Short answer: usually yes. On a travel eSIM in mainland China you can normally open Google, WhatsApp, Instagram and YouTube with no VPN. It is not a trick. It is worth understanding why it works, because the same reason explains the things that still fail.
Why it works
A travel eSIM is a roaming SIM. A Chinese network carries your signal, but it does not put you on the Chinese internet. It passes your traffic through a tunnel to the carrier that issued the eSIM, and that carrier releases it onto the internet from its own gateway outside the mainland. Your traffic joins the internet somewhere else, so the mainland's filtering is not in its path. A foreign SIM card roaming in China has always behaved this way.
We covered the mechanism in why your travel eSIM has an IP address from another country. China is where it matters most.
Where our China plans exit
We checked our own catalogue in October 2026. Of the 46 China plans we list, 34 come from a carrier that publishes the exit point. Eighteen of those leave through Hong Kong and sixteen through Singapore. None exits in the mainland. For the other twelve plans the carrier does not publish it.
Hong Kong or Singapore: it matters
Hong Kong has an open internet, so a Hong Kong exit opens the usual list. But several companies refuse Hong Kong addresses themselves. ChatGPT and Claude are not offered there, and TikTok left in 2020. On a plan that exits in Hong Kong those three fail, in Shanghai or anywhere else, and no setting on your phone will change it.
Plans marked Non-HK IP exit in Singapore instead, where all three work. They cost slightly more. If you depend on any of those apps, that is the version to buy. If you only need maps, mail, messaging and search, the Hong Kong version does the job.
| Exit in Hong Kong | Exit in Singapore (Non-HK IP) | |
|---|---|---|
| Google, Gmail, Maps | Works | Works |
| WhatsApp, Instagram, YouTube | Works | Works |
| ChatGPT, Claude | Refused by the provider | Works |
| TikTok | Refused by the provider | Works |
| WeChat, Alipay | Works | Works |
The limits
- Wi-Fi is still the Chinese internet. The moment your phone joins hotel or cafe Wi-Fi, you are behind the filter again. Stay on mobile data for anything that is blocked.
- Some Chinese services want a Chinese address. A few local streaming and booking services limit what they show to connections from overseas. Use Wi-Fi for those.
- Roaming is a little slower. Your data makes a detour through the exit. Fine for browsing, calls and video. You will notice it in fast online games.
- Phones sold in mainland China usually have no eSIM. If you bought your handset there, check before you buy a plan.
- It is not a privacy tool. The local network still sees your device and its location, and the exit carrier still handles your traffic. If you want a VPN as well, install it before you travel.
- Nothing here is guaranteed. This is how roaming works today, not a promise about tomorrow, and the law where you are is yours to follow.
Compared with a local SIM
A SIM bought in China puts you on the filtered internet, so everything above would need a VPN that works there, which is its own project. It also means real-name registration with your passport and a facial scan, one of the ten countries where a local SIM means handing over your passport. A travel eSIM skips both and is installed before you board. It is data only, so you will not get a Chinese phone number, which a few local apps ask for at sign-up.
Before you fly
- Pick a plan on the China page. Choose Non-HK IP if you need ChatGPT, Claude or TikTok.
- Install it before you leave, while you have a normal connection. If your plan starts its clock at install, do it on the day you fly.
- When you land, turn on data roaming for the eSIM and make it your data line.
- Download offline maps and anything else you would hate to lose, in case you spend a day on Wi-Fi only.
