Can an International student staying 2 yrs in Poland, take out 2 yr cell phone contract?

I'm gonna be staying for 2 years in Poland and was wondering if I can sign a 2 year contract and buy a phone with some carrier, t mobile, orange etc?

I think you'll need to be living in Poland for 3 months before you can get a contract, you'll need a permanent address too.

But call into one of the shops and ask, I'm not sure if all of them adhere to the 3 month thing.

Get pre-paid. It isn't expensive in PL and if you pay (I think) 125zl you get 5gb of data from Play.

Thanks, I was mainly interested in getting the phone cheaper by being on some contract but we shall see until September.
