A month ago, the New York Times published an article named “Free Services to Inspire Your Cellphone,” and in it there are 2 absolutely free services that I find pretty jaw-dropping.

1. Free Directory Assistance, dialing 1-800-FREE-411 (does have an ad you have to listen to though). Or, text message 46645 (G-O-O-G-L) with what you need(in terms of directories, or even weather, stock quotes, definitions, directions, etc) in the body of the message. The third option you have is to call 1-800-555-TELL where an automated voice asked you what you need.
2. Free International Calls - call FuturePhone at their 1-712-858-8883 access number and follow directions. It is totally free, and it includes over 50 countries, not always mobile phones. Note: I did try this twice, and found that all ‘circuits were busy’, so it may not be as easy to use as it looks…
