When traveling to mainland China, it's important to be aware that many popular international communication apps and websites, including WhatsApp, Line, Facebook, Instagram, and Google services, are typically blocked by the 'Great Firewall.' This restriction applies regardless of your SIM or eSIM. To maintain access to these services and a free internet experience, EastESIM strongly recommends using a Virtual Private Network (VPN). Our data plans ensure you have a fast, reliable connection through local carriers like China Mobile or China Unicom, which is essential for your VPN to function effectively and keep you connected to your preferred apps.
