Carrier Comparison
China has 3 state-owned mobile carriers. China Unicom is the most recommended for foreigners — its WCDMA and LTE bands align with international phone models, so most unlocked phones work without issues. Urban coverage is strong, and major city stores often have English-speaking staff.
China Mobile has the widest coverage with over 970 million subscribers, especially in rural and mountainous areas. Some overseas phone models lack TD-LTE support, resulting in slower data or no signal.
China Telecom offers the most competitive pricing in Guangdong Province and the Pearl River Delta, with plans starting from RMB 25 per month. Its CDMA-based network is not supported by some foreign phone models.
Airport SIMs charge ~RMB 100 for 7 days (30 GB + 100 minutes). City stores offer plans from RMB 30–100 per month with far better per-GB value. For stays over 1 month, buy at a city store.
Prepaid vs Postpaid
Prepaid plans need only a passport, no Chinese bank account. Top-ups are available at carrier stores, convenience stores, or via the carrier app. Over 90% of first-time visitors choose prepaid.
Postpaid plans offer better value for heavy data users — approximately 30–50% lower per-GB rates — with international roaming and monthly billing. They require a Chinese bank account or credit card for auto-payment plus a credit check. Prepaid plans can convert to postpaid later.
Real-Name Registration and WeChat 2026 Rules
Since December 2019, all SIM cards require real-name verification with biometric facial recognition under MIIT regulations. One passport can register up to 5 SIM cards across all carriers. Passports under 6 months validity are rejected by all 3 carriers.
In 2026, WeChat introduced a policy requiring real operator-issued Chinese SIM cards. Virtual numbers, VoIP numbers, and international eSIM data-only plans (Airalo, Holafly) are blocked. Alipay offers an alternative via TourCard (foreign passport + international credit card), but apps like Meituan, Didi, and 12306 still require a verified Chinese number.
A Chinese SIM cannot access Google, YouTube, WhatsApp, or Facebook. A VPN installed before arrival is the only way to access these 4 platforms in China.
