Play network in Rzeszów

Hi! I am an American student traveling for the first time to Poland. I want to buy a Polish SIM card for data usage in Rzeszów only, and I have a few questions:

(1) How is the data reception for the Play network in Rzeszów?
(2) Where can I buy Polish SIM cards in the United States?

Thanks in advance for any answers!

1) Play is fine in Rzeszwów, it's a city so they're mobile antennae all over the place
2) Probably can't but you can buy SIMs at any wee kiosk all over Poland, can't see much point in selling them in 'Merika.

Thanks. You're the best!

damn straight ;)
