To keep track of your airtime purchases:
1. Login onto the Euphoria Telephone Management System
2. Click on the Billing & Accounts tab on the left-hand side of your screen
4. Click on Voucher History tab
The voucher history is a list of all the airtime purchases since the inception of your account. This is a good way to keep track of how often you are adding airtime, as well as a good indicator of your airtime usage.
