Why the insult to someone that wants to meet you in person ?
How rude of you !
Normal civilized people don't spent 4 to 5 zloty per minute on roaming phone calls when they can make the same call for 80% less using a international phone card Silly.
Maybe you could enlighten us on just how much a roaming call per minute would cost someone using their Australian mobile in Poland in real life delph ?
As civilized and wealthy as you are though it most likely would be no big deal for you to spend your weeks paycheck on an hour (six ten minute) of roaming calls.
if there are any phone providers that have cheap internationa rates
If you have a mobile that is unlock it may be to your advantage to buy a Polish sim card and switch it with the one you have in your phone now.
It would give you a local Polish phone number to avoid roaming charges on top of international charges.
That or buy a cheap burner cell phone when you get to Poland.
Doesn't Poland sell international phone cards that give you cheap rates or is that your original question ?
