card sticker is not only cheap but also cost-effective. What should I pay attention to or is it bad?
common points:
American version card sticker is also an authentic original machine. The parts used are the same as those used in the national bank, and the quality inspection standards are higher than those in the national bank, but the version code and sales area are different.
Everyone must pay attention to that there is another particularly prominent problem with the US iPhone, that is, the "code-changing capacity expansion machine". Many merchants will change the US iPhone to a national bank and then expand it to make greater profits. This kind of machine cannot distinguish whether it is the appearance or the data inside the machine. You can see the data displayed by the GSX data of the machine verification detective.
Different points:
1. The US version is both single card, and the card sticker is no exception. It needs to be inserted into the card slot with a "card sticker" and a phone card. It can only be used normally after activation through the card sticker.
2. Will the chance of sticking the sticker be locked and turned into bricks? The answer is "No!" At the same time, the sticker can also upgrade the system normally, and there is no need to reactivate it after upgrading. The system can be restored normally, but after restoring, you need to reactivate the sticker. For ordinary people, the phone may not be restored after using it for one or two years, so it basically has no impact.
3. Signal problems, through actual measurement, the signal is normal when used in urban areas, but in rural areas or in mountains, the signal will be unstable, and it takes one to two minutes to reactivate.
Generally speaking, with the current card sticker technology, there is still no problem with using card sticker. For example, the iPhone 13 pro max card sticker is about 2,000 cheaper than the Chinese market, and the lowest is about 5,000 yuan.
