Physical SIM Card

How It Works

Traditional SIM card you insert into your phone.

Pros

• Local phone number: Can receive calls/SMS
• Often cheaper: Especially for more data
• Better coverage sometimes: Local carrier networks
• Top up easily: Convenience stores, carrier shops
• Works on any unlocked phone

Cons

• Must buy in person: Airport or carrier store
• Passport registration: Takes 20-30 minutes
• SIM swap needed: Risk losing home SIM
• Still blocked: Great Firewall applies
• Language barrier: Setup may be in Chinese

Where to Buy

At airport:

• China Mobile, China Unicom, China Telecom counters
• Easy to find
• Tourist-friendly
• Slightly more expensive

In city:

• Carrier stores everywhere
• Cheaper
• More options
• May need Chinese help

Costs

Tourist 7-day	5GB	¥50-80

Important: Neither Bypasses Firewall

Both options:

Exception: Some eSIM providers route through Hong Kong or other countries—may bypass firewall. Check before buying.

Keeping Your Home Number Active

With eSIM

Dual eSIM or eSIM + physical:

• Home SIM stays in phone
• eSIM added for China data
• Receive calls/texts on home number
• Best of both worlds

With Physical SIM

Options:

• Dual SIM phone (keep both)
• Carry second phone
• Forward calls before leaving
• Accept no access to home number

My Recommendation

For Most Tourists (1-2 weeks)

eSIM — Convenient, no hassle, flexible

• Buy Airalo or similar
• Keep home SIM active
• Use VPN for blocked services
• Don't overthink it

For Budget Travelers

Physical SIM at airport — Cheaper for more data

For Longer Stays (1+ month)

Physical SIM — Better value, local number useful

• Top up as needed
• Local number for registrations
• Lower per-GB cost
