To complete the list, I want to share how you can also do similar thing on Glo. i.e. loan airtime from Glo and pay back later.
I initially thought Nigerians would be able to borrow and not pay back the borrowed airtime by dumping the sim, but I later realised that these telecommunication companies are smarter. The amount you can borrow is in proportion with your loading style.
Steps to Borrow Airtime/Credit from Glo
Dial *321# on your phone
Create a 4 digit pin of your choice
After creating the pin now use the following format to borrow airtime. *321*pin*amount you want to borrow#
Just like normal airtime, you can use this airtime for any thing.
Hint – Glo charges 5% of the total amount borrowed.
