You have docomo right? Is your phone bill high?

Unlocking an au smartphone

1. Conditions for unlocking a smartphone

① Currently under an au contract

  • Complete the process through My au (Free)
  • Complete the process at an au Shop (3,000 JPY)

Complete the process through either of the above. It is recommended that you complete the process online through My au 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 an au Shop(3,000 JPY)ONLY

If you purchased your phone from someone other than the au shop, it is not possible to unlock your smartphone on My au 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 an au shop.
