Wiiline does not provide a true unlimited data eSIM for China. Plans that include “Unlimited” in the name actually give a set amount of high‑speed data—such as 1 GB, 2 GB, or 3 GB per day—with a throttled speed of 384 kbps after the limit is reached; this is a fixed data plan rather than an unlimited one.
Travelers who need more data can choose from Wiiline’s fixed data plans. For example, a 3 GB/day bundle for 3 days costs $4.99, while a 1 GB/day bundle for 7 days is priced at $4.99. If larger volumes are required, Wiiline offers 100 GB plans valid for 30 or 180 days at $106.99 to $129.99. These fixed plans can be more cost‑effective unless a traveler expects very heavy data usage.
