왜 중국에서 외국인 휴대전화의 데이터가 작동하지 않나요?
Last updated:
⚠️ SYMPTOM
외국 SIM에 신호 막대가 표시되지만 모바일 데이터가 작동하지 않거나, "데이터 로밍 계약 없음(no data roaming agreement)"이라는 SMS를 받았습니다.
🔍 MOST LIKELY CAUSE
본국 통신사에 중국 로밍 계약이 없거나 회선에서 데이터 로밍이 비활성화되어 있어, 신호가 잡혀도 본국 네트워크에서 데이터가 차단됩니다.
✓ HOW TO FIX
공항에서 China Unicom 또는 China Mobile 관광용 eSIM / 선불 SIM을 구매하거나, 도착 전에 본국 통신사에서 유료 일일 로밍 패스를 활성화하세요.

SIM & eSIM
Tourist eSIMs from Airalo, Holafly, and Nomad give 7–30 days of China data for $5–$30 without passport registration at a Chinese store.
Portable WiFi
Rent a portable 4G/5G WiFi hotspot at the airport for ¥30–80/day, returnable at any major airport, useful for groups of 2–4 travelers.
VPN for China
Astrill, LetsVPN, and NordVPN are the most reliable VPNs in China in 2026; install before arrival because the App Store blocks downloads inside China.
