For example, if you charge the phone bill and qq, a credit card has a monthly limit of 500.
However, you can consider paying by savings card (provided you have money) or online banking (if the credit card can pay online and you have enabled online payment).
Another way is to find a store that supports credit card (large amount) payment and buy the same mobile phone.
The problem of fast payment (the credit card of any bank in this store is the fast limit of 500 yuan every month) is inevitable, so I have provided you with the above solution, hoping to help you.
