Practical guide
Choose roaming, a local SIM or portable Wi-Fi
Roaming is simplest, short-term local SIMs suit heavier data use, and portable Wi-Fi can work well for groups. Check band, dual-SIM and eSIM compatibility before buying.
- Compare your home carrier's roaming pass
- Consider a local SIM for longer or data-heavy stays
- Use portable Wi-Fi for several devices
- Keep your original SIM active for verification texts and disable expensive data roaming on it
Local SIMs require real-name registration
Foreign visitors normally take their passport to an operator shop or designated service point for identity checks, plan selection and activation.
- Bring the original passport
- Confirm validity, data allowance and overage rules
- Test calls, SMS and data before leaving
- Record support and renewal details
