Since the Ministry of Internal Affairs and Communications has been obliged to unlock the SIM in May 2015, used smartphones have become easier to use.With the spread of auction sites and flea market apps, it is easier to obtain.In the case of an iPhone, which is not unusual for users to replace every year, the amount of distribution tends to increase in the fall when new models appear.
When it comes to second -hand goods, the condition depends on how the previous owner has handled, but the iPhone can be considered in a functional sense that it can still be used if it is a model within 5 years from its release.
For example, the iPhone 6s released in 2015 will continue to support the iOS 15, which will be released in the fall of 2021.Although it may not be supported in the next version (iOS 16?), Which will probably be released in the fall of 2022, it can be used as an active model after six years after its release, so the iPhone X, 2018 released in 2017.You can use it for 2 years with the annual iPhone XS.
The problem is a physical condition, and if it has been used for more than a year, some scratches and usability are unavoidable.If you use the battery to about 80%of the initial performance if you use it every day for two years, you should consider replacing it to use used goods used for a certain period of time without stress.
It is OK to bring glass damage and battery replacement to the eight Apple Store in Japan, repair delivery at the Apple Repair Center, or ask a regular service provider certified by Apple.The warranty can also be covered with "Mobile Insurance", which is a small amount of Sakura, short -term insurance.
If you don't want to take time, you can choose an online product.For example, Amazon sells a SIM -free iPhone of recycled, used goods, exhibitions, and opened items that are well -maintained and look like a new one, cleared the tests and tests as "Amazon -maintained products".Why don't you refer to the price level check?
