Hey there
I’d be happy to help with your travel to NYC and keeping you connected! You can certainly use our GoPhone service to gain access to talk, text and data! To do so, please ensure the devices you will be using are unlocked for use on our network. You can then purchase a GoPhone SIM and any refill cards needed at our AT&T company stores or authorized retailers! To find the nearest store to where you will be staying, check out our store locator!
Unfortunately if you are currently outside the US, we are unable to ship refill cards/GoPhone SIM kits internationally. I apologize for any inconvenience this may cause.
I hope this helps!
