How to unlock Xperia 1 from Xperia 1

　"Xperia 1 (SO-03L)" purchased as a model change in DOCOMO.The first thing to do after obtaining is "Unlock SIM".This time, I purchased it by splitting using the "Smartphone Hosting Program", but since it has been more than 100 days since I unlocked the previous terminal, it can be unlocked immediately after purchase.

　Furthermore, if you did not access "My docomo" with a PC browser, you could not access the SIM unlocking item, but now you can access it from your smartphone web browser.

　So first access My docomo from the Xperia web browser.Tap "Contract content / procedure" and scroll down the screen to the "SIM unlock".

Access "Contract content / procedure" with My docomo and tap "SIM unlock"

　Furthermore, tap "Procedure" from the menu and move to the procedure screen.To release the SIM lock, it is necessary to enter the serial number (IMEI), so check in advance.The confirmation method is displayed when you enter the dial "*#06#" from the call application.

Tap "Procedure"

Enter various items for unlocking SIM

IMEI can be confirmed from the call app

　All you have to do is follow the explanation.When the SIM unlocking application is completed, the "SIM Lock Code" will be displayed, so write down.The SIM unlock code will also be sent to the docomo email address.

Write down the "SIM lock unlock code" on the application completion page

　Finally, remove the docomo SIM stuck in Xperia 1, set the SIM other than docomo and restart it.Then, the page "Lock Pin of SIM Network" is started, so enter the SIM unlock code mentioned earlier.

Insert it into a SIM other than docomo

Enter the SIM lock unlock code

　If the SIM unlock code can be entered without any problem, the work is completed.Now you can go abroad and use local prepaid SIMs in Xperia 1.It is quite easy to unlock the SIM with just a smartphone.Moreover, if you do it yourself, the cancellation fee is free, so if you are using the SIM unlocking conditions, release it so that you can go abroad anytime!
