6230i unlock

Hi,

I'd like you to help to unlock my 6230i phone:
IMEI: 3570xxxx (edit: IMEI removed)
Network: Pannon GSM, Hungary

I have used free unlock code generators, and tried the 2 codes below already:
#pw+804161540505700+7#
#pw+880221321126767+1#

Other networks's SIM was in the phone, entered whole code at "Undo" prompt
However, none of the two codes have unlocked the phone, "Incorrect code" (or similar, it said in Hungarian)

Any ideas what to try? Thanks for your help

 

You had only 3 attempts.
#pw+827 021 540 505 700+7#

 

And this worked. I'm truly impressed. Thank you very much

 

Thanks for the reply.
