A practical guide to staying connected in Chengdu, covering eSIM and roaming options, local SIM registration, hotel WiFi, offline maps, and app preparation.
Choose your connectivity before arrival
For a short trip, an international roaming plan or travel eSIM that includes China is usually the simplest choice. It keeps your usual apps and maps working in many cases, but coverage, speed, and app behavior vary by provider. A local Chinese SIM is cheaper for heavy data use, but requires passport registration at an official carrier shop and takes time out of your first day.
Set up offline tools
Before you leave, download offline maps, translation packs, and copies of your bookings. Save your hotel address and phone number in Chinese. Apple Maps works reasonably well in China; Google Maps is unreliable for local navigation. For messaging, make sure your family has a way to reach you that does not depend only on an app that may not work on local networks.
Hotel WiFi and local network behavior
Hotel WiFi is common, but it can require a login page and may be slow during peak hours. Some websites and apps that you use at home may not load on a local network. This is not a malfunction; it is how the network is regulated. Use the connection method you arranged before arrival, and do not assume hotel WiFi is equivalent to your roaming data.
Payments, maps, and ride-hailing
Most essential travel services run through Alipay or WeChat. Install and verify them before arrival. DiDi is the main ride-hailing app and also has an international interface; some visitors use it through Alipay instead. Keep a screenshot of your hotel name and address in Chinese for drivers. A local phone number is useful for restaurant reservations but not mandatory for a short trip.
If your connection fails
Have a paper or offline copy of your hotel address, and carry the phone number of your accommodation. If your eSIM stops working, try a manual network selection or restart the phone before buying a new plan. Keep your home SIM active for banking verification if needed. For long stays, a local SIM and a verified payment app are worth the setup time.
