Unlocking Samsung SM-B550H

I have a Samsung SM-B550H locked to O2. I requested an unlocking code from O2 and entered it into the phone so I can use other sim cards. The phone is still unable to work on other sim cards apart from the O2 card. I have no error message. I called Samsung for help and spent nearly 1 hour on chat and Samsung could not help and asked me to speak to O2. Can anyone help how I can unlock the phone? Do I need a defreeze code or any other code? And do I need to request unlocking code again if I have entered it too many times.

It sounds like it's hard locked now and you will need a MCK code

@Martin-O2  @LukasB any help you can offer?

@Solky55 

If it's hardlocked due to too many incorrect attempts you need @Martin-O2 @LukasB or @TheresaV to get an MCK code for you.

Check the process to ensure you have requested the correct code though Guide: Unlocking an O2 phone to use a different SIM card

LikasB & M15 for the quick response. How safe am I to provide my personal information requested? Nowadays one has to be very careful. Please do not take it wrong, just making sure.

Thanks for understanding.

@Solky55 

You're welcome and although @LukasB looks a bit dodgy, he's not at all thumbsup
