Simsima eSIM Data Plans for China

Simsima does not provide a truly unlimited data eSIM for China. The plans that carry the name “Unlimited – 7 days” and “Unlimited – 30 days” actually allow 3GB of high‑speed data per day and then throttle the speed to 1000kbps after that daily limit is reached, so the data is capped.

Travelers who need more data can choose from Simsima’s fixed data plans that are available for China. For example, the China 50GB 30Days plan offers 50GB of high‑speed data for 30 days, and the China 20GB 30Days plan provides 20GB for the same period. These fixed plans give a larger data allowance without the daily cap and can be more cost‑effective unless a user requires very heavy data usage.

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 offers 12 single‑country plans for China and 9 multi‑country plans that include China. The plans range in price from roughly $1.50 to $84.83 and provide data caps between 100 MB and 50 GB, with validity periods spanning 7 to 365 days. Within the catalogue, six plans use a daily data cap that resets each day, while fifteen use a fixed data amount that is available for the entire validity period.
