I am not paying for my cellphone, I see everyone is on WhatsApp already and I call them on WhatsApp. That said I live in India. I already pay for fiber gigabit connection at home, so spending extra on mobile is not worth it for me. That said, most of job is done on email/WhatsApp and I rarely need to call anyone. And if need comes, I'll just recharge my mobile through internet and get it going within 5 minutes.
