Choose the mobile phone you want to buy on Taobao, Tmall, JD.COM and other e-commerce platforms, and choose the installment payment option at the time of settlement. These platforms usually support credit card installment (for example, flower installment and JD.COM installment) and consumer loan installment (for example, installment music). After selecting installment payment, you need to confirm the order information, including the installment payment period (such as 3, 6 or 12), and submit the order.

2, through the mobile phone brand official website or official flagship store to buy. Choose your favorite mobile phone model in official website or the official flagship store of the mobile phone brand, and then choose installment payment as the payment method. Apple official website, for example, supports credit cards to buy mobile phones in installments.

3. Pay in installments through physical stores. If you choose to buy a mobile phone by stages in a physical store, you need to bring your ID card, bank card (the overdraft limit of the credit card must be greater than the price of the mobile phone) and other necessary documents and materials. In some cases, if you have a social security card or driver's license, it can also be used as proof of identity.
