reversal! China Telecom: use 5g network or need to replace SIM card
China Telecom said 4G card does not meet 5g protocol standard, 5g or need to change SIM card
Upgrade 5g to change card? China Telecom: just 5g mobile phone
Original title: “5g or mobile card to be replaced” behind the hot discussion is the user experience doubt
These two days, entitled “reverse! 5g or SIM card needs to be replaced, 4G card can not meet 5g security requirements “, reported on the Internet. A white paper released by China Telecom recently pointed out that at this stage, when users access 5g network through 4G card, problems such as inaccurate location information may occur, which can no longer meet the information and security requirements of 5g network, the report said.
As soon as the news came out, it immediately aroused widespread concern among users that they should “use 5g to change cards”. China Telecom quickly clarified that the existing 4G users do not need to change their cards, as long as they change into 5g mobile phones, they can use 5g services in the areas covered by 5g signals; China Telecom 5g SA security enhancement SIM card is mainly for industrial application scenarios with higher security enhancement needs, such as intelligent manufacturing, Internet of vehicles, telemedicine, smart city and other fields.
For many users, changing a mobile phone card is undoubtedly a hassle – attached to the SIM card are many important personal information and communication, social resources, etc. Because of this, “5g needs to change the mobile card” will affect so many people’s attention.
Nowadays, China Telecom’s doubts dispelled many people’s doubts, but some people are worried that not changing the card means that they can’t enjoy a more secure and high-quality 5g network service?
It’s worth noting that when 5g technology is just coming into commercial use, operators promise to use 5g service without changing card or number. It was only in June last year that the Ministry of industry and information technology issued 5g commercial licenses to China Telecom, China Mobile, China Unicom and China Radio and television. Now the real “5g first year” is not over. If there are changes in the quality and content of 5g service experience, people will inevitably have ideas.
For the vast majority of ordinary users, whether 4G SIM card can be more compatible with 5g network with higher quality or not is probably more a problem that needs to be solved by technical experts or operators. In the market of information asymmetry, the propaganda of operators plays a great role in guiding users.
Because of the convenience that operators claim that 5g network can be used “without changing card or number”, the enthusiasm of users to buy 5g mobile phones is high.
China’s mobile phone China mobile phone market has seen novel coronavirus pneumonia, which has reached 30 million 441 thousand units in total 5G mobile phones in China from 1 to April this year, accounting for 33.6% of all mobile phone shipments, and 65 new models listed in the total market, accounting for 47.4% of all new models, according to the statistics of China Communications. That is to say, nearly half of the new mobile phones currently on sale are 5g mobile phones.
However, even when 5g mobile phones have begun to sell, due to the limitations of communication infrastructure and technology, many 5g mobile phones still have many problems in high-quality experience, which is a certain gap from the ideal state.
It is gratifying that in order to hedge the impact of the epidemic on the economy, China’s new infrastructure, represented by 5g infrastructure construction, has obtained a rare development opportunity, and the problems such as the lack of base stations that restrict 5g development will be solved in a relatively short time.
But the improvement of infrastructure construction also needs high quality 5g service level. This includes minimizing the trouble of changing card number and so on, so that users can enjoy 5g service more conveniently.
If you don’t change the card, you won’t be able to enjoy high-quality and safe 5g service, so whether the cost of replacement is borne by users themselves or by operators is obviously a problem worth facing.
In essence, behind this hot discussion, what users hope is that operators can provide better services and fulfill the previous service commitment, rather than using the card replacement package and more charging items as the “chain set” to enjoy complete and high-quality 5g services.
Therefore, operators should also provide users with certain and complete information, dispel all kinds of guesses and doubts caused by it as soon as possible, and stabilize users’ expectations through service upgrading. In this way, the development of 5g market will be more smooth.
