How to Activate Your Japan SIM or eSIM
Requirements:
- Unlocked phone
- eSIM-compatible device (for eSIM)
- Valid email address (for online purchase)
Check Compatibility
Ensure your phone is unlocked and supports the required bands (most modern smartphones work). For eSIM, check if your device is eSIM-compatible.
Purchase Your Plan
Buy online or at the airport. For eSIM, you'll receive a QR code via email. For physical SIM, insert it into your phone.
Install eSIM (if applicable)
Go to Settings > Cellular/Mobile Data > Add Data Plan. Scan the QR code and follow on-screen instructions.
Configure APN (if needed)
Some providers require manual APN settings. Usually, it's automatic. If not, enter the APN provided in your confirmation.
Practical Tips
💡 Buy eSIM Before You Go
Save time and avoid queues at the airport by purchasing an eSIM online. Holafly offers instant delivery and easy activation.
💡 Keep Your Home SIM Active
With eSIM, you can keep your physical SIM for calls and texts. Perfect for receiving bank OTPs or staying reachable on your home number.
💡 Watch Out for Data Limits
Many 'unlimited' plans have a fair usage policy. Check the fine print to avoid throttling after a certain amount of data.
