Shanghai has one of the densest 5G networks in the world. China Mobile, China Unicom, and China Telecom all operate 5G across the city. The Bund waterfront, Lujiazui financial district (Pudong), People's Square, Nanjing Road pedestrian street, and the French Concession (Xuhui and Luwan) all have full 5G outdoor coverage. HelloRoam connects via China Mobile, which has the widest 5G footprint in Shanghai.
Shanghai Pudong International Airport (PVG) has 5G in both the T1 and T2 terminals. Shanghai Hongqiao Airport (SHA) and Hongqiao Railway Station also have 5G. The Maglev train from Pudong Airport to Longyang Road station has 5G along the route. The Shanghai Metro network has 4G and 5G at all stations and in the tunnels on most lines through the distributed antenna system investment.
The French Concession area around Huaihai Road, Yongkang Road, and Tianzifang arts lane all have dense 5G. Tianzifang's narrow lanes maintain usable 4G. Old Town (Nanshi) near the Yuyuan Garden has 4G and 5G at the main tourist areas. Zhujiajiao water town on the city outskirts has 4G in the main canal area.
Important note: China's Great Firewall blocks many international apps including Google services, Facebook, Instagram, WhatsApp, and Twitter by default. A VPN is needed to access these services. Your HelloRoam eSIM provides fast data, but app access depends on your device's VPN. Set up a VPN before entering China. Singapore-based travellers should verify their handset supports the local 4G and 5G bands.
