Simsima eSIM Data Plans for China

Simsima does not provide a truly unlimited data eSIM for China. The plans that include “Unlimited” in their names actually allocate 3 GB of high‑speed data per day and then throttle speed to 1000 kbps once that daily limit is reached, so total data usage does not exceed the cumulative amount of the validity period.

If you need a large amount of data without the daily cap, you can choose one of Simsima’s fixed‑data plans. For example, a 100 GB plan valid for 180 days costs $84.53 USD, and a 50 GB plan for 30 days costs $44.12 USD. These fixed‑data options deliver the full data allowance at high speed throughout their validity period.

Simsima does not provide eSIM plans for China that include a phone number or SMS capability. All available China eSIMs from Simsima are data‑only and lack inbound or outbound voice and SMS services. Travelers who need calls or messages in China can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but it is important to verify that these apps are not blocked or restricted in China before purchasing a plan.

Simsima lists a total of 12 single‑country data plans and 19 multi‑country plans available for China. The catalog includes both fixed‑data‑cap options—as well as plans that reset their allowance daily—providing flexibility for travelers who prefer a set amount of data for the entire validity period or a daily limit that may be more cost‑effective for short stays. Prices for the China‑specific plans range from about $0.40 to $174.93, while the data caps offered span from 100 MB up to 100 GB, allowing users to choose a package that fits their usage needs.
