I am trying to unlock Oppo A73 to use it overseas with another network provider. Currently pthe hone is locked to Optus network.
I already have unlock code sent by Optus. I am trying to enter *#789# on dial pad to enter unlock interface but it's not working.
How can I enter unlock interface now?
Just trying to understand once you enter *#789#, does the supplied network unlock code not work or you are not prompted to enter the code in the first place?
If it's the latter, you may need to contact Oppo.
