d plan costs $18.54 USD, and a 100 GB / 10d plan costs $49.86 USD. Choosing a fixed data plan can be more cost‑effective for most travelers, unless an exceptionally heavy data user prefers an unlimited option.
