Hello, Could you please help me, I have purchased unlocked Samsung J6+ in Serbia, and sent it to Australia to a friend. Now she is not able to activate SIM cards. The device is working perfectly without SIMs, but with them in it, the device is showing this info: "SIM network unlock PIN: ____" offering two buttons: unlock and dismiss. Can we somehow unblock it from Australia, or she should return the device to Serbia for unblocking? Thanks in advance for answer and help.
