ZenSim eSIM Data Plans for China

ZenSim does not have plans that provide truly unlimited high‑speed data for China. The only plans labeled “Unlimited” give a daily allowance of 3 GB; once that daily limit is reached the speed drops to a reduced rate of 1000 kbps, so the service is not unlimited.

Travelers who need a large, predictable data allowance can choose ZenSim’s fixed data plans. For example, the 40 GB plan for 30 days costs $63.00 USD for the Asia+ version and $69.00 USD for the China‑specific version, while the 20 GB plan for 15 days is $32.00 USD (Asia+) or $33.00 USD (China). These plans provide a fixed amount of high‑speed data within the stated validity period, making them more cost‑effective for most users compared to the “Unlimited” names that actually enforce a daily cap.

ZenSim does not provide China eSIM plans that include a local phone number or the ability to send or receive SMS. The only China eSIM offerings from ZenSim are data‑only plans, which give high‑speed internet but do not support traditional voice or SMS services. Travelers who need voice or messaging would typically rely on data‑based VoIP apps such as WhatsApp, Telegram, or iMessage while connected to the China eSIM. Availability of these apps can vary, so it is advisable to check whether the specific services you rely on are accessible in China before purchasing a ZenSim eSIM plan.

ZenSim offers 13 single‑country plans for China and 18 multi‑country plans that include China. Across these options, prices run from roughly $5 USD to $119 USD, while data caps range between 1 GB and 40 GB and validity periods span 5 to 90 days. The provider also supplies 6 daily‑data‑cap plans, which limit data usage each day, and 25 fixed‑data‑cap plans that provide a fixed amount of data for the entire duration of the plan.
