5G phones are now online. How long can 4G phones last? Can old phones use 5G networks?

With the advent of 5G technology, 5G has become a hot topic in the mobile phone industry. In the second half of this year, major mobile phone manufacturers have begun to promote the release of 5G mobile phones.

In order to seize the 5G market, some 5G mobile phones will be launched earlier. Currently, there are two 5G mobile phones officially on the market, namely ZTE AXON 10Pro 5G version and Huawei Mate20X 5G version. More 5G mobile phones will be launched in the future.

At the same time, the three major operators are also actively promoting the commercialization of 5G networks, and have recently opened 5G experience packages, allowing users to experience 5G firsthand.

Many people are ready to switch to 5G phones to become technology trendsetters. However, some people are still on the sidelines, thinking that the price is too high, and worrying that the current 5G technology is not yet mature. At the same time, they think that the 4G phones in their hands can still last for another year or so.

So, is it appropriate to buy a 5G phone now? After 5G phones and 5G networks become popular, how long can our 4G phones last?

Will 1.5G phones always be so expensive?

Won't

The current prices of 5G mobile phones launched by ZTE and Huawei are slightly lower than the estimated price of 8,000 yuan given by China Mobile last year, but they are much higher than the current common 4G mobile phones. Many consumers find this difficult to accept.

However, with the launch of 5G mobile phones, mobile phone manufacturers will inevitably continue to lower the price of mobile phones in order to seize the market. In addition, after the official large-scale commercial use of 5G in China, 5G prices and 5G network charges will also usher in an adjustment.

It is expected that 5G mobile phones priced at around 1,000 yuan will be launched one after another by the end of 2020. Those who are not in a hurry to try out new things will be able to buy affordable 5G mobile phones next year, when 5G mobile phones will be more mature.

Do I need to change my SIM card to use 5G?

unnecessary

I still remember when 4G first came, professors often received notifications to change their cards. Now with 5G, this is no longer a hassle.

China Mobile said that users do not need to change their numbers or SIM cards, they only need to change to 5G phones and they can use 5G network services in areas with 5G signal coverage. If users want to change their SIM cards themselves, they can also go to the business hall to change them for free.

Users who are not in a hurry to experience 5G networks can continue to use their current 4G phones, and operators can still provide good 4G network support. For example, when the 4G era came, a large number of 2G users were able to use mobile services normally.

Which cities have 5G network coverage?

Unicom APP one-click query

Recently, China Unicom’s mobile business hall App launched the 5G signal coverage query function, which allows quick query with one click.

Open the app, click the "Service" menu at the bottom, select the "Innovation" column, and click the "5G" section to view the 5G signal coverage map of your city. As shown in the figure below, the green circle is the 5G signal coverage area.

Will 5G radiation be very high?

Won't

There are rumors online that 5G radiation is high and harmful to human health, which is alarmist. In fact, 5G base stations, like 4G base stations, must meet the national standard of "less than 40 microwatts per square centimeter", and the radius and power of 5G base stations are smaller than those of 4G, with less radiation.

What really affects us is the radiation from mobile phones. In the 5G era, the density of base stations will be greatly increased, and the probability of poor mobile phone signals will be greatly reduced, and the radiation received by users will actually be reduced accordingly. Moreover, the 5G frequency is non-ionizing radiation, which will not cause harm to human health, so you can use it with confidence.

Regarding the question of whether it is suitable to replace a 5G mobile phone at present, the professor's personal advice is that it is best not to do so yet.

First of all, there are not many 5G mobile phone models to choose from. Secondly, there are still many areas that are not covered by 5G networks. Thirdly, the price is not cheap. But if you have enough budget and want to try something new, it is not a bad idea to change to a 5G mobile phone now.

Users who currently have no intention of switching to 5G phones do not need to worry that 4G phones will soon be eliminated.
