Step 1: Secure Your Firewall-Bypassing eSIM Before You Land
Do not land in China expecting public Wi-Fi or your home carrier to save you. The Great Firewall blocks almost everything Western, and relying on your home country’s roaming will likely cost you hundreds of dollars for terrible speeds.
Buy the Airalo Chinacom eSIM before your flight. Because it operates on the network of China Unicom and China Telecom, it automatically routes your data outside the firewall. You get instant access to your usual apps without the battery-draining hassle of toggling a VPN on and off.
Buy exactly what you need: Grab the 3GB plan for $11.50 if you just need Google Maps and text messaging, or step up to the 10GB plan for $27.00 if you are a heavy social media user. Do not skip the passport upload in the app—Chinese regulations strictly mandate real-name identity verification
⚠️ Local Truth: We scraped the worst tourist nightmares from Reddit so you don’t repeat them.
The SMS Verification Wall: Foreigners get locked out of apps and Wi-Fi networks because they demand a Chinese +86 number. Survival Solution: A travel eSIM will not give you a local phone number. If you desperately need local app integration, you must physically bring your passport to a telecom store and buy a local SIM card
The VPN vs. eSIM Confusion: Exchange students constantly panic about whether they need an eSIM, a VPN, or both. Survival Solution: Airalo automatically bypasses the firewall on mobile data. You only need to buy a VPN if you plan to connect to your hotel or university’s local Wi-Fi network.
The Non-eSIM Hardware Trap: Travelers realize too late their older phones aren’t eSIM compatible. Survival Solution: Rent a Pocket Wi-Fi device for airport pickup or buy a physical local SIM card when you land. If you use a physical local SIM, you must install a reliable VPN before arriving in China to access Western sites.
Frequently Asked Questions
If you cannot use an eSIM, your best alternative is renting a portable Wi-Fi router for pickup at the airport, or bringing an unlocked phone to buy a physical local SIM card when you arrive. Just remember that local SIM cards are subject to the Great Firewall, so you will need a pre-installed VPN to access Google or Instagram.
(Translation: I’m doing a short exchange, do I really need a VPN or does just an eSIM work well?) If you buy the Airalo China eSIM, it automatically routes your traffic outside the Great Firewall on cellular data. You won’t need a VPN while walking around the city, but if you plan to connect to your university dorm or hotel Wi-Fi, you absolutely must have a VPN.
Travel eSIMs like Airalo provide data only and do not give you a Chinese +86 phone number. If you need a local number to pass SMS verification for specific Chinese apps or local Wi-Fi logins, you must do it the old-fashioned way: take your physical passport to a China Mobile or China Telecom shop to buy a physical prepaid SIM.
