Suggestions for unlocking Galaxy S3

Hello. So here is the problem.
I asked EE UK to provide me with a subsidy pin. After 2.5 months, they sent me a pin for I9300 SIII.
The problem is that my phone is SIII 9305, which is the LTE version. When I try to use it, the phone tells me that 'Network unlock request unsuccessful'
Since they used my IMEI number to request the unlocking code, why doesnt it work? Can anyone help please?

How to unlock network security of samsung a8(2018) sm-a530f ??

Hello,
My device bought from France. It was from a showroom. May be I cheated by them. I don't know about the carrier locked issue. My brother bought that for me and he confirmed me that this phone is not under any operator. It supposed to be factory unlocked. But after getting the phone I got this **** locked by carrier. Is there any solution for this ? If I install any custom rom then what will happen on the next ?? Help me in this field.
Thanks in advance.
