The short answer
- Google, WhatsApp, LINE, Facebook and Instagram do not work on Chinese mobile networks or most Chinese Wi-Fi.
- Roaming or an international eSIM usually routes data outside mainland China, so those apps keep working.
- Install the eSIM at home, while you still have Wi-Fi.
- Keep your home SIM active for bank one-time passwords.

Why your usual apps may stop working
Mainland China blocks many foreign services, including Google, WhatsApp, LINE, Facebook and Instagram. Data from your home carrier's roaming, or from an international eSIM, is usually routed outside mainland China, which is why those apps keep working for most visitors.
Setting up an eSIM
- Check that your phone supports eSIM and is unlocked.
- Buy and install the eSIM at home. Activate it when you land.
- Choose a plan with enough data for maps, translation and calls.

Questions
Does WhatsApp work in China?
Not on Chinese mobile networks or most hotel Wi-Fi. Travellers usually keep it working with roaming from their home carrier or an international eSIM.
Should I buy a Chinese SIM card?
A Chinese SIM gives you a local number, which some apps and bookings ask for, but it will not open blocked apps. Many visitors use an international eSIM for data and add a Chinese number only if they stay longer.
How much data do I need?
One to two gigabytes a day is comfortable for maps, translation, payments and video calls.
