Hello! I am going to be moving from the US to Krakow, Poland in a few months and was wondering if there was any suggestions on how to use my iPhone on either a regular sim or prepaid sim while there?

I am currently using a US T-Mobile Sim on an unlocked 1.1.4 iPhone.

Any help would be awesome.

Thanks!

Your question is in wrong topic, that's why nobody replied.
You can freely go to Krakow and stick any sort of sim card inside
