Before we begin, let's answer a question:
What exactly are frequency bands used for, and what are the consequences of downalling?
Let's first take a look at a model comparison - Huawei Mate30 and Huawei Mate30Pro, which is Huawei's first 5G mobile phone released in 2019. #来点儿干货#
However, there is a big difference between the two phones in terms of 5G band support, let's take a look at the comparison:
The Huawei Mate30Pro supports more frequency bands than the Huawei Mate30, N1, N3, and N28.
If you search for N1, N3, and N28 on search engines back then, if they would have any effect on their use, the answer must be this:
"As long as there is n41/n78/n79, castration of any other frequency band will have no problem for mobile phones to use in China."
This answer stands at the end of 2019, and there is naturally no problem at the beginning of 2020, because the N1 band and N28A band are really not important in that year.
However, by 2020, N1 and N3 were also quickly recultivated from the 4G frequency band to the 5G frequency band by China Unicom and Telecom, and became the necessary 5G frequency band for domestic smartphones. (especially N1)
5G mobile phones released in mid-to-late 2020 all support these frequency bands.
In 2021, Radio and Television announced that it would jointly develop the 703MHz-743MHz low-frequency 5G frequency band with Mobile, that is, the N28 frequency band.
Then if you are a user holding the Huawei Mate 30 Standard Edition, you will definitely be affected during the use of the phone.
Because if your mobile phone does not support a certain network frequency band, and the communication operator in your area happens to be laying a 5G network under this frequency band, then your mobile phone will have the problem of having an empty network but not being able to go to the network.
This situation has appeared in the 4G era.
Seeing this, everyone should have understood that the laying of network frequency bands is definitely not immutable, especially at the moment when 5G is still in the development period.
It will be flexibly adjusted according to different regions, different regions and even different scenarios (more people, sparse people).
Therefore, in general, the more frequency band support the better, and the reason why mobile phone manufacturers want to castrate the frequency band is for only one purpose - to save costs.

At this stage, the flagship 5G frequency band survey, who has the most conscience?
Next, we will compare the support of the 5G frequency band of each brand of high-end machines that are currently priced at 5000 yuan to 7000 yuan.
Because the price has reached this price, it should not be castrated 5G frequency band, there is really no need to save this cost, and many consumers who buy mobile phones at this price also have the desire to go abroad.
The author will divide the mobile phone into different bands according to the number of supported frequency bands, so as to facilitate your choice, and the models participating in the comparison are as follows:
The strongest king: iPhone 15 series
Frequency Bands:
N1, N2, N3, N5, N7, N8, N12, N20, N25, N26, N28, N30, N38, N40, N41, N48, N66, N70, N75, N76, N77, N78, N79
The frequency band support of the iPhone has always been the most complete, because Apple wants to sell in the global mobile phone market, and the frequency bands of various countries must be supported.
So generally speaking, Apple's fragment support is the most complete, which is one of the main reasons why many consumers who often go abroad buy iPhones.
钻石级：荣耀Magic 6Pro
Frequency Bands:
n1/n2/n3/n5/n7/n8/n12/n20/n25/n26/n28(A&B)/n38/n40/n41/n66/n71/n77/n78/n79
GloryMagic6Prosupport195Gfrequency band,Very conscientious,It is also the most complete support frequency band among the current domestic mobile phones,This is something that the author did not expect。
It can also be seen from this that the materials used in the RF front-end chip of the Honor Magic 6Pro are very solid.
IQOO 12Pro
Huawei Mate60Pro:
N1/N3/N5/N7/N8/N20/N28/N38/N40/N41/N77/N78/N79/N80/N81/N83/N84
iQOO 12Pro:
n1/n2/n3/n5/n7/n8/n12/n20/n25/n26/n28/n66/n38/n40/n41/n77/n78
Both the Huawei Mate60 Pro and the iQOO 12 Pro are equipped with 17 5G frequency bands, which are exactly the same in number, however, the Huawei Mate60 Pro supports the N79 frequency band, while the iQOO 12 Pro does not.
There may be some hidden dangers in the future if the N79 frequency band is not supported, after all, N79 is the 5G high-speed frequency band that China Mobile will focus on developing, and it may usher in great development in the future.
白金级:OPPO Find X7Ultra
Frequency Bands:
n1，n2，n3，n5，n7，n8，n20，n28A，n38，n40，n41，n66，n77，n78，n79
The Oppo Find X7 Ultr only supports 15 frequency bands, which is a bit unsatisfactory based on his price and positioning.
Because among the above domestic mobile phones, in addition to Huawei Mate60Pro, the price of OPPO Find X7Ultra is the highest (from 5999 yuan), but the frequency band support is not rich.
Most typically, he also supports N28A instead of the full N28 band, and the machine at this price has to castrate this little thing, which is really ugly.
Gold: Xiaomi 14 Pro
Frequency Bands:
N1 / N3 / N5 / N7 / N8 / N28A / N38 / N40 / N41 / N48 / N66 / N77 / N78 / N79
Xiaomi 14ProSupport 154 frequency bands,The performance is also more average,He also only ate the incomplete frequency band of N28A,The performance is really average。
黑铁级:VIVO X100Pro
Frequency Bands:
n1/n3/n5/n8/n28A/n38/n40/n41/n77/n78/n79
I never thought that among several flagship machines, the most powerful castration frequency band and the most crotch-pulling material turned out to be VIVO, which has always been known for its kindness.
And it's also VIVO X100Pro, the current flagship product of the blue manufacturer, as a comparison, iQOO 12Pro's band support is richer than his, which is what the author can't understand.
End hope it helps
