Watched an NBA game the other night and they showed a scene of people

2. I'm going to a music concert where they put your phone in a locked bag until exit . You keep the

locked bag with you
and if you need to use your phone in an emergency there are stations set up outside the performance area where they can unlock your bag, or you get unlocked and return the bag at exit
They will have professional pics from the nights event online to upload
I understand the artist's request
You can always come without a phone to begin with!
