ZenSim eSIM Data Plans for China

ZenSim does not provide a truly unlimited high‑speed data eSIM for China. The plans that include “Unlimited” in their name grant 3 GB per day at full speed; once that daily limit is reached the connection speed is reduced. For travelers who need more data, ZenSim offers fixed‑data options, such as the 40 GB plans valid for 30 days and the 20 GB plans valid for 10 or 30 days. Choosing a fixed data plan may be more cost‑effective for users who anticipate heavy data usage.

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 provides 9 single‑country plans that cover China and an additional 9 multi‑country plans that include China. The plans span a price range of $14 – $89, with data limits from 3 GB up to 40 GB and validity periods of 10 to 30 days. Some offerings use a fixed data cap, while others apply a daily data cap that refreshes each day. Tethering is permitted on selected plans.
