Yes, foreigners can use the internet in China, but with some differences for important considerations.
China has its own internet regulations and infrastructure. While basic internet access is available, many international websites and platforms such as Google, Facebook, Twitter, Instagram, and WhatsApp - are blocked. To access these, visitors often use Virtual Private Networks (VPNs), though it's important to note that using unauthorized VPNs may violate local regulations.
Chinese alternatives like Baidu (search), WeChat (social media), and Alipay (payments) are widely used and can be very helpful for daily needs. Most of hotels, airports, and major public areas offer Wi-Fi, but registration with a phone number or passport may be required.
