Buying mobile phones in installments is a matter for banks and shopping malls that sell mobile phones, and has nothing to do with users. As long as the bank card in the user's hand allows staging, it can be staged. After all, this money needs to be paid in advance by the bank, and the user will pay it to the bank later.

This is the same as buying a mobile phone in installments online, such as buying things in installments on a treasure. A treasure also gives users a credit line, just like an ordinary credit card.

To put it bluntly, it is to see whether the party who prepays the mobile phone is willing to prepay, which has nothing to do with the user's account. After all, there are many channels to pay back the money.
