Where can I get a prepaid Phone to use internationally?

There is a phone store in the Kiev International terminal that you can use to buy a phone. If you are looking for something just to use to make calls and send text messages with it should cost no more than $50 or about 400 Ukrainian Grievas. Once you buy the phone buy a sim card. To use for international calls go with LIFE. They arre the cheapesst to make international calls with. 1 minute of international time will cost 1 ukrainian grieva (about 12.5 cents in USD)
