"Editor's note" technology advances faster than we ever imagined, when we were still worried about how to protect the SIM card information safe when E-SIM card will be poised. The joint was popularized by Apple and Samsung, the two "enemy" giant on the E-SIM technology come together. Put aside the interests of constituents, we are more curious about is the power of technology.
According to the financial times of London reported, with the exception of supply chain cooperation, Apple and Samsung has started in another area, and actively to persuade operators to tie your own development and to use the new SIM card standard, this new SIM card by using embedded technology (later known as E-SIM), could make it easier for mobile devices in switching between different operators ' networks.
Earlier last year, LTE release of iPad on Air2, a step ahead of Apple by a similar programme, its a Apple SIM card is built-in, users can work directly from a set of equipment to use to purchase data services operator. But apparently, when Apple is only a small step.
On one hand, we see the famous Apple SIM card operator is still relatively limited. And this led to the problem is that the Apple iPad Air2 more SIM cards can only provide experimental, it does not have the capacity to fully convince users abandon external SIM card, so iPad Air2 is still reserved for the SIM card slot.
E-SIM card what is the principle? Michael Kors iPad air Cases
"SIM" name is "Subscriber identity module", or "Subscriber identity module". Its main role is to store data, including some fixed data.
As the international mobile subscriber identity (IMSI), authentication key (KI), the personal identification number (PIN), the MDN (mobile phone number), as well as the SIM card security algorithms and data content, key, network traffic so that users know their identity, found different users and establishing communication and billing in accordance with the appropriate tariff policies.
At the earliest time, CDMA mobile phone there is no SIM card, instead of burning, including early Hai Tao iPhone users also have met the telecommunications unit burned. Zhihou, popular GSM devices become mainstream-although the SIM card for a long time, and did not significantly change the nature of the SIM card.
But led by pioneers such as Apple, SIM from appearance but has "shrunk" trend. Although its scope is limited to the surrounding plastic card tray, but it is easy to see, miniaturization has been successfully validated is a SIM card in the right direction. Even it was suggested that the SIM card should you want to cancel the physical form, transforming it into a software form, for the latter, we call it "virtual SIM card".
And the so-called E-SIM, strictly speaking is not a true virtual SIM card. Its main significance is that if E-SIM card equipment, then users purchase their cards after the device is no longer needed, but directly by software registration or direct purchase and other types of ways you can use your own operator's network and packages.
Prior to that, traditional SIM cards do is locked by means of binding the user in a service network. Integrated E-SIM card, allows users to avoid limitations in the services of an operator.
Let us take a very common case to illustrate the meaning of the E-SIM card, which is roaming abroad.
Assumptions before we are using China Mobile SIM cards and opened roaming service before going abroad if necessary, went abroad, we have access to the local network, local operators will be issued to mobile authentication information. After the user opened roaming service, which creates a difference in virtual IMSI SIM card before, so that we can be ATT's network for authentication by, then we can use its services. However, if we wanted to use local operators and services, still need to apply for a SIM card only.
So now, after you have your E-SIM card, we will not so cumbersome, you can freely choose a different network. And need not be limited by high roaming fees, directly to the local price to enjoy the different operator's service. And implementation, by the agreement between the operators or by negotiated purchase package the terminal manufacturers and operators to provide to the user.
If the SIM card from scratch before, solve the problem of phone users don't get replaced, from the traditional SIM card E-SIM card, solved the problem of is user bound by operators, which not only simplifies the process of user network sign up, also significantly reduced the cost of user changing operators.
Impact on operators
E-SIM card unit and burned many places are similar, but its results are completely different, because their respective symbol of user operators rely on light and heavy.
It is, therefore, from a certain point of view-
E-SIM card for users of the Gospel, is a challenge for operators.
Prior to that, as the only mobile operator to issue SIM cards, global carriers through the SIM card and phone numbers bindings, firmly locking a large number of users, and with users of voice and data consumption and earn big bucks. While SIM card is proof of ID for each user and network, for more than 20 years in, for operators to build a solid defense line.
Based on this, operators gradually developed a monthly rental, packages, as well as subsidies and other business model, as long as users continue to use this number, it must have consumed, in this context, terminal manufacturers are happy to work with our operators, together to urge the Terminal generation, achieve win-win situation.
But are because this, SIM card while is operators of died points, if one day operators no longer can master SIM card has, so also on means with it will was forced to alienated user--E-SIM card of coming, on brings has such a problem, those select E-SIM card of user, may no longer will and a a operators signed Xia long-term contracts, and has may at any time left, and this for operators margins and business mode of effect is is huge of.
So we see that, although the majority of operators have opted to join the embedded SIM card standard to, but for large operators, put the choice to the user is quite difficult, the trend is relatively favorable to service small and medium operators.
Of course, operators have recognized this trend, it does not mean that E-SIM card can quickly fall because this model after all operators a revolution. And though you see Apple and Samsung both world number one or two mobile phone manufacturer's blessing, but since carriers subsidize the factor exists, even if they can only appeal and take the lead model and not necessarily decisive in the development of E-SIM card.
E-SIM cards have hidden it?
Earlier have been introduced E-SIM benefits to the user, it is convenience and freedom was greatly improved, and a decline in dependence on carriers. However, the E-SIM cards are also not completely safe. Because it essentially is the same logic as the original SIM card, just become embedded.
And Qian soon was exposure out of global maximum of SIM card manufacturer Gemalto suffered hacker invasion of event, on proved has SIM card this a was general think is security of system also exists defects and vulnerability, in its itself no for reliable of security upgrade zhiqian, regardless of is outside plug type also is embedded type, results and not has more big difference--certainly has, from big of environment Xia we also is without concerns SIM card of security problem of, more alone it also not hamper we for E-SIM card this revolution of support.
Also worth mentioning is that the E-SIM card as much as virtual SIM card completely, but compared to the virtual SIM card and only a few vendors can master the premise of E-SIM card is clearly more pervasive. Because virtual SIM card to replace the operator's work is feasible from the system or baseband start agreement to bypass carriers, which is why only Apple and few vendors such as Huawei to launch services's sake, but for most companies, and the relatively high threshold for such programmes.
Then the problem came back again, number portability network in the country for many years still in shortage "landing" State of the environment, when we can enjoy this service? Michael Kors iPad Air Case
