I prefer postpaid as I don't need to worry about the costs while talking and can use it withcomfortability. I did try pre-paids but the very fact that my amount is getting deducted every second just doesn't let me use it at ease.
Secondly, on Zero Rental Scheme I get to talk what I pay for, contrary to almost half of the amount paid deducted as taxes and others in pre-paid vouchers( I am not aware of the current scenario).
Last but not the least, my postpaid bill is received by my dad while I would have to spend my own pocket money for vouchers
