I have a contract with AT&T but am leaving the country for 2 months.. Can I suspend the account?

I have the iPhone with a 2 year contract and I'll be in Poland this summer for two months.. I dont exactly want to pay for a phone I won't be using. What can I do? Thanks!|||you can put it on hold and pay like 10$ a month or cancel it and pay like 200$ for violating a contract
