eSIM for China: online beyond the Great Firewall
An eSIM for China keeps you connected from the Great Wall to Shanghai and Beijing. China is a special case when it comes to the internet, thanks to the so-called Great Firewall, which blocks many Western services. A well-chosen travel eSIM can make life a lot simpler. This guide explains everything with tables, tips and an FAQ.
The Great Firewall and why an eSIM helps
With a local Chinese SIM card, your traffic runs over the national network and stays subject to the blocks. The advantage of a travel eSIM is that your connection, depending on the operator used, can be routed outside China, which reduces or removes those restrictions. Always check this in advance with the provider.
China lies outside the EU, so your home data is expensive there in roaming. An eSIM gives you a set amount of data at a price you know upfront.
Important for China: get everything ready before you leave, using Wi-Fi at home, because some of the services you need for installation are harder to reach once you are there. Ask the provider whether the eSIM offers open access.
