My previous job required having a Postpaid Airtel line, it was compulsory.
At first, I thought it was ridiculous and that it would only make me spend more money on calls as I am no longer restricted to the value of my last recharge voucher.
Now in my second year of using a postpaid line, I can boldly say its benefits are enormous. I no longer hunt for recharge cards, I get a detailed record of my monthly calls and SMS, I get to pay anytime (nearly so) and extremely cheap call (and SMS) rates. But the best part is my calls don't get unexpectedly terminated.
In fact, my BIS runs on my postpaid line so it never expires. And with Airtel's unrestricted 1GB data bundle that comes with the NGN1,400 BB complete pack, I have permanently solved my data needs.
I hope I have been able to convince you and not confuse you that having a postpaid line is extremely cool, cooler than a prepaid line. Thank you!
