What is an eSIM?
An eSIM is a digital SIM built into your phone. Instead of collecting a plastic card, you buy a plan online and install it as a profile, which means you can be connected the moment you land rather than hunting for a shop at the airport. Your physical SIM or home eSIM can stay active at the same time, so you keep your usual number for calls and texts while a travel plan handles your data. For a fuller explanation, see our guide to what an eSIM is.
Is my device compatible?
Most phones released in recent years support eSIM, including current iPhones and many Android handsets, though a few models sold in specific markets do not. Check the setting on your device, where you will usually find an option to add an eSIM or a mobile plan, before you buy. Your phone also needs to be unlocked to use a travel eSIM. If you are unsure, our device compatibility guide walks through how to confirm it.
Saily's China eSIM plans
Saily offers data plans that cover China, and you choose the one that matches your trip:
- Local plans cover China specifically and suit a single-country visit.
- Regional plans cover several nearby countries, which is useful if China is one stop on a wider Asia route.
- Global plans stretch across many countries and suit long, multi-region journeys.
Pick the plan by where you are going and how much data you expect to use. If you are visiting Hong Kong or Macau on the same trip, check the plan's coverage carefully, as they are often treated separately from mainland China.
How to purchase and install your eSIM
- Open the Saily app or website and choose a China plan.
- Complete the purchase and follow the installation prompt.
- Install the eSIM profile while you still have a reliable connection at home.
- Label the line clearly so you can find it easily once you land.
- Turn on data roaming for the Saily line when you arrive and set it as your data line.
Doing this before departure means you are connected as soon as your plane touches down, with no need to find a local counter or borrow airport wifi.
Tips for staying connected in China
China manages its internet differently from many countries, and access to some international apps and websites can be limited on local networks. Because a travel eSIM connects you as a roaming visitor, your data may route through international networks, which can change which services are reachable. No plan can guarantee access to any specific app, so plan ahead:
- Download offline maps and translation packs before you travel.
- Save key addresses in Chinese characters to show taxi drivers.
- Set up the messaging apps you rely on while you are still at home.
- Keep a note of your accommodation details offline in case data drops.
A travel eSIM also sidesteps the local SIM registration counter, which can save time on arrival. For a wider pre-trip checklist, see our connectivity checklist.
Frequently asked questions
Does an eSIM work in China?
Yes. A travel eSIM from a provider that covers China gives you a data connection as a visitor, and you can have it installed before you arrive.
Will an eSIM let me access blocked websites in China?
Not necessarily. Roaming data can route through international networks, which may change what is reachable, but no plan guarantees access to any specific service. Set up the apps you need before you travel.
Is my iPhone eSIM compatible for China?
Most recent iPhones support eSIM. Check the mobile settings on your device and make sure the handset is unlocked before you buy a plan.
Can I keep my home number while using a China eSIM?
Yes. Your physical SIM or home eSIM stays active for calls and texts while the Saily line handles your data, so you do not lose your usual number.
When should I install the China eSIM?
Install it before you fly, while you have a stable connection, then switch it on when you arrive. Installing on arrival is harder without existing data.
How much data do I need for a trip to China?
It depends on your usage. Our guide on how much mobile data you need for two weeks gives a realistic starting point.
Do I need to register an eSIM in China?
A travel eSIM avoids the local SIM registration counter that physical cards can require. Always follow the current rules that apply to your plan and device.
Does an eSIM cover the whole of China?
Coverage follows the partner networks the provider uses. Major cities and populated areas are generally well served, while remote and mountainous regions can be patchier.
Can I share my China eSIM as a hotspot?
Many plans allow tethering so you can share data with a laptop or a travelling companion. Check the plan details before you rely on it.
