The continuous advancement of technology, the rapid evolution of technology and the rapid development of your safety, have been pushed to the next node. Just like now, when we are still worried about SIM security, e-SIM is coming. Look at the e-SIM's upcoming battle, feel that it really is coming, and it will be very fast. Why is this? Because Apple and Samsung are together to promote this matter.
According to the British "Financial Times" report, Apple and Samsung are conducting "high-level dialogue" to discuss the use of e-SIM cards on their own smartphones, allowing mobile phone users to switch communication carriers more flexibly.
Although everyone often uses SIM as a small plastic card in real life? Can you really understand the SIM card? And what about e-SIM?
The SIM card is an abbreviation of (Subscriber IdenTIty Module), also known as a user identification card, a smart card, and the GSM digital mobile phone must be equipped with this card. The information of the digital mobile phone customer, the encrypted key and the user's phone book are stored on the computer chip, which can be authenticated by the GSM network client identity and encrypt the voice information of the customer during the call.
The SIM card is a chip card with a microprocessor. It has five modules inside, and each module corresponds to one function: microprocessor CPU (8 bits), program memory ROM (3 to 8 kbit), working memory. RAM (6 to 16kbit) data memory EEPROM (128 to 256kbit) and serial communication unit.
The so-called e-SIM card is a virtual SIM card, similar to Apple's previously released Apple SIM card, which is embedded in the phone, allowing iPad Air 2 users to switch operator services. It sounds like the e-SIM card is a bit like the CDMA burning code a long time ago. The burning number refers to the input of the data provided by the operator into the mobile phone, so that it can be used in the network. The previous CDMA parallel mobile phone is often used. If we remember correctly, the Apple iPhone 4 used to support the burning number.
This e-SIM card is similar to the Apple SIM card, or it can be considered as the continuation of its Apple SIM card. This virtual SIM card is not suitable for Apple devices like the Apple SIM card. It will be suitable for Apple and Android. Multiple platform devices, that is, e-SIM cards will become a common standard, and now Apple and Samsung are pushing this standard. This standard may be introduced next year.
Having said that, in the end, what is the impact of the cancellation of the physical SIM card and the application of the virtual SIM card to operators and users?
Obviously operators are not very welcome for the following reasons:
First, the large-scale carrier users were diverted. Because the e-SIM card is the biggest difference compared to the mobile phone SIM card that is commonly used today, it is no longer fixedly bundled with a telecom operator.
Second, the use of a virtual SIM card means that the operator's revenue is not insured. When the physical SIM card is locked in the service of an operator, the user is equivalent to a long-term agreement with the operator. Each operator has a large number of long-term contracted users. By serving this large group of users and providing network services such as data consumption, operators can seize a lot of wealth. Over the years, operators have relied on physical SIM cards to generate huge profits. The arrival of the e-SIM card is tantamount to stealing food from the operator's mouth.
When the user has the initiative and can change the service of the operator at will, then the "long-term contract" system will be disintegrated in the past years, the operator's revenue and profits will be affected, how do you want them to warmly welcome?
What practical benefits will the application of the e-SIM card bring to the user?
The first is the freedom of the operator to switch. Traditional SIM cards "lock" users on a network, but embedded SIM cards will allow smartphones, tablets or wearable smart device users to avoid being locked into a carrier's communication plan, but You can quickly switch networks.
The second is to say goodbye to the high roaming charges. If we travel abroad for a while, if we are using a traditional physical SIM card, then we will choose to open an international roaming service to continue using the network. If we want to use local carrier packages and services, I am sorry, you need to re-apply a physical SIM card.
However, the situation of the virtual SIM card is different. The user does not need to apply for a physical SIM card, and does not need to be restricted by the high roaming fee, and can enjoy the services of different operators directly at the local price.
Third, there will be more slim phones available in the future. Now, slim phones are also concentrated on high-end flagship models, and the low-end is generally thick. In addition, after the SIM card slot is removed, the saved space can be placed in other parts. In addition, many netizens said that it is very good to cancel the physical SIM card, saving the cost of a replacement card or card replacement.
For hardware manufacturers, including Apple and Samsung, on the one hand , it can avoid the bargaining with the operators on the contract machine problem, and the lack of a SIM card will help to further make the ultra-thin products even more. Close to the flaps.
Implement the resistance and power of virtual SIM
After the launch of the new iPad in October last year, Apple quietly built an "Apple SIM card" in the 4G version of the iPad, users can get a piece called Apple SIM when they buy two carrier versions of the iPad tablet. Universal SIM card. In the United States, the use of such a SIM card allows the iPad to avoid the hassle of switching operators, and is used in areas where the original operator signal coverage is not good.
For Apple SIM cards, the response from operators is this. Both T-Mobile and Sprint in the US allow users to switch, but some operators do not cooperate. Verizon Wireless does not even join the Apple project. AT&T is the only operator to lock "Apple SIM", but once the user switches to AT&T network, This card will lock the network and you will not be able to switch back to other networks.
Virtual SIM cards are just beginning to sprout, and their standards have not yet been established. It is not easy to replace physical SIM cards with a history of about 20 years. However, due to the participation and promotion of the Global System for Mobile Communications, some analysts believe that the implementation of electronic SIM cards may be smoother.
The GSMA (Global System for Mobile Communications), representing global mobile operators, may soon announce an agreement to produce a standard embedded SIM card for consumer devices that will bring smartphone manufacturers Also covered. The GSMA said: "Most carriers have been involved, so the current plan is to finalize the technical architecture for developing end-to-end remote SIM solutions for consumer devices, which is expected to be delivered in 2016."
In addition, there are other voices of opposition and questioning. For example, operators will lose control of the market, but Apple and other equipment manufacturers may take the right to seize this position. If the regulator allows it, they may have sufficient power to decide which operators to choose after purchasing the phone. Therefore, the demise of traditional physical SIM cards may reduce market choices and even impose higher price burdens on users.
Some netizens said that with e-SIM, if the phone has a problem, the user may not be able to change the card in time. In addition, if the phone is lost, then how to solve the problem of the card. But don't worry about the security of the e-SIM card, because the logic of the e-SIM card and the SIM card are the same, but it is external and has become embedded. It has not been improved in terms of security. It is the same as the traditional SIM card. Certain security holes.
