1. Buying a mobile phone by installment means that you use a credit card or other credit to pay by installment when buying a mobile phone. You don't need to pay the down payment or interest fee, you just need to return the installment principal every month until you pay it off.

2. Preventive measures

With the increasing popularity of credit cards, more and more cardholders choose the "zero interest" installment consumption model. Many people feel that the consumption burden is hanging, but "zero interest" is not "completely free". Interest-free installment payment of credit cards seems attractive, but in fact it hides "murder".

Take the popular car staging as an example. Although many banks or car dealers advertise "zero down payment, zero interest", the word "zero handling fee" is rarely used in advertisements. Financial experts revealed that credit card installment payment is essentially a disguised consumer loan. For example, the sum of the handling fees for installment payment can be regarded as the sum of the annual interest of consumer loans. It actually charges a certain fee.

3. Payment by installment

Installment payment is actually a loan provided by the seller to the buyer. The seller is the creditor and the buyer is the debtor. The buyer can get the goods or services he needs only by paying a small amount of money, but because the interest is included in the future installment, the amount paid for the same goods or services by installment is more than the amount paid in one lump sum.

On the one hand, installment payment allows sellers to complete promotional activities, on the other hand, it also provides convenience for buyers. Complement each other and take what you need.
