Although the iPhone13 series is still Apple's latest model, it has been on the market for nearly a year, and there are many refurbished machines on the market.
The iPhone 13Pro Max bought by fans is an expander. iPhone expansion is very simple, that is, take off the small memory and replace it with large memory. The actual operation is very difficult, testing the master's skills. If the master's skills are not good, various problems may occur in the later stage. For example, crashes, white apples, flashbacks, and so on.
The expansion machine may not only have problems in the later stage, but also will automatically give up the warranty and do not maintain the value, so the expansion machine is very cheap. Many merchants will expand the small memory iPhone as a large memory iPhone to sell.
The screenshot is about this iPhone13Pro Max, you can see that the machine is the national bank version, the memory is 1TB, the operator lock is "no SIM card restrictions", "no SIM card restrictions" is very confusing, because the black unlocking machine (with network locks) will also show "no SIM card restrictions", want to know whether the iPhone has a lock, the best way is to query the network lock or the whole machine report.
Next, we look at the whole machine report data queried by fans to see if there is any abnormal data on the machine.
The screenshot is the whole machine report data of this iPhone13Pro Max, you can see that the original memory of the machine is 128GB, but the local display is 1TB, indicating that the machine is a scale-up machine. The activation date is September last year, and there are only more than 50 days of warranty left, but since the machine is a capacity expansion machine, the warranty will be automatically abandoned. Other data is normal, such as ID lock off, no network lock, retail machines, place of purchase China (Bank of China), all Netcom 5G, dual card and so on.
Although the machine is of the best color, it belongs to the expansion machine. It is generally not recommended to buy this flagship expansion machine, after all, the price is expensive, in case of problems, the maintenance cost is also very high. Not only that, but it also depreciates, loses warranties, and so on. When you buy a machine, you should also stay away from the expansion machine.
