eSIM China: prepaid data on China Unicom for Beijing, Shanghai and the high-speed rail network

Arriving in China without working data is harder than almost anywhere else, because so much of daily life runs through the phone: taxis, payments, train tickets, translation, even restaurant menus. Buying a local SIM as a foreigner usually means paperwork at a counter, and home roaming can be costly for a long trip. A China eSIM from GlobaleSIM is bought online, installed over Wi-Fi before you fly and connects automatically when you land in Beijing, Shanghai, Guangzhou or Chengdu, while your own number keeps working on your primary SIM.

Networks and coverage in China

The eSIM China plan connects to China Unicom, the partner network for the whole country. Coverage is excellent across the major cities, in airports and along the high-speed rail corridors that link Beijing, Shanghai, Xi’an, Hangzhou and beyond. Tourist regions such as Guilin, Zhangjiajie and Yunnan are well served in towns and at the main sights. In the deep countryside, on mountain trails and in the far west, reception becomes less consistent, as it does on every network, so download offline maps and translation packs before leaving the city.

Plans, prices and validity

The China prepaid data plan starts from $4 for 1GB and comes in 2GB, 3GB, 5GB, 10GB, 20GB and 50GB sizes. Validity: 1GB is valid for 7 days, 2GB for 15 days, and the 3GB, 5GB, 10GB, 20GB and 50GB plans for 30 days. A short business trip fits in 2GB or 3GB. A two-week tour with navigation, translation, ride-hailing and photo uploads is comfortable on 5GB to 10GB, and long stays, remote work or a family sharing a hotspot are where the 20GB and 50GB plans earn their place. Validity begins when the eSIM first connects in China, so installing at home costs nothing.

Tips for mobile data in China

Set up the local super-apps used for payments and messaging before you travel, because cash and foreign cards are accepted less widely than in many countries, and link them to your card at home over a stable connection. Some international apps and websites are not reachable on Chinese networks, so check ahead which of your usual services work and plan alternatives. Ride-hailing and rail booking are app-driven, and station gates read digital tickets. Hotel Wi-Fi is generally available, but a personal data line is far more convenient when you are out all day.

Calls and a phone number

Data alone is enough for messaging and video calls. Add a voice-minutes bundle (+100, +200 or +300 minutes) and the eSIM includes a dedicated international phone number, US +1 or UK +44, for calls and SMS. In China a phone number helps with hotel confirmations, calling a guide or a driver, and receiving verification codes when you register for apps or services. The data-only plan does not include calling.
