Try voip discount. They offer 300 minutes/week of free calls to landlines and mobile phones in the U.S. You only have to pay a small connection fee (like .05 cent American dollars) for a call, and after you use your free 300 per week, then you pay .015 c/m. Go to voipdiscount.com. They have a system like Skype where you download a program, but the voice quality and stability of connection is better than Skype, if you ask me. Also, if people from the states want to call you in Poland using voip discount, it's the same free 300 m/wk. with more than that costing .015 c/m plan for them to call your landline, and .07 cents /m for a mobile phone. My boyfriend lives in Poland and I've spent a lot of time scouring the internet for the best deal for both of us-this is by far the best I've found. Hope it helps!
