How to Get Internet
An eSIM is the simplest way to arrive in China with data already active. Buy it before your flight, activate it at the airport, and your phone works from the moment you land.
An eSIM is a digital SIM card loaded onto your phone before departure. You buy it online, receive a QR code, and activate it at the airport or on arrival. No SIM card to lose, no queues at a phone shop, and no worry about being without data while you figure out logistics.
Purchase from a reputable eSIM provider (Airalo, Nomad, and Holafly are commonly used for China). Scan the QR code in your phone's eSIM settings before departure. On arrival, switch your data to the new eSIM profile. Most China eSIMs provide 5–15 days of data with options to extend.
A China eSIM gives you mobile data in China — it does not give you access to blocked services. You still need a VPN installed on your device before arrival to access Google, WhatsApp, and other blocked platforms. The eSIM and VPN work together.
Most iPhones from XS onwards and many modern Android flagships support eSIM. Check your phone's specs and confirm your carrier has not carrier-locked eSIM functionality. If your phone does not support eSIM, a physical SIM is your alternative.

Your eSIM gives you data — but a VPN is what gives you access to Google, WhatsApp, and other blocked services.
