ZenSim eSIM Data Plans for China

ZenSim does not provide a truly unlimited data eSIM for China. Their plans that use the “Unlimited” name actually deliver 3 GB of high‑speed data per day and, once the daily quota is reached, the connection speed is reduced.

Travelers who need more predictable usage can consider ZenSim’s fixed‑data offers, such as the 20 GB plans ($33 for 10 days, $36 for 30 days) or the 10 GB plan for 10 days ($21). These fixed data options can be more cost‑effective for most users unless they expect to use an exceptionally high amount of data.

ZenSim offers only data‑only eSIM plans for China; no plans include a local phone number or SMS capability. Travelers can use data‑based VoIP applications such as WhatsApp, Telegram, or iMessage to make calls and send messages over the Internet.

ZenSim offers eight single‑country data plans that cover China, and eight multi‑country plans that include China as part of the package. The available plans range in price from approximately $14 to $89, with data caps spanning 3 GB to 20 GB and validity periods between 10 and 30 days. Some of the plans provide a fixed data amount for the entire validity period, while others offer a daily data cap, giving users flexibility in how they consume their allowance. Tethering is permitted on applicable plans.
