Installment crdit lines are a way to make repaying larger credit limits easier for some Fido customers. Customers eligible for installment credit lines will have this option in the app to choose multiple payments, instead of 1 payment that is due in a month.
Fido offers up to 6 months of installment options. This means that instead of repaying the entire credit facility after the usual one-month period, Fido will divide your credit repayments into small equal amounts. Hence, you pay a small part of the credit each month over the installment period (1 to 6 months) you have chosen.
Note that, it does not mean you will repay the entire credit amount after the period you choose, but it means each month you will pay a part of the bigger credit amount that was received.
