Hi my friend used my code but he had to cancel but now he activated again but forgot to use my code. Is it possible to use the code still?
I don't think so, try contacting support via Live Chat to see if they can do something.
You cannot sorry
The texte from the guide
Pretty sure it’s too late.
You can't :(
The only moment you can use a referral code is when you activate your SIM card. After that, it is over unfortunately.
