2. credit card installment depends on your credit card limit. Only when the credit card amount is sufficient (Unicom's business outlets are equipped with credit card machines) can you purchase the machine by credit card. It is suggested that it is more favorable to purchase prepaid phone bills. After that, you will have to work hard to pay off the credit card debt. This is your business with the bank, not with Unicom. If the bank lends you money, it will certainly charge you interest. Credit cards can apply for installment payment, but only if the application is approved. If it fails, it can only be repaid in full or 10% per month. If you can't repay in full, the bank will charge high interest every month. 10000 yuan debt interest is about 200-300 yuan/month. Until the repayment period is paid off, the loan can be recycled without interest. Specifically, it is the bank that handles the card.

3. It is suggested that the landlord consider the second-hand IP4, and the IP5 will come out soon. IP4 will be used more and more soon. I believe in the quality of MAC, as long as it is genuine. Second-hand is also easy to use, of course, it is recommended to go to the IP forum to learn how to identify and understand the knowledge of IP before starting.

Of course, if the landlord can accept high interest, he can also buy a new machine directly.

This is a personal suggestion for you. By the way, the threshold for applying for a credit card in a small bank (Guangfa, Minsheng and Xingye) is lower and easier to handle, but it is better not to use it if it can be used. You will only spend all the time and then become a slave.
