prepaid card option as Tourist

AT&T does not ship outside the United states. You may be able to purchase a prepaid sim on Amazon, as well as prepaid refill cards. But you should not activate the service until you arrive in the United States.  Esim can only be activated and set up in the country of use

Is there an AT&T booth at the Las Vegas, NV airport where I can get a card right after landing?

If so would it just be physical cards or are there eSim available as well?

@nrenken81 if you are going to use an e Sim you can do so as soon as you are in the United states. You do not need to go to a store as long as you have a compatible phone

@nrenken81 Note that ATT has a strict list of compatible phone models, so without knowing your phone we can't answer whether you can even signup for service.

https://www.att.com/idpassets/images/support/pdf/Devices-Working-on-ATT-Network.pdf is the latest available list from last November.

Hi, I own an Google Pixel 7 Pro 

@nrenken81 If you have the International model, it isn't listed on ATT's PDF I provided a link to.  So there is no guarantee that ATT will accept it.
