Tip on Making International Calls for Local Charges
All Free Calls is a telephone service that recently popped up, out of Iowa. Here’s the shtick: you can make phone calls to many foreign countries (more than 30) for the cost of a local call to Iowa. Techcrunch did its darndest to figure out and explain exactly the mechanics behind how the system works. Suffice it to say, it works. Here’s how:
1. Dial - Dial 712-858-8094.
2. Listen - Listen to the instructions in Mandarin, Spanish, or English.
3. Talk - At the prompt, enter 011, the country code you are calling and the number you wish to call. Enjoy your free call! There are no hidden charges, and no sign-ups, no limit on call length or number of calls, and privacy is guaranteed.

Calling cards are available to call Moscow for as little as $0.017 / minute - likely far less than a domestic long distance call to Iowa.
Most of the calling cards have an added usage fee per call, or some other hidden costs, so the actual cost is rarely what advertised, at least in my experience. i call eastern europe too frequently and 1.7 cents/min seems a little low, i am dealing mostly in the 6-8cents /min. If have additional insight please post
I wouldn't count on these types of services lasting!
