Whether you need to change your phone when studying in Japan in 2025 depends on several factors. Here's a breakdown in English:
Do You Need to Change Your Phone for Studying in Japan?
- Network Compatibility
Japanese mobile networks (4G/LTE and 5G) primarily use 频段 (frequency bands) such as:
- 4G/LTE: Bands 1, 3, 11, 19, 21
- 5G: n1, n3, n28, n41, n78, n79
Check if your current phone supports these bands. Most modern Chinese smartphones (e.g., Huawei, Xiaomi, iPhone) have global 频段 support, but budget models or older devices might lack Japanese-specific bands.
- Carrier Lock
If your phone is locked to a Chinese carrier (e.g., China Mobile, Unicom), it may not work with Japanese SIM cards. You’ll need to unlock it first (contact your carrier) or buy an unlocked device.
- Local Services & Features
- Mobile Payments: Japan’s Suica/PASMO mobile IC cards require phones with FeliCa technology (common in Japanese models like Sony Xperia or domestic brands). Most Chinese phones lack this, so you’ll need a physical IC card or use cash/apps like Apple Pay/Google Pay instead.
- Emergency Calls: All phones can dial 119/110, but some features (e.g., location sharing with local carriers) may require a Japanese device.
- Language & Settings
Phones support multiple languages (including Japanese/English), so no need to change for this reason. Just adjust settings in Settings > System > Language.
Conclusion
- No Need to Change If:
Your phone is unlocked, supports Japanese 4G/5G bands (check specs on your manufacturer’s website), and you don’t mind using physical IC cards for transit payments.
- Consider Changing If:
Your phone is old/band-incompatible, carrier-locked, or you want full access to Japanese mobile features (e.g., FeliCa). You can also buy a cheap local second-hand phone in Japan.
English Version for Reference
Whether you need to switch phones when studying in Japan in 2025 depends on your device’s compatibility with Japanese networks and services:
- Network Bands: Ensure your phone supports Japanese 4G (Bands 1, 3, 11, 19, 21) and 5G (n1, n3, n28, n78, etc.). Most modern Chinese phones work, but confirm via your manufacturer’s specs.
- Carrier Unlock: If your phone is locked to a Chinese carrier, unlock it first to use Japanese SIM cards.
- Local Features: Phones without FeliCa can’t use Suica/PASMO mobile payments, so you’ll need a physical card instead.
- Recommendation: Keep your phone if it’s unlocked and band-compatible. If not, consider unlocking it, buying a local device, or using a temporary phone for essential services.
