eSIM and SIM setup for China: keep maps, taxis, and payments working
2026-04-22 · China Travel Today Editorial DeskMost travel friction comes from small breaks: OTP texts that never arrive, map tiles that refuse to load, or ride-hailing logins that require an SMS you cannot receive.
For most travelers, the safest setup is: keep your home SIM active for bank/OTP texts (roaming off most of the time), add a data-only eSIM for maps and messaging, and carry one offline backup (printed hotel address + one local taxi phrase).
Buy plans that publish speed caps and hotspot rules. If you rely on hotel Wi‑Fi alone, you will hit captive portals at the exact moment you need translation or ride pickup.
