i have got a email for unlocking my iphone

[John]

it says that "contiune by putting in a non o2 sim and connect to itunes and itunes will tell you that your phone is unlocked, 

I have done that all and my phone has been connected to i tunes for 20 minutes now but still it is not unlocked.

IPhone 6

You don't need to connect to iTunes.  Simply put a non-O2 sim in the phone.

What iOS version are you on?
All you need to do is put a non O2 sim in as it's unlocked on Apples servers, there's no need to connect to iTunes if on latest firmware.

Hi @John

For iPhones you will not receive a code. Just replace the O2 sim with one from a different network once you receive notification that it is unlocked.

If the unlock fails first time, try connecting to iTunes to complete the process, but this is not required for every phone.

I have done that on the top it still says "no service"

[John]

So how long will i have to wait for then?  

i am on ios 11.4.1

It's instant but sounds like the unlock has failed or Apple haven't updated their servers yet.
Try it again tomorrow and if no good, request unlock again.

[MI5]

No, same process for all iPhones.
