The Mainland China plans in our database use China Unicom, CMCC. Where a provider hasn't published it, the table shows "Network not published". A Mainland China eSIM doesn't cover Hong Kong or Macau, so you need to buy those separately. With Airalo's China eSIM, your IP address may show as outside China.
For maps, messaging and light browsing, about 0.3–0.5GB a day, so 3–5GB is enough for 7 days. If you often watch videos or share a hotspot, consider unlimited data. To save money, choose Airalo 50GB · 30 days, the best value per GB (US$0.98 / GB).
Most providers don't list hotspot limits in their details, so please read the plan details before you buy. A travel eSIM is data only and works alongside your own SIM, so WhatsApp keeps working. Calls and SMS to your usual number still go through your own carrier (roaming charges may apply).
In Mainland China, services such as Google, WhatsApp and Instagram are generally not available on local networks. Many travel eSIMs work as international roaming, so your data is routed through networks outside Mainland China and these apps usually work. This depends on the provider, so check the plan details before you buy. Your IP address may show as outside China, and this applies only when you use the eSIM's data, not hotel Wi-Fi. A Mainland China eSIM doesn't cover Hong Kong or Macau.
