Hey AirtelTrickianz, I am damn sure, you all are quite excited after reading header of this post. Yes, now its very much possible to call unlimited in any country without any issue of call drop cause it does not require any Internet connection. Isn't it cool ?
Let's see How ???
Steps to Follow :
1. Go to knowlarity.com
2. Click " Try Free For Life " and signup with any random name and any disposable mail id like yopmail/10minutesmail.
3. Now enter your real mobile number.
4. Verify email.
5. Now check your mobile, you will get a sms saying you have to give miss call to a given number, go for it.
6. Now you can see your account dashboard, just click on " click to call ".
7. Choose serial no, user and at last put the number you want to call.
8. Finally you will get call just receive it and you both will get connected.
Only sad part is, You cannot call DND registered number :(
You will get 20 coins for sign up worth 10 minute of calling but do not disconnect call after 10 minutes, just keep talking hours or even 10 hours. It will not get disconnect automatically
Best part is you don't need to provide different new numbers, you just provide same number ( but different mail id ) and repeat the process for unlimited calls.
