Hi Misoko! Can I ask you a question about cellphones?
Sure! I'm using SoftBank now. What do you want to ask?

I'm currently on docomo now, but my contract is ending and I was thinking of switching to a different carrier. The problem is my smartphone is currently SIM locked to docomo. Do you have any idea what to do? Do I need to SIM unlock it to work on another carrier?
You will need to SIM unlock your smartphone before signing a new contract. Don't worry though!  I will help you unlock your smartphone!

Unlocking a docomo smartphone

1. Conditions for unlocking a smartphone

① Currently under a docomo contract

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

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

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