Yes, Earth Esim offers several unlimited data eSIM plans that cover China. The unlimited plans are available in 1‑day, 3‑day, 5‑day, 7‑day, 10‑day, 15‑day, 20‑day, 30‑day, and longer validity options, with prices ranging from about $1.99 USD for a 1‑day plan to $70.50 USD for a 30‑day plan. All unlimited plans allow tethering and include a Fair Usage Policy, meaning speeds may be reduced after heavy usage. The maximum speed specified for each plan ranges from 1 000 kbps to 10 000 kbps; actual speeds under the Fair Usage Policy may be lower. If you need to confirm whether a specific speed limitation will apply to your usage, contact Earth Esim for the latest details.
