Unlock old postpaid Samsung phone


I'd like to unlock my old Samsung post-paid phone I got about 2013, and have had sitting in a drawer since I upgraded.  When I try the Optus unlock page and enter the IMEI I get an error message saying this is not a prepaid phone.  I know that Smiley Happy  How do I get an old post-paid phone unlocked?

Thanks Phil

Are you sure its locked Phil as postpaid devices have been sold unlocked for many years. Have you tried another carrier sim?

Thanks for your reply.  I tried a telstra sim and get a message selected network not available. In settings - about phone - status its shows the network as Yes Optus (which is why I thought it is locked to Optus).  Your reply made me check settings - wireless and networks - mobile networks - network operators which only show yes optus and vodaphone.  I guess its phone compatibility with the telstra network rather than being locked to Optus, and  I'll have to try a vodaphone sim to find out if it actually is locked?

What model Samsung is it and have you tried resetting the network settings or doing a full factory reset. Don't forget to back up anything important if you are going to do a factory reset.

I'd recommend a factory reset @DrPhil, it may also be a handset default itself. It would really depend on the model and age of the phone itself as well.
