Use the Airtime Topup option to add airtime minutes to your mobile phone or to the phone of another user. Purchase airtime minutes using your primary payment instrument. You can see all airtime top-up transactions in the View Transactions and Bill History search results.
To add airtime minutes, select the invoice type (Operator) and enter the amount. If you are adding airtime minutes to the phone of another user, enter that user’s mobile phone number. If you do not enter a mobile phone number, then you are adding airtime minutes to your own mobile phone.
