The HS code-based invoice validationdifference between the American version of iPhone and the State Bank of China iPhone is revealed! With the continuous development of the mobile phone market, iPhone has always been one of the popular brands. Whether it is the American version or the national version, the iPhone has excellent performance and appearance design. However, in some details, there are still some differences between the American version of the iPhone and the national iPhone. In this article, we will reveal these differences together. 1. First of all, the most obvious difference between the supported network types is the network type.The American version of iPhone supports GSM and CDMA networks, while the national version only supports GSM networks. This is because CDMA networks have basically been phased out in China. If you need to use CDMA network in China, you can only choose the American version of iPhone. Two. In addition to the network type, the American version of the iPhone and the Bank of China iPhone use different chips. Because the American version of iPhone needs to support CDMA network, it uses CDMA chips. The iPhone of the State Bank of China uses a global LTE chip. When using a mobile phone, this difference will hardly affect the performance. But if you need to do debugging or testing under certain specific networks, this difference is still very important. 3. In addition to chips and network types, the supported frequency bands also support different frequency bands for the American version of iPhone and the National Bank of China iPhone.In order to adapt to the global market, different versions of iPhone produced by Apple will support different frequency bands. There are several frequency bands between the American version of iPhone and the National Bank of China iPhone. Specifically, in the American version of the iPhone, the supported LTE bands are 1, 2, 3, 4, 5, 7, 8, 12, 13, 14, 17, 18, 19, 20, 25, 26, 28, 29, 30, 38, 39, 40 and 41. In the State Bank of China iPhone, the LTE frequency bands supported are fewer than the American version, only 1, 2, 3, 4, 5, 7, 8, 11, 12, 13, 17, 18, 19, 20, 21, 25, 26, 28, 29, 30, 34, 38, 39, 40 and 41. Therefore, if you need to use your mobile phone in some specific LTE bands, you need to pay attention to this difference.Four. The last difference between the SIM card slot used is the SIM card slot. In the American version of the iPhone, the nano-SIM card slot is used, while the National Bank of China iPhone uses the dual nano-SIM card slot. This means that in the State Bank of China iPhone, you can use two SIM cards, but only one in the American version. In summary, in terms of performance and appearance, there is not much difference between the American version of the iPhone and the State Bank of China iPhone. However, these differences are still very important for users who need to use mobile phones under different networks, or for users who need to use specific frequency bands. If you plan to buy an iPhone, it is recommended to carefully understand your needs before making a decision.
