In the era of 3G to 4G, if you still have the impression of friends must remember, you need to go to the business hall to replace the original 3G SIM card with a 4G card, in order to make your 4G mobile phone play 4G bandwidth.
If according to this experience, into the era of 5G mobile phones, the 4G card we originally used does not replace the 5G card, and the 5G mobile phone should also be the speed of 4G. But this is only the experience of some people.
In fact, 5G mobile phones do not need to replace the 5G SIM card, with the original 4G card, you can enjoy the 5G network, but it is best to apply for a 5G package.
5G network in many townships and villages in the mainland has been popularized, for example, the author's hometown is a 5G network, the author is also Huawei's first generation of Huawei 5G mobile phone users, remember to evaluate the 5G rate, but also to Unicom, mobile near the business hall for testing.
The staff of the business hall specifically introduced to this writer that the 4G cards I used could only enjoy their 5G primary rate, which of course doubled the speed of 4G. And introduced to me, although there is no need to replace the 4G card, the 5G rate enjoyed by different packages is not the same.
Then the business hall staff showed me the download and upload rate of the highest 5G package of the 5G display machine in their business hall, which is indeed 1G. And my 4G 10 silver 10G package, the test rate as long as close to 300Mbps or less.
The sales hall staff also borrowed this 5G SIM card from the business hall to use it, and the author used this 5G highest traffic package card to test the first generation of Huawei 5G mobile phones outdoors, and the comparison test with the iPhone 4G mobile phone really felt the 1G speed of 5G.
The staff of the business hall is still very funny, after the test, he also said that this 5G card is not personal, if it is personal, so run the test, they are reluctant to do it, after all, the package cost is not cheap.
Here to say more, 5G SIM cards can also be used on 4G mobile phones, but only 4G rates can be used.
To sum up through your own experiences:
5G mobile phones do not need to replace the original 4G SIM card. But if it is a 4G package, the use of 5G mobile phones can only enjoy the 5G primary rate provided by the communication provider.
If you want to enjoy faster 5G speeds, you need to apply for a higher level of 5G package instead of replacing the original 4G card.
