RedSim eSIM Data Plans for China

RedSim does not provide a truly unlimited data plan for China. The plans that carry the name “China Unlimited” give 3GB of high‑speed data per day; once the 3GB daily quota is reached the speed reduces to 1000 kbps. If higher data usage is required, users can choose a fixed data plan such as the 30‑day 50GB offer or the 30‑day 20GB plan, both of which provide a set data allowance that does not change after the set validity period.

RedSim does not provide a China eSIM that includes a phone number or SMS capability. Only data‑only eSIM plans are offered for China.

Travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging. However, some destinations may block or restrict access to specific apps or VoIP services, so it is advisable to verify that the apps you rely on are accessible in China before purchasing a plan.

RedSim offers 22 single‑country plans that include China and 17 multi‑country plans that include China. The plans range in price from about $2.15 to $64.99 and provide data caps from 1 GB to 50 GB. Some plans are fixed‑data‑cap, giving a set amount of data for the validity period, while others are daily‑data‑cap, allowing a certain amount of data each day within the validity period.
