This is quite simple, all you have to do is get or download
'Super Bluetooth Hack' at google download links. After you've downloaded & installed it on your phone. Get another bluetooth enabled phone, connect the two mobiles together through bluetooth on the app. Select "CALL" on the options menu
and select "DIAL NUMBER', then input the number u wanna call and ok. Your own airtime won't be deducted, it is the airtime
on other phone that will be deducted.
