6. Key Precautions Before Buying and Using a SIM Card

Regardless of which method you select, ensure you check these 3 critical points in advance:

1. Verify if your smartphone is SIM-unlocked: Devices locked to home carriers cannot use third-party SIM cards in Japan. Complete the SIM unlock procedure before departure.
2. Understand Fair Usage Policies (FUP) & Speed Restrictions: Even plans advertised as "Unlimited" may limit speeds (e.g., max 250kbps if exceeding 10GB in 3 days or throttled during peak hours). If you stream heavy video content, consider fixed high-capacity plans like Ninja WiFi or CDJapan Rental.
3. Confirm Counter Locations & Hours: Counters generally operate from 7:00 AM to 10:00 PM. For late-night or early-morning arrivals, opt for 24/7 vending machines, hotel delivery, or advance eSIM purchases.
