i purchased an oppo a73 outright around six months on a pre pay.
i now want to unlock my phone, and when i go through the optus online form it says my phone is already unlocked however it doesn't work with any other sim card.
thanks in advance
Hey peejadams - that is definitely odd, please send us a private message, confirming your IMEI number. We provide you a network unlock code to see if that helps.
