1. Eligibility
The device has been activated on SoftBank for at least 101 days; no unpaid bills; installment devices must be fully paid; not reported lost or blocked.
2. Account setup
There are two ways to run an unlock. Own account: add your My SoftBank account under Account — not limited by the system. Default account: uses the shared system account, with a daily limit based on your plan.
3. Steps
Open the SoftBank international unlock page, paste the IMEIs (one per line) and press Unlock. The system logs in to My SoftBank and sends the request. The result includes the unlock code if successful.
4. Common errors
Not eligible: under 101 days or unpaid bills. Not found: the IMEI does not belong to SoftBank. Wrong login details: the My SoftBank account was entered incorrectly or its password was changed.
