Answered question
I'm trying to test the feature to unlock the data gifting badge and to get some extra points into my account, but I keep getting an error right after I choose the contact. I wonder if anyone else is experiencing the same issue.
I just tested and it works, but I sent it to a new contact, by entering his email. Did you try to gift data to a new or existing contact ? Also, your line has been active for how long ? It takes a while for all functions to activate in an account it seems.

Both accounts were activated last week and the number was already saved into my contact list. It seems like it was a temporary issue, it's working now.
