Unlocking a SoftBank smartphone

1. Conditions for unlocking a smartphone

① Currently under a SoftBank contract

  • Complete the process through My SoftBank (Free)
  • Complete the process at a SoftBank Shop (3,000 JPY)

Complete the process through either of the above. It is recommended that you complete the process online through My SoftBank since it is free.

② If you are not under a contract (canceled contract, bought the phone used, someone gave it to you, etc.)

  • Complete the process at a SoftBank Shop(3,000 JPY)ONLY

If you purchased your phone from someone other than the SoftBank shop, it is not possible to unlock your smartphone on My SoftBank online.
In addition, 101 days or more need to have passed since the product was purchased and paid in full. If you do not know the purchase date of your phone or purchase method, you can check this information at a SoftBank shop.

 

2. Using the My SoftBank Unlock Method (Online)

Now that we have checked that we are able to unlock the phone, it is time to get to what you have been waiting for...unlocking your phone!

Follow the instructions below to get the IMEI and go through the online SoftBank website to unlock a smartphone.

 

① Get the IMEI (serial number) and make a note of it (This will be necessary later on!)

  • For iPhone/iPad

*You may receive the message “SIM unlock is not finished yet” [SIMロック解除はまだ完了しておりません], but rest assured that the SIM unlock procedure should be completed.
