Very often you come across tricks to make free calls and honestly, most of them don't work. I recently came across a trick that really works so it gets to feature on my blog. So here goes the trick to make free STD and ISD calls with Skype.
What we are going to use in this trick is a service called Free411. Its actually a US based service with the toll free number- +1-800-FREE411 which is +1-800-3733411. Skype does not charge for calls made on toll free numbers so calling this number using Skype won't cost a penny. So here's what you have to do-
Dial +18003733411 on Skype and click on the call button to connect the call. I would suggest you to save this number in your Skype contacts for faster future access.
The call will be answered by an IVRS system. You will have to bear a small ad before you reach the main menu. When prompted to select your option, say "Free Call". Now if their lines are not busy, you will get a 5 minute free call. You will be asked to dial the phone number to which you wish to make the call. Dial the full number including ISD code. For example prefix Indian mobile numbers with +91, UK numbers with +44 UAE numbers with +971 etc.
This service works well for me and usually I manage to connect to a free call within 5 to 10 minutes of trying to get a free line which is acceptable considering that this service is being used extensively in the US and also by people from all parts of the world. Leave a comment if you face any kind of difficulty or have any doubt about this service.
PS-The service I've mentioned here is a free service. Please use it judiciously and don't use it for making prank calls. Your idea of fun will might make this service unavailable for someone who needs it more than you do.
PPS-For all my friends who for some reason haven't added me on Skype yet and for those who intend to create a skype ID after reading this post, my ID is namanbagga.
