SIM network unlock PIN

Hiya,

 

I've recently bought a new SIM card with a better contract than the one I was on before, however I'm having trouble unlocking my Sony Xperia Z3 from O2. I've tried speaking to the people at O2 and when they couldn't do it they recommended I go CEX which I have. They sent away for a code but it came back saying there were no codes available. 

 

I'm not sure whether this is linked or not but I saw a thread advising people to call *#*#7378423#*#* which I've done and I've brought up the SIM lock screen. At the moment, mine reads:

 

[x] network 5
[]network subset 0
[]service provider 0
[]corporate 0
[]sim 0

 

Could someone please tell me what network 5 means and how I now go about unlocking my phone.

 

Thanks in advance

In other words, the phone is locked to O2 and they told you to contact someone else to get the unlock code?

Yeah, I went into the O2 shop and they asked a few questions. Because I didn't buy it directly from O2, they couldn't unlock it so asked me to get a third party to unlock it instead.

Re: SIM network unlock PIN

What terrible customer service from 02,

i can't see the difference, you were using their service and making them money.

Regardless where the phone was bought. 

I can't see why they cant unlock it,

it should be able to be done over the phone. 

I think they're just been difficult.
