If you're preparing to set foot in China, you'll already know that internet access is a real headache. It's not just a matter of having data, but also of being able to bypass the infamous Great Firewall , that censorship system that shuts you down when using Google, WhatsApp , or Instagram. To avoid running around Shanghai like a headless chicken, the best solution is to bring a pre-set-up solution from home.
The truth is, there's a lot of conflicting information out there, but the key is choosing between the convenience of a modern eSIM and the reliability of a physical SIM. For a trip of a couple of weeks, the smartest thing to do is look for something that lets you connect instantly as soon as you get off the plane, thus avoiding queues and misunderstandings in local shops where English is rarely spoken.
What exactly is an eSIM with integrated VPN?
Many people get confused about this, but just because an eSIM says it has a VPN doesn't mean it has an app installed on your phone. They actually use a trick called international routing . Basically, even if your phone connects to a Chinese cell tower, the data takes a detour and reaches the internet through another country, like Singapore or Hong Kong. This way, the Chinese government thinks you're browsing from abroad and lets you use your social media and Gmail without any problems.
This option is the simplest because you don't have to configure servers or struggle with apps that the Chinese government constantly tries to block. However, there's an important detail: this system only works with mobile data. The moment you connect to hotel or airport Wi-Fi, you're subject to local censorship again, so you would then need a traditional VPN installed on your device.
Comparison of eSIM providers
There are several brands that dominate the market, each with its pros and cons depending on what you are looking for:
- Holafly: It's probably the most complete option for those who don't want any hassle. They offer unlimited dataThey include bypassing censorship and have Spanish support via WhatsApp, which is a lifesaver if something goes wrong.
- UPeSIM: A highly competitive alternative that uses the network of China UnicomTheir plans are prepaid and very transparent, ideal for short stays with prices starting at €4,99.
- Saily and Nomad: They are cheaper and lighter options, but be careful, many of these VPN not includedTherefore, you would need to install a separate application before traveling.
- Trip.com: Highly recommended by users on forums, as their eSIMs are usually cheap and work very well to bypass geographical restrictions.
Alternatives to eSIM: Physical SIM cards and Pocket WiFi
If your phone is an older model or simply doesn't support eSIM, don't worry, there are other options. You can buy a physical SIM card on Amazon before leaving Spain; many of these come pre-configured to connect via Hong Kong and automatically bypass censorship. Another option is to buy a local SIM card upon arrival, but this is venturing into more complicated territory. You'll have to present your passport, deal with the language barrier, and most likely, it won't have a VPN , forcing you to install an app like Surfshark or Mullvad beforehand.
As for Pocket WiFi, these are the little devices that create a network for several mobile phones. They're useful for families, but the downside is that they need to be charged daily and, usually, they don't include censorship bypass unless you pay extra or configure the VPN yourself on each connected device.
Essential apps and golden tips
To survive in China, the internet is only half the battle. You need local tools because Google Maps isn't the most reliable there. We recommend installing Amap or Baidu Maps to get around, and especially Alipay or WeChat . Cash is practically obsolete in China; everything is paid for with your mobile phone. It's vital that you link your bank card to Alipay before you arrive , as you might need an SMS from your bank to verify your account, which is easier to receive in your home country.
For transportation, the Didi app is the Chinese version of Uber and is essential to avoid relying on taxis that don't speak English. If you decide to use your own VPN for Wi-Fi, install apps like Surfshark, NordVPN, or Mullvad . A key tip: download and install everything before leaving home, because once you're in China, accessing the Play Store or App Store without an active connection is practically impossible.
Having reliable connectivity in China depends on anticipating firewall issues, whether by opting for the simplicity of an eSIM with international routing like Holafly or UPeSIM, or by securing a physical SIM with a robust VPN pre-installed. The key is not to arrive at the airport without a plan, as having data and access to payment apps like Alipay from the very first minute makes all the difference between enjoying your trip and spending hours frustrated in a terminal trying to get a working signal.
