Purchasing a China SIM card is one of the first things you'll need to do when visiting the country. Here is a guide on how to purchase and use China SIM cards during your trip:

Decide on a Mobile Network Provider

There are 3 main mobile network providers in China – China Mobile, China Unicom, and China Telecom. China Mobile has the best coverage nationwide among them.

Purchase a SIM Card from the Provider

Visit a branded store of the provider you chose and purchase either a prepaid SIM card or a mobile plan package. You'll need to present your passport and accommodation details for registration. SIM cards cost around 30 yuan with an initial top up. Popular prepaid plans range from 80-300 yuan per month with data and call allowances.

Activate and Insert the SIM Card

Follow the instructions to activate your SIM card. On iPhone, go to Settings > Cellular > SIM PIN Management to set the PIN. Insert the nano-SIM into your phone and restart it. Your device should detect the new network.

Set Up Mobile Data

Go to Settings > Cellular or Mobile Network and ensure cellular/mobile data is switched on. Select the correct APN settings for your provider. For China Mobile use 'cmnet'.

Top Up Credit

Top up credit using WeChat Pay by searching for‘手机充值’ and entering your number. Top up amounts at post offices, convenience stores using scratch cards, or carrier stores. Keep enough credit for calls and data usage.

Understand Plans and Usage

Familiarize yourself with your plan allowances and rates for overuse. Check balances by texting special codes to 10086. Roaming networks can help bypass censorship but cost more for usage.

Troubleshooting Connectivity Issues

If you encounter network connectivity issues or have trouble accessing data services, restart your device, reinsert the SIM card, or manually select a network operator in your device settings. Contact the mobile operator's customer support for further assistance if problems persist.
