The Super SIM card was officially launched in Macau, China.
This time, the first to be listed are 32GB and 128GB capacity specifications. China Telecom (Macau) has also designed a "data card package" for users of super SIM cards, which combines traffic packets to make large capacity and large traffic a card.
It is understood that this super SIM card has three advantages of super capacity, easy to change the machine and save money and convenience: the SIM card itself has 32GB, 128GB super capacity for you to choose, you can save photos, videos, apps, and data. You can also easily back up important information to the card. Switch machines, smooth transitions. Get a lot of capacity and local data traffic in Macau. Large-capacity storage can be used sustainably, the replacement of the machine does not change the card, and the environmental protection is not wasted.
In fact, not only China Telecom, China Mobile and China Unicom have also launched similar super sim cards before. They are all in the form of an additional memory card on the basis of the existing SIM card.
Compared with the storage capacity of traditional SIM cards up to 512KB or even 128KB, super SIM cards can further expand the storage space of mobile phones. And without taking up the internal space of the mobile phone, combined with a series of encryption and cloud services launched by operators, it can improve the security of the user's core data.
In addition to this "self-storage" super SIM card, there is currently a super SIM card on the market. This SIM card contains an encryption chip and NFC function, which can be used as a meal card, access control card, transportation card, car key offline; financial security authentication, 5G electronic signature and large transfer can be carried out online.
At present, some areas have opened such super SIM card services, such as Chongqing Mobile's super SIM card, in terms of transportation travel, Chongqing Mobile and Chongqing Tongka Company cooperation, opened a super mobile phone card based on the livable and smooth card function, take The Chongqing bus or rail, you can directly swipe the mobile phone to ride, no need to scan the code, no need to open other APP, online recharge payment is more convenient, and enjoy the same preferential treatment as the physical bus card.
In addition, based on the high security level and digital authentication capabilities of the super mobile phone card, it can provide security products and security applications such as mobile phone authentication, SIM shield, and mobile phone signature to government and enterprise customers. At present, Chongqing Mobile has cooperated with some communities and banks to realize functions such as community access control mobile phone swipe card and bank U shield through super mobile phone cards.
At present, based on the traditional SIM card service, mainstream operators have made a lot of efforts in the application and function expansion of SIM cards. Even China Telecom has previously launched SIM cards that support quantum encryption. For use scenarios, CITIC Guoxin said that it can be used for quantum encrypted calls, quantum encrypted video calls, quantum security VPN access, quantum security mobile office, quantum security financial payments and so on.
However, although operators are vigorously promoting the value-added services of SIM cards, from the perspective of the situation of the whole industry, eSIM services are already the trend of the times. Whether or not a physical SIM card should exist in the future has been a topic of discussion in the industry for many years. The reason why operators are currently playing so many tricks on the application of physical SIM cards is that they still hope to be able to set aside physical SIM cards.
Whether it is storage or card swiping, the super SIM card business has begun to promote in many places. If you have this need, you can call the operator to inquire about the relevant services. Especially for some entry-level or old mobile phones, some face insufficient storage or no NFC function embarrassment, it may be much more convenient to do a super SIM card.
