Update: Currently the service for free calls has been removed so the information in this post might not be entirely accurate. You might want to check this post on how to make free calls from your computer to any mobile phone.
Everyone must have heard of free calls between computers using softwares like Yahoo! Messenger, Skype and Google Talk. Now-a-days calls from mobile-to-computer using GPRS is also common using mobile applications like Fring, Nimbuzz, etc. This is a simple trick to make calls from computer to almost any mobile or landline phone to many countries. All you need is Yahoo! Messenger or Skype or any other calling application which allows paid calling, internet connection with fair speed, speakers and microphone. 
How to make the free call?
The free call is provided by Free411. I will guide you through Yahoo! Messenger.
-
Enter the number 1800-FREE-411 (1800-3733-411) where you enter the call number and make the call. This is a toll-free number.
-
Wait for the call to connect. Once it connects, follow the voice instructions to reach the ‘Main Menu’. Say “Free Call” once Main Menu reaches.
-
Once the system says ‘Dial the number’, dial the number using the dialpad in the international format.
Example, to make call to India, dial 91 followed by a landline or 10 digit mobile number like 919876543210.
That’s it! Your call will be connected… The call limitation is 5 minutes. But you can call again countless number of times!! Sometimes a 20 sec long ad will be played when the call gets connected. Just listen to what the IVR (Interactive Voice Recording) says and follow the instructions.
At times, the system remains busy.In such case, call again, and it will work 
The procedure is same for Skype too.
This is tested and works in India. Try for different countries and enjoy free calling… 
Great man. Free calls awesome.
i told ‘free call’ many times…but it is not saying to dial the number
@ Dinesh
Thanks buddy… Try for different countries and post it here…
The same procedure can be followed by Skype users to make free calls using Skype as calls to US toll free numbers are allowed using Skype too!

Just tried, but it says – To make this call, you need to sign up for Phone Out. Rates as low as 1c/min, what dose that mean?

There must be some mistake. I tried with older and newer versions and found no error. It might be the problem with the number you are dialing. Please retry and post it here.

I tried it 13 times…and it still says “all line are busy”
is there a problem with my messenger?

@Ajit
Sorry for late reply friend, if you are getting no balance error, there must be the problem with the number you are dialling, as the number 18003733411 is a toll free number. You will not be charged for the call.
@Wwekid @Tej
Friend, the system remains busy at times, don’t lose heart, keep trying…

Guys, sorry for late reply. It seems like this service has been withdrawn by the provider.
Hi!
I’ve been trying this idea to call internationally for long now – but the operator never gives the option of Free Call. All she says is – “Choose your category: Business; Government; Residential; Horoscope….” but NEVER Free Call. Tried hard several times in sub-options too but no luck! Phew!
Please guide us again. Thank you!
BTW – I live in India .
It would be highly appreciated if somebody could provide a step by step procedure to make international calls especially since the menu options have been definitely changed.
Thanking you….
I guess its odd to reply too late and say sorry. But whatever be the case, the service of free calls have been withdrawn
. No alternate methods for international free calls are discovered yet. And do a search at DW on free calls. I guess there is a post for it. Thanks
it doesnt work.
it doesnt say free call in main menu
what to do plz help me
oh there is one site http://evaphone.com just type that end and make a phone call. it automatics pops up as a phone. u will see
This is just fake . I have tried it many times but it is not free.

I am unable to make it
Unable to make call.The recorder never gives the option of Free Call. All says is – “Choose your category: Business; Government; Residential; Horoscope….” but NEVER Free Call. Tried hard several times in sub-options too but no luck! Phew!
Please guide us again. Thank you!
