Should I use public Wi-Fi or a CoreESIM in Beijing?

CoreESIM strongly advises against relying solely on public Wi-Fi in Beijing due to inherent inconsistencies in availability, speed, and security. Many public Wi-Fi networks, even in hotels or cafes, often require local phone number verification or have significant bandwidth limitations. A CoreESIM data plan provides a secure, private, and consistently fast connection via China Mobile or China Unicom. This is crucial for maintaining connectivity for essential apps like WeChat, navigating with Baidu Maps, and ensuring secure access to VPN services throughout your stay, from Tiananmen Square to the Great Wall.
