Unlock 6600 Voda

[tryandc]

Hi,
I unlocked a 6600 from Vodafone with #1.
It now works with some O2 cards but not all of them.
Tried the other codes, most of them say something like "was not locked".

Model: Nokia (6600 )
IMEI: <removed>
Network: 23415000

Any idea what the problem is?
Thank you for your help.

Your phone is unlocked m8, are some of the SIM cards old, that could be the reason.
