I do not own a cell phone and have attended many Ticketmaster events in recent years. If you explain you do not have a compatible device, and sometimes use the word discrimination, they will take a credit card by phone and have paper tickets waiting for you at the box office. It annoys them, but not my problem. Prepaid credit cards are recommended for privacy.
I have not installed the TM app - you can add a ticket to Apple Wallet from the website, and every order I've seen has "don't have a phone? go to the box office for tickets when you arrive" somewhere
They're not allowing that in general any longer. I wasn't allowed to log in to their site this summer without phone text verification.
However, I believe they still have a ticket printer for emergencies, such as when you show up at the window saying you broke your phone, but just happened to print a receipt before leaving.
I want to: USE THE TICKETMASTER™ APP FOR MY TICKET, AND NOT HAVE ANY OTHER WAY TO HAVE IT—DEFINITELY NOT PDF.
So that: I CAN HAVE THE CONCERT EXPERIENCE OF THE FUTURE©
