As you might be aware, access to your favorite social media platforms and other services can be a little bit tricky in China. While there’s a few different ways around this, the quickest and most reliable way is to get an eSIM for your phone. Roaming with your existing phone is the other option, but data charges can be extreme – eSIMS are just a fraction of the cost, often available at under $1 per day.
These eSIMs are typically Singapore or Hong Kong based, thus they don’t have the same restrictions as mainland-based connections. This means you should be able to access everything you normally can including Facebook, WhatsApp, Instagram, Youtube, Tiktok, Google (search engine), Google Play, Google Maps etc.
Most eSIMS don’t have a phone number, they are data-only. However you can still make app-based calls through WhatsApp, FB Messenger etc, so keeping in touch with your friends at home will be much easier.
Almost all phones from the past few years support eSIMS, and installation is easy. You’ll either get sent a link or a QRcode to scan to install it and after adjusting a few settings you’ll be connected straight away. Typically you install the eSIM onto your phone before you are in China, then activation takes just seconds when your’re there. I typically do it while the plane is still taxiing to the gate.
These days, eSIMs are widely available and are significantly cheaper than roaming. The cost will vary depending on how many days and how much data you need, but they are typically less than $1 per day.
I’ve tested a few different options and all have worked well. You can go with one of the big eSIM apps like Airalo, however they are significantly more expensive than other options. I typically use the eSIM cards from Trip.com as they are the China experts and the cards are incredible cheap. I’ve tested their top 3 selling eSIMs and all have worked excellently. They also give you the option to “renew” the card, i.e. add more data if you’ve run out without having to install a new one.
General FAQ
Which apps and sites will not work in China?
All western social media is inaccessible in China, including but not limited to Facebook, Instagram, Facebook messenger, WhatsApp, Tiktok, Youtube and many more. In addition, most search engines like Google cannot be accessed, although a limited version of Microsoft Bing is available. Generally speaking, anything Google wont work, the most useful ones being Google Maps, Google Translate and Google Play, however Android itself works fine. Besides this, most foreign news sites will be blocked, as with various others. Sometimes sites which aren’t even remotely sensitive can be blocked. Many AI platforms like ChatGPT are also blocked.
I’m already in China, how can I get an eSIM?
Trip.com is accessible in China, they have plenty of options available.
Device & Setup
How do I know if my phone supports eSIMs?
Dial *#06# and your phone will display a bunch of numbers. If you can see one called EID (not MEID) they you phone supports eSIMs.
Can I use an eSIM and my regular SIM card at the same time?
Yes. Most modern phones allow “dual SIM” functionality, which means you can keep your home country’s SIM card active for calls and SMS, while using the eSIM for data.
Do iPhones and Android phones support eSIM differently?
The process is very similar. iPhones tend to have the smoothest installation process, while on Android it can vary a little depending on the brand, but in all cases it’s straightforward.
How do I switch back to my normal SIM after using an eSIM?
You don’t need to delete the eSIM. Just go into your phone’s settings and toggle your regular SIM back to the primary data option.
Do I need to delete the eSIM after I finish my trip?
No, you can leave it installed. If you don’t plan to reuse it, you can delete it from your phone’s settings, but it won’t cause issues if you leave it there.
Coverage & Speed
Will my eSIM have good coverage across China (cities vs rural areas)?
Yes. Since the eSIMs connect via major networks in China, you’ll get strong coverage in all major cities and tourist areas. Rural coverage is more limited, but still generally decent.
How fast is the internet speed with these eSIMs?
In cities you can expect 4G or 5G-level speeds, which are fast enough for streaming and video calls. In smaller towns, speeds may drop but remain usable for everyday browsing and messaging.
Is 5G available on eSIMs in China?
Yes, many eSIMs now include 5G access if your phone supports it. However, coverage outside big cities may still default to 4G.
Usage & Apps
Can I use eSIM data for hotspot/tethering to other devices?
Yes, most eSIMs support hotspot use, so you can share your data with laptops or other phones.
Can I still use my home country number for calls and SMS while using an eSIM for data?
Yes, if you keep your physical SIM active in dual SIM mode. Calls and texts will go through your home SIM, while the eSIM handles data.
Will video calls on WhatsApp/Zoom work smoothly in China with an eSIM?
Yes. Since the eSIM uses networks outside of mainland China’s restrictions, video calls on WhatsApp, Zoom, Messenger, FaceTime etc. work normally.
Purchase & Activation
How early should I buy an eSIM before my trip?
You can buy anytime in advance. Most eSIMs let you install them before travel and only activate when you first connect in China.
Can I activate the eSIM once I’m already in China?
Yes. As long as you have Wi-Fi access (e.g. at your hotel or airport), you can install and activate the eSIM on the spot.
Do I need Wi-Fi to install an eSIM?
Yes, you’ll need an internet connection to download and install the eSIM profile. After that, it runs on mobile data.
What happens if I run out of data—can I top up easily?
Yes. Many providers, including Trip.com, allow you to “renew” or top up your eSIM without installing a new one.
Cost & Validity
How much data do I really need for a trip to China?
This depends on your usage. Light users (messaging, maps, light browsing) can get by on 1–2GB per week. Heavy users (social media, video, streaming) may need 5–10GB per week or more. Trip.com offers options with up to 100GB per day for less than $3 per day.
Are there unlimited data eSIM options?
Yes, some providers offer unlimited packages, though the speed may be throttled after a certain usage limit.
Can I get refunds if the eSIM doesn’t work?
This depends on the provider. Some will refund unused plans if you haven’t activated them, but once activated, refunds are rare.
Practical Concerns
Will using a foreign eSIM affect access to Chinese apps like WeChat or Alipay?
No, WeChat, Alipay and other local apps work fine with foreign eSIMs. You’ll still need to link your account with a valid payment method.
Is an eSIM safer or more secure than public Wi-Fi/VPNs in China?
Yes. Using mobile data is generally safer than relying on public Wi-Fi. With an eSIM, you don’t need a VPN for most Western apps since the connection comes from outside China.
Can business travelers rely on eSIMs for email and work apps?
Yes. Outlook, Gmail (via app), Slack, Zoom and other work tools work normally on eSIMs. Speeds are usually fast enough for business use.
Do eSIMs work at airports in China right after landing?
Yes. If you’ve pre-installed your eSIM, it typically activates within seconds of landing, often before you even reach immigration.
