ZenSim eSIM Data Plans for China

ZenSim does not provide truly unlimited high‑speed data eSIMs for China. The plans marked “Unlimited” actually allow 3 GB per day, after which the service speed is throttled.

The provider offers fixed‑data options that may be more suitable for travelers needing larger data allowances. For example, a 20 GB plan is available for 10 days at $32 USD and for 30 days at $36 USD. These plans give a larger amount of high‑speed data up to the stated cap, which can be more cost‑effective for most users.

ZenSim does not provide China eSIM plans that include a phone number or SMS capability. All ZenSim eSIMs for China are data‑only.

Travelers who need to communicate while in China can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection to make calls and send messages without a local phone number or SMS service.

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.
