中国 eSIM

Usually not. On mainland-China handsets (国行), the eSIM function is restricted to the three domestic operators. A foreign travel eSIM profile cannot be written to the device at all.

This is a device-level restriction, not a signal or settings problem. The install simply fails or the profile never appears. No amount of troubleshooting changes it, and it is not something a provider can fix remotely.

Hong Kong, US, European and other international models of the same phone do not have this limitation. If you are unsure which model you have, check before buying any travel eSIM — we would rather lose the sale than have you pay for something your phone cannot install.

No, popular international calling apps like WhatsApp and FaceTime are generally blocked in mainland China and require a reliable VPN to function.

Due to China's 'Great Firewall,' many foreign-based communication services, including WhatsApp, FaceTime, Instagram, Facebook, and Google services, are inaccessible. This means that even with a local SIM or an eSIM providing data connectivity, these apps will not work without an additional solution.

To use these apps for video or voice calls, you will need to install and activate a robust Virtual Private Network (VPN) *before* you arrive in China. Ensure your chosen VPN is known to work reliably in China, as many VPN services are also blocked. Your eSIM will provide the necessary data connection, automatically connecting to the strongest available major network like China Mobile or China Unicom, though the exact network may vary by your specific plan.

答案： Cellesim 与中国最大、最可靠的网络提供商合作，例如中国移动或中国联通。这可确保您不仅在北京或上海等大城市，甚至在长城或农村地区也能获得高速 4G/5G 连接。 

答复：请检查具体计划详情。如果您购买的是“仅限中国大陆”套餐，则通常不涵盖香港或澳门。如果您的行程包括这些地区，我们强烈建议您选择我们特定的“中国、香港、澳门”套餐或“亚洲地区”计划，以确保跨境不间断连接。 

答案：是的，绝对如此。通过 Cellesim 互联网连接，您可以顺利使用微信、支付宝和滴滴（出租车）等基本本地应用程序，这些应用程序对于中国境内的日常支付和交通至关重要。 

不，Uber 不在中国运营。您需要可靠的数据才能使用滴滴出行（通常通过支付宝访问）预订行程，更重要的是，使用应用内翻译功能与司机沟通。 

是的。慕田峪和八达岭等最受欢迎的修复地段的覆盖范围出人意料地强大，您可以立即从瞭望塔进行视频通话或上传照片。 

一般来说，是的。在北京和上海等城市之间旅行时，您将拥有 4G/5G 连接，尽管当火车经过长隧道或山区时信号经常中断。
