Yes, your CoreESIM provides robust mobile data connectivity in Beijing, enabling full functionality for local applications such as WeChat for communication and Baidu Maps for navigation. For accessing international services like Google, Instagram, or WhatsApp, a Virtual Private Network (VPN) is essential due to China's internet regulations. CoreESIM provides the underlying data connection; however, you must install and configure a reliable VPN service on your device before your trip. Ensure your chosen VPN client is pre-installed, as downloading it within China may be challenging.
