I been told by the O2 Ireland customer service that my phone  will having difficulty for unlocking due to undefined registration of the handset which made me upset.

I tried the service of MobileUnlockCode.Co.UK and after waiting for the unlocking code for  10 working days, my Samsung Galaxy Fame GT-S6810P locked to O2 Ireland has now successfully unlocked. Thank you MobileUnlockCode.Co.UK! 

I'm still waiting for my unlock code after 5 days.  They don't answer the phone and their voicemail is full.  Not a good sign for getting my moneys worth.   No email response either.

Don't touch mobileunlockcodes.co.uk/unlockingonline.com is my review. An expensive lesson for going with the cheapest rate.
