Best eSIM for China: Register First, Then Use Data On Arrival
The most practical setup for many foreign visitors is to register Alipay, WeChat, and any other essential apps before departure using a phone number that can receive SMS, then use a travel eSIM in China for data only. That way, the eSIM helps you get online on arrival and use the apps you already set up, while the registration step is handled before the trip.

Register your apps before you fly
Before departure, open the apps you actually need and finish the initial signup or identity steps with your own phone number so SMS verification does not become a problem after landing.
This is the point where you should complete Alipay, WeChat, and any other essential travel apps that ask for a verification code. The goal is to arrive with the apps already active, not to start troubleshooting them at the airport.
Use eSIM in China for data, not registration
A travel eSIM is mainly a data connection. Once you land in China, it can help you get online quickly and keep using the apps you already set up before departure.
That means you can often use your familiar software without setting up a separate VPN workflow just for normal browsing and travel tasks.
What the eSIM does not replace
Do not treat an eSIM as a full replacement for a phone number that can receive text messages. If a platform needs SMS verification later, you still need a number that can receive codes.
That may be your original phone number with roaming enabled, or a separate local SIM with SMS support.
When a local SIM still makes sense
A local mainland SIM can still make sense for longer stays, for travelers who specifically want a local number, or for people who expect to rely on SMS-heavy services while in China.
For a short trip, though, it is often simpler to separate the jobs: use your own phone number for app setup before you fly, then use an eSIM for data after you arrive.
A practical recommendation
For most first-time trips, do the app signup and SMS verification at home, install a travel eSIM before departure, and then use that eSIM for data as soon as you land.
This gives you the simplest combination: your important apps are already open, and the eSIM gives you internet access without making you solve mobile setup twice.
