Using an Airtel SIM, you can easily borrow credit by dialing the USSD code *500*amount# on your mobile device. The only pitfall here is that you can only borrow up to N500.
Most people have complained that borrowing airtime is a way by which these network providers extort money from Nigerians but one cannot deny the fact that these innovation has saved a lot if people time and have been used in emergency cases.
The only disadvantage of this USSD code service is the service charge been deducted on the network you’re using. This service charge normally ranges between 10 to 15% depending on your choice of network.
Hope you can now borrow airtime from MTN, 9mobile, Glo & Airtel using these codes easily now.
