Look at what version of the phone it is, not what model it is, there are versions that support 4G, and there are versions that support 3G and don't support 4G.

The Samsung Galaxy Note3 listed in Chinese mainland currently has 6 models, namely N9002, N9006, N9008, N9009, N9008V, N9008S, of which:

It is a Unicom 3G dual-SIM dual-standby mobile phone, and only card slot 1 supports Unicom's 3G network.

It is a Unicom 3G single-SIM mobile phone that supports Unicom 3G.

It is a mobile 3G single-SIM mobile phone that supports mobile 3G.

It is a 3G telecom dual-network dual-standby mobile phone, card slot 1 supports 3G telecom card, card slot 2 only supports China Mobile card and China Unicom card 2G network, does not support 3G network.

It is a mobile 4G single-SIM mobile phone, which is converted to 3G in places where there is no 4G signal coverage.

It's dual-band

Single-band and dual-band WiFi

There will be two situations for the current device, which only supports single frequency and dual frequency at the same time.

Because microwave ovens, Bluetooth, cordless**, etc. all work in this frequency band, and the wifi network card that supports a single frequency only supports the front holding, that is, it only supports working in this frequency band, that is, it will conflict with the three situations described above, because there are only 3 20m channels that do not overlap each other in this frequency band, and mutual interference is very serious.

The dual-band wifi network card can be supported, and sometimes it is also identified as supporting the defeat of Zheng Qing. It can work in the 5GHz band, which is much cleaner, and in this band, there are 5 20m channels in China that do not overlap each other, which can easily avoid interfering with each other.

How to distinguish between single-band and dual-band wifi

When we compare the two logos, we can see that there is only one "a" between the two logos. Although this "A" is actually useless, and the base cong has been eliminated, we can see from the development history of wifi that it is defined on the 5GHz frequency band, so this "A" indicates that this network card can work on 5G. There is a difference between operating on the 5G band and operating on the frequency band.

That is, it can work on the frequency band or on the 5G frequency band, so just looking at the "N" cannot determine whether this network card is a dual-band network card. And "A" can only work on the 5G frequency band, so if there is this logo, it must be dual-band.
