2. Login to your yahoo messenger with your yahoo id and password.
3. If you dont have an account with yahoo, go and get one.

Making PC to Mobile Phone Calls Free:
1. Download and install the latest version of Yahoo Messenger
(Yahoo Messenger 10 final)
2. Login to Yahoo Messenger and configure microphone and headphone settings.
3. Dial 18003733411 in the search box available in yahoo and dial.
4. A new window will pop up with the call details.
5. Now you will be connected to an IVR system and select the option FREECALL, which probably is the last option in the IVR menu.
6. Now Say, “FREE CALL” clearly and loudly, such that the voice recognition system takes your command and directs you to next step.
7. Now wait for few mins till the advertisement completes.
8. You will be asked to enter the Phone number with ISD CODE, STD CODE and the NUMBER. In case of Mobile Numbers, Country code + Phone number is sufficient. (Eg: For a mobile number in India you have to type 91 99624 12345 where as a mobile number in USA is 1 234567890 where 91 and 1 are ISD codes of respective countries.)
9. You are done. Your call get connected and you can talk nonstop for 7 mins before the call get disconnected. If you want to talk again, you can call again. 
Note: This trick is possible because the number 18003733411 is a free toll free number which allows you to call free calls at the expense of an advertisement. This is the best UNLIMITED CALLING TRICK that is available.
Your trick did not work. Repeatedly it is indicated to subscribe to Yahoo Voice which costs. Can you please elaborate and help.
Thanking you.
