China Telecom offers short-term packages (7 days/15 days/30 days) with data and calls, available with passport registration.
Short-term Stay: Recommend 7-day/15-day tourist cards, including data + calls, priced around 50-100 RMB.
Long-term Use: Choose 30-day packages, some include international calling minutes.
eSIM Plan: If your phone supports it (check EID by dialing *#06#), you can scan to activate a virtual card, eliminating the need for a physical SIM card while supporting cross-border internet.
