Installment credits are a way to make repaying larger credits easier for some Fido customers. Customers who are eligible for installment credits will have the option in the app to choose multiple payments instead of 1 payment that is due in a month.
Fido offers up to 3 months installment options. This means that instead of repaying the full credit after the usual one month period, Fido will divide your credit repayment into small, equal amounts, so you pay a small part of the credit each month over the installment period you have chosen.
Note that it does not mean you will only repay the credit after the period you choose, but it means each month you will pay a part of the bigger credit.
