Gigapanda does not provide a truly unlimited high‑speed data eSIM for China. All of the China plans have a hard data cap. The plans labelled “Unlimited” give a daily high‑speed allowance of 3 GB for the number of days specified; once that daily allocation is used the connection slows to 128 kbps for the remainder of the validity period.
Instead, Gigapanda offers fixed data plans that can be useful for longer stays, such as the China 50 GB 30‑day plan for $37.90 USD or the China 30 GB 30‑day plan for $26.90 USD. These plans provide a set amount of high‑speed data (50 GB or 30 GB) that is valid for 30 days; after the allowance is exhausted, the speed drops to 128 kbps until the plan expires.
