Many people have been now successfully using Tuitalk for making free calls to India (I am one among them), however some are not able to Tuitalk even after trying various tricks.
For people of UAE, it might be possible that Tuitalk is blocked by your ISP. Our regular reader Mr. VijayKumar also pointed it out and told us about running Hotspotshield.
Its simply provides a VPN network (Virtual Private network), basically kind of coming between your ISP and the voip software (in this case). You will be assigned a USA IP address and your ISP will not be able to block those voip softwares (Tuitalk, nonoh, etc).
Just follow these simple steps.
1. Download Hotspot Shield.
2. Run Hotspot shield (the one you downloaded).
3. It will auto search and connect.
I hope after Running Hotspot shield you will be able to make free calls using Tuitalk.
Again I do not guarantee that this method will unblock all your voip providers (Tuitalk etc) to make free calls and I know many people have already got frustrated trying Tuitalk, but hey just give one more try to this one. (If it works, then you will be able to make unlimited free calls).
After all you can stop using Hotspot Shield at any point of time and uninstall it.
Do let us know if you are successful in making free calls.
