Airtel has a service called Call Collect that ensures that the person receiving the call pays for the call instead of you so you don’t get to spend a dime at all when making calls.
This is quite similar to calling a number without having airtime on Airtel but it is quite better. This is for the fact that you will not pay for the call at the end of the day.
Since it is an official plan from the telco, it also means that the person receiving and eventually paying for the call would be notified before he or she proceeds with the call. So, giving the individual the option to either decline the call or accept it with no harm done. Now that we know these things about the Airtel Call Collect service, we can now proceed on how to make someone pay for your call on the Airtel network.
How to make someone pay for your call on Airtel
Pick up your Airtel SIM card with or without data and dial # followed by the number that you want to call. E.g #080123456789 and dial. Please note that this Airtel call collect service only works for Airtel-to-Airtel SIMS and not to any other network operator.
