Purchase checklist
This guide covers one prepaid, data-only option. It does not report hands-on speed or coverage testing and does not promise unlimited high-speed data.
| No. | Check | What to verify |
|---|---|---|
| 1 | Phone support | Confirm that your phone supports eSIM and is SIM-unlocked before paying. |
| 2 | Data only | The plan does not provide a phone number for cellular calls or SMS. |
| 3 | Plan duration | Choose the data allowance and active period shown for the Japan plan at checkout. |
| 4 | QR deadline | The Japan purchase flow states a 30-day QR-code validity period. Install it before that deadline. |
| 5 | Refund window | A refund may be requested within one week only while the QR code is unused. It is unavailable after use or from day eight. |
| 6 | Checkout conditions | Payment and identity-verification requirements can vary. Check the current purchase screen before paying. |
