I would like to check if my device SIM is unlocked (iPhone)

You can check if your device is unlocked or not by operating the device.

Please see below for detailed steps.

Important note

If you are using iOS version before 14.4, you will not be able to verify using the following steps, so please make sure to update your iOS before checking.

How to check if my device SIM is unlocked

After registering for SIM unlock on My au (Web) or at a shop and inserting a different carrier's SIM card, you can check whether the SIM unlock has been successfully done with the method below.

Steps to verify SIM unlocking

Tap on "Settings" [設定].
Tap on "General" [一般].
Tap on "About" [情報].
If the "SIM lock" [SIMロック] column displays "No SIM lock" [SIMロックなし] , the SIM has been unlocked.

Simply completing the SIM lock removal procedure will not change the status from "SIM locked" [SIMロックあり] to "No SIM lock" [SIMロックなし].

You need to insert another company's SIM card and perform activation to display "No SIM lock" [SIMロックなし]
