Your China & Hong Kong eSIM in two questions
Which China & Hong Kong eSIM plan fits my trip?
Every plan here gives you 3 GB a day, so the length of your route does the choosing.
- A three-day Shanghai and Hong Kong trip: 3 GB a day for 3 days suits standard use (about 2.1 GB in all), and heavy use (about 5.4 GB in all) still fits.
- A week from Beijing through Chengdu to Hong Kong: 3 GB a day for 7 days suits standard use (about 4.9 GB in all) and heavy use (about 12.6 GB in all).
- Guangzhou and Hong Kong over two weeks: 3 GB a day for 15 days suits standard use (about 9.8 GB in all).
- Hong Kong only: the Hong Kong eSIM suits a trip to Hong Kong alone, with Uber and HKTaxi for rides.

Using one eSIM across China & Hong Kong: tips
- Two places, two sets of apps: On the mainland, use DiDi for rides, WeChat for messages and Baidu Maps or Amap (Gaode) for directions, since Google Maps is unreliable there. In Hong Kong, use Uber or HKTaxi for rides and WhatsApp for messages.
- Blocked in China: Google services, WhatsApp, Instagram, Facebook, YouTube and X (Twitter) are all blocked, so sign in to any apps you need before you arrive.
- Install at home, roaming on: Set up your eSIM before you leave, then turn on data roaming and leave it on at every border crossing between the two.
- Keep your home number: Read how to keep WhatsApp and your home number before you fly, so people back home can still reach you.
- Top up mid-trip: Every plan can be topped up, so if your data runs low partway through, add more to the same eSIM.
