1. You need the business hall you bought to support the credit card you have. If you don't support it, you can't generally handle it. For example, the business hall only supports ICBC credit card, and yours is CCB credit card, so it is impossible to handle it.
2. The credit limit in your credit card needs to be sufficient, and it needs to be greater than or equal to the total price of the mobile phone; At the same time, you need to buy products that support installment payment.
3. At present, individual users generally only have credit card installment, and generally do not support personal guarantee purchase.
As for the specific down payment and monthly payment, it depends on the credit card you use. I suggest you consult a credit card bank for details.
As the sales policies vary from place to place, you need to consult your local business office for details.
