Nowadays, most mobile phones are pursuing the ultimate slimness, and the picky of the internal space of the manufacturers has caused the SIM card to be “tortured†for many times. However, technologies such as e-SIM cards have begun to become popular on wearable devices. Recently, ARM announced its own iSIM card, claiming that it can integrate SIM cards on ARM-based SoCs to further liberate mobile phone interior space. How does e-SIM technology apply to the smart home and wearable devices? The SIM card is not unfamiliar to everyone. Everyone calls, sends text messages or uses cellular network functions. The SIM card service provided by the operator is indispensable - although the "component" is not large, it contains the user identifier IMSI, Key information such as the KI key and mobile phone number is an essential module for mobile phones. The iSIM card technology announced by ARM, including the securely encrypted hardware area of ​​Kigen OS system, important data cannot be easily extracted; at the same time, it also integrates the processor, baseband and SIM card on the same chip, thus further reducing module space. Its main advantage. In fact, in the era of Big Brother, the SIM card is fixedly burned on the mobile phone, but in this case, the replacement of the mobile phone number is very inconvenient, so most mobile phones now leave a special location and opening to facilitate the card. However, as the mobile phone manufacturers' requirements for internal space become more and more demanding, the slim SIM cards are reduced in size again and again, and the mainstream Nano SIM cards are now no longer than 12 mm in length. The e-SIM card is even more advanced. It can not only be directly integrated into the mobile phone, but also users can change the relevant information on the SIM card on the same mobile phone. In addition to the smaller size, the SIM card can also be removed. Slots leave more room for the internal design of the phone. At present, ARM's iSIM and e-SIM technologies are similar, and the advantages of space saving and convenience of switching numbers are basically the same, and it is also a perfect match for operators to carry out services such as number portability. Moreover, currently mobile phone SoCs mostly use the ARM architecture. Therefore, it can benefit all smartphone users after it is popularized. However, most of the operators are now resorting to all their services to retain their own users. For example, the function of “Xidapu Benâ€, which is called “Turn to the Internet,†will not come online in the short term. Considering that IoT technology also needs the help of mobile networks, visual inspection of new technologies such as e-SIM and iSIM will take the lead in the smart home and wearable devices.
