Can't use SIM card on BlackBerry 8320

[octavia77]

I can't use my sim card on BlackBerry 8320, It seems like they do not support my network T-mobile(Croatia).
I bought this phone as unlock, and when I opened SIM and tape mepd i got:
Sim: Disabled
Network: Disabled
Network Subset Disabled
Service Provider: Disabled
Coporate: Disabled
I try to tape: mep2 nothing hapened
I try to tape: MEPE- nothing hapened.
So I think that my phone is unlocked but not suport my network.
But you can use this phones BB 8300 BB8310 BB8520
So can I download some part of software from this models, to use on my BB8320.

mep2 is network lock already disabled, sounds dumb but have you enabled a network connection?

OK, the phone is definetly unlocked.
It will definetly read 1 mobil network (tele2) becouse that network can bee found in networks, and I can call SOS from that network,
but it won't read t-mobile(Croatia).
Can I make it someway to read my network t-mobile.
