China eSIM
China eSIM
China is the one trip where the SIM decides which apps open. Data comes in from outside the mainland, so maps and messaging stay the way you left them, on plans from a single day to a month.

How to check China eSIM Compatibility?

If yes, your phone is eSIM compatible.
How to set up your Olysim travel eSIM in 3 steps
Choose a plan, scan the QR code that lands in your email, and switch the line on when you arrive. Install it on wi-fi before you travel - data only starts counting once you connect at the destination.
Why buy a China travel eSIM from Olysim
Pick the size that fits the trip
A long weekend and a month in China need very different plans, so you choose the data and the days. Around 3GB covers a week of maps, messaging and a daily scroll; 10GB carries a fortnight with video calls home.
Set it up at home, land connected
The QR code arrives by email seconds after payment. Scan it on wi-fi before you leave, and the China line comes alive on its own once you land and switch it on.
Someone answers, any hour
Stuck on the install, or the line will not attach after landing? Message us and a person replies, whatever the hour is where you are.
What is an eSIM and how does a travel eSIM work?
A SIM built into the phone
Phones from the iPhone XS onward, and most Android flagships since 2019, carry an eSIM slot alongside the usual tray. Adding a travel plan writes it to that slot, and your everyday SIM stays where it is.
The QR code is the plan
Scanning the code from your email writes the plan onto that handset. It installs once and stays there, so scan it on the phone you are actually travelling with.
Skip the arrivals counter
Buying a local SIM at arrivals usually means a passport, a form and a queue, in a language you may not read. An eSIM is already on the phone when the wheels touch down.

China eSIM: frequently asked questions
Yes. The data routes through a network outside the mainland, so maps, messaging and the services you already use open the way they do at home.
A mainland SIM routes your traffic inside the mainland, where a different set of services is reachable. This plan comes in from outside, so what opens does not change when you land.
Yes. The plan covers mainland China as one area, so the three big airports and the high-speed line between the cities are all on the same profile.
Yes. Lengths start at a single day and run to 30, so a four-day fair trip does not mean paying for a month.
Any carrier-unlocked phone with eSIM support: iPhone XS or later, Pixel 3 or later, most Android flagships from 2019 on. Check network settings for Add eSIM before you fly.
Yes. Top up from the Olysim app and it lands on the eSIM already installed.

OLYSIM really helps me to travel hassle-free globally. It activates immediately after landing overseas. I travel china often. I couldn’t start my journey without OLYSIM. Data plans offer great value for money compared to other networks.
Very good eSIM and no problems in China, and the network connects best
ekdam fine chaltu tu kai j issue noto avyo best network
First of all, I would like to thank Olysim very much that I had a 15 day trip to China and they provided me with better network data than what I had expected. Thank you very much for that.
I have used Olysim for my recent China trip. I used it for the first time and my experience was awesome. There was no problem in connectivity and the Google App. Now I will carry this card on every trip. Best Experience.
I am absolutely happy with Olysim. I used it in March-April for Germany, found it good, and so used it again for China. The internet speed was also nice. Also happy with the prompt customer service
