ETravelSim does not offer a truly unlimited high‑speed data plan for China. Plans that carry “Unlimited” in the name actually provide a fixed amount of high‑speed data—100GB for 7‑30 days or a 4GB per day allowance for 7‑30 days—and once that limit is reached the connection speed drops to 128kbps.
Customers who need a large data allowance can choose from fixed‑data plans instead. For example, a 50GB plan is available for 30 days at $39.99 USD and a 20GB plan costs $22.99 USD for the same period. These plans give users a substantial amount of data and may be more cost effective than the limited‑speed “Unlimited” options for those who are not extremely heavy data users.
