The biggest difference between Ziguang Guowei's super SIM card and our commonly used SIM card is the storage space. Generally, the capacity of SIM card is about 5 12K, so we can use it to store contact information, and Ziguang Guowei's super SIM card has the largest storage space of 128G. In addition to contact information, we can also build many functions such as notes, calendars, and mobile phone backup into the super SIM card.
At the same time, the super SIM card has security qualifications such as UnionPay security and state secrets, which can effectively prevent information leakage and theft.
However, Ziguang Guowei's super SIM card is different from the traditional SIM card in appearance. Compared with SIM card with storage function, it is more like a Micro SD card with call function.
Comparison between Micro SD card and Nano-SIM card.
This appearance leads to that this super SIM card is not suitable for the flagship mobile phones of various manufacturers, and only low-end models supporting Micro SD cards such as Huawei Mate 10, Glory Note 10, Xiaomi1Youth Edition 5G, Red Rice Note 10 5G can be used (please refer to the official WeChat account tweet for specific models)

In addition to Ziguang Guowei, which cooperates with China Unicom, China Mobile has also launched its own super SIM card, the size of which is the same as that of the traditional SIM card, but it has the functions of swiping the bus and subway, entering the community and opening a bank SIM card shield (supporting Shanghai Pudong Development Bank and China Bank), but these functions can only be realized if the mobile phone also supports NFC.
Compared with the special shape of Ziguang Guowei Super SIM card, China Mobile's Super SIM card is indeed more suitable. However, most NFC-enabled mobile phones have their own bus cards and access control functions, which makes the application scenarios of super SIM cards compressed: mobile phones come with them, so why replace SIM cards and install more apps?

From the function point of view, the super SIM card is indeed "super" compared with the traditional SIM card, but its function upgrade is not simply to improve the exclusive ability of communication or other SIM cards, but to integrate more existing mobile phone applications into the SIM card, although in many related articles, super SIM cards with large storage, transportation cards, access control and one-click phone replacement will make Internet companies "flustered". However, either not supporting the expansion of the flagship mobile phone or having a transportation card that conflicts with the NFC function of the mobile phone will only make users feel embarrassed when replacing the super SIM card.
Compared with the China Mobile Super SIM card with similar appearance to the traditional SIM card, I was more interested in the Ziguang Guowei Super SIM card with different appearance and "small batch shipment", so I took my red rice note10.5g to the cooperative Unicom business hall mentioned in the official WeChat account of the Super SIM card.
If you are a Beijing user, you can also apply online.
However, several cooperative business halls nearby all said that there is no super SIM card now, and the company has recycled all unsold super SIM cards before the end of 2020. At the same time, the enthusiastic clerk looked at my red rice Note 10 and Xiaomi 1 1 Ultra and reminded me: "Only mobile phones with memory cards can use super SIM cards. 」
The top millet 1 1Ultra was beaten here.
I didn't successfully apply for Ziguang Guowei Super SIM card, so I turned my attention to China Mobile's Super SIM card. Compared with Ziguang Super SIM card, it is much more convenient to handle in the business hall (except Beijing), and it is also much more convenient to handle China Mobile Super SIM card directly on the mobile phone.
Download China Mobile app, "Classification >" You can see the super SIM card processing interface in the number card, enter your identity and address information, and the staff will go to the site to activate the SIM card for you. The overall experience is no different from handling an ordinary mobile phone card.
After getting the mobile phone card, we tested it many times. First of all, let's put the mobile phone card into Red Rice Note10.5g, which does not support NFC function, to see if our understanding of the function is not in place. When I opened the bus card processing interface in Red Rice Note10.5g, the dialog box "Cannot use related functions" popped up, which means that the super SIM card cannot display the "super" function on the mobile phone that does not support NFC function.
On Xiaomi 1 1 Ultra, you can finally use the super SIM card to brush the bus.
After a little investigation, I found that I need to find the NFC setting item in the settings and change the default wallet to "SIM card wallet". This operation was actually done when I applied for an account, but the setting item that Bao app jumped to at that time was NFC's "contactless payment" setting.
Moreover, the whole operation has always reminded me that I need to log in to the "Bao" app (start operating in the "China Mobile" app) and need real-name authentication (after downloading the "Bao" app), which forced me to operate again many times.
There was also an episode when I went to the subway station for a test. Mobile phones that have been set according to the app prompts cannot be swiped directly.
After a little investigation, I found that I need to find the NFC setting item in the settings and change the default wallet to "SIM card wallet". This operation was actually done when I applied for an account, but the setting item that Bao app jumped to at that time was NFC's "contactless payment" setting.
However, it was worth the money, and I still finished the bus card. Whether I swipe my card into the station successfully or swipe my card out of the station after I turn off the phone, it makes me feel that "the technology is amazing."
This excitement only lasted until the moment I walked out of the subway station: although the most intuitive experience upgrade of the super SIM card is to swipe the bus card, there is no reason for me to change a SIM card just to swipe the bus with my mobile phone. Mobile phones without NFC function can't use super SIM card, and mobile phones with NFC function can naturally use the bus card function that comes with the mobile phone more conveniently.
However, compared with Ziguang Guowei's super SIM card, China Mobile's super SIM card can be used with traditional SIM cartoons, which seems to be more popular. In June this year (202 1), China Mobile announced the centralized procurement results of super SIM card products from 202 1 to 2022. * * Seven companies have won the bid and are expected to purchase 1.65438. Although the "Super Campus Card" launched by Guangzhou Mobile and Zhejiang Mobile still needs the NFC function of mobile phones, it integrates campus card functions such as punching in class, dormitory access control and borrowing books, which is relatively friendly.
If you are a digital product enthusiast, you may remember that Meizu Zero was released by Li Nan, then senior vice president of Meizu Technology, on a desk in June 20 19. Its biggest feature is that it is completely non-porous, and the SIM card is solved by e SIM scheme.
ESIM embeds the traditional SIM card directly into the device chip, so we don't need to insert a physical SIM card. Users can choose carrier packages more flexibly, but eSIM has not been applied to mobile phones in China, and we can only see the shadow of eSIM cards on smart watches and smart bracelets.
In fact, besides eSIM, there are many members in the SIM card family, such as vSIM and softSIM. The vSIM card is a virtual card, but it needs a seed card as an "ignition card", so it still needs a card slot. SoftSIM, on the other hand, can access the Internet without a physical card slot.
For example, Xiaomi's global Internet access function is vSIM card technology.
From Mini SIM, Micro SIM to Nano SIM, from physical card insertion, only card slot, embedded devices to completely card-free Internet access, the development direction of SIM card is getting smaller and smaller until it disappears. Super SIM card is not like the future, but more like the "Pro version" of the existing Nano SIM card: in the existing form, more functions are added, such as storage space, bus card and so on.
However, as mentioned earlier, the Ziguang Super SIM card with storage function does not support the flagship mobile phone; China Mobile's super SIM card must have NFC function, and the customized campus card function is really attractive to the student party, but it is not necessary for consumers to replace the SIM card by swiping the bus card, backup system and other functions that the mobile phone itself can do.
Don't use "5G" to represent the future, and don't use "super" infinity. For operators, super SIM card may be a way for them to recapture some markets from Internet companies and mobile phone manufacturers, but for users, it is just an embarrassing choice.
