TailSim eSIM Data Plans for China

TailSim does not provide a true unlimited data eSIM for China; every listed plan has a hard data cap. The plans that include “Unlimited” in their name actually provide 2 GB per day of high‑speed data and then throttle the speed to 512 kbps once the daily quota is reached.

Travelers who need a larger, capped allowance can choose one of TailSim’s fixed data plans, such as the 50 GB plan for 30 days or the 20 GB plan for 30 days. These fixed plans deliver a set amount of high‑speed data for the entire validity period and can be more cost‑effective for typical usage.

TailSim does not provide eSIM plans for China that include a phone number or SMS capability. Only data‑only eSIM plans are offered for this destination.

Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some of these services may be blocked or restricted in China, so it is advisable to confirm that the apps you rely on are accessible before purchasing a TailSim plan.

TailSim offers 14 single‑country plans for China and no multi‑country options. Among these, 8 plans feature a daily data cap that resets each day, while 6 provide a fixed data cap for the entire validity period. Prices range from about $3.99 to $82.50, with data limits from 1 GB up to 50 GB and validity durations between 3 and 30 days.
