It's very simple, find a place with a good signal and it's automatic. The selection of the network is made automatically by the mobile phone and does not need to be manual!

1.Please make sure that all of the following conditions are met:
The SIM card is a 4G card that supports the 4G network (make sure that the 4G service is enabled, consult the carrier for details).
SIM card with 4G data activated**.
Please make sure that the 4G switch is turned on (some mobile customized models do not have a 4G switch, and the system turns on 4G by default).
Please use the standard SIM card provided by the carrier, cutting the card or non-standard SIM card may cause the phone to not work properly. If you have a new SIM card, call your carrier**, refresh your background data, refresh the data, restart the phone and try again.
2.If you still can't use the 4G network after meeting the above conditions, please try:

Summary. 1.Falling from 4G to 3G may be because the network settings of the mobile phone are set to 3G mode, resulting in the signal of the mobile phone becoming a 3G network, you can check whether the network settings of the mobile phone are 4G
How did the mobile phone 4G become 3G + Huawei.
Hello, it's an honor to answer your <>
Are you saying that mobile phone signal 4G becomes 3G?
How did my Huawei phone 4G become 3G.
1.Falling from 4G to 3G may be because the network settings of the mobile phone are set to 3G mode, resulting in the signal of the mobile phone becoming a 3G network, you can check whether the network settings of the mobile phone are 4G
2.It is also possible that there is a problem with the 4G network signal in the place, due to the poor 4G network signal and incomplete coverage, resulting in the mobile phone signal becoming a 3G network, you can change to a place with a good signal and take a look.
3.There may also be a problem with the mobile phone system, you can restart the mobile phone to try, if the system is not the latest version, you can update the mobile phone system to try.

The coverage rate of China Unicom's 4G network is indeed not as good as that of mobile. Especially in some weak signal areas, it is often possible to jump from 4G to 3G and cannot access the Internet, because it is too far away from the base station, the mobile phone is at the junction of 4G signals, or there are multiple base stations in the area, resulting in unstable signal reception. China Unicom 4G jumps to 3G and can't access the Internet, what is the specific reason, and how to restore the 4G Internet access mode?
1. The signal is unstable and causes the jump of 3G
This is because the phone receives multiple weak signals, and the signal is interfered with by the strong 3G signal. At this time, turn on the airplane mode, search the 4G network again, and set it to 4G priority in the phone settings, you can avoid the interference of the 3G signal. If it really doesn't work, shut down and restart.
2. Jump 3G when playing **, unable to access the Internet.
If you do not activate the VoLTE call function, it will automatically switch to a 2G 3G network when you call, and you will not be able to access the Internet. At this time, it is necessary to turn on the Unicom VOLTE function, VOLTE is based on the 4G network for high-quality voice, **calls, and the network will not be interrupted when calling.
3. Check the SIM card status. As.

This isn't something you can switch just if you want to. First of all, it is necessary to explain what model your Apple phone is, whether it is a 4G phone or a contract phone, or something else.
3G network, either the mobile phone does not support 4G network, or the card does not support 4G network, and the signal is not good, it may also be 3G network, not you can switch if you want to.

You can switch networks in the settings, taking Apple 12 as an example, here's how:
1. Click the settings icon on the desktop of the mobile phone.
2. Click "Settings" and find "Cellular".
3. After clicking on "Cellular Mobile Network", you will find that the mobile phone signal appears as 3G or E.
4. Then, click "Start 4G", and the phone can use the 4G network.
It's really good, a good article that lights up.
What are the advantages of 4G over 3GFirst of all, compared with 3G communication technology, the most obvious advantage of 4G communication technology is call quality and data communication speed. At present, the most mature technology in the 3G standard is WCDMA, which can bring users a data transmission rate of up to 2Mbit S, which can be achieved by the CDMA2000 system. The WCDMA used by Japan's NTT Docomo and J-Phone can reach a rate of 8Mbps. But compared to the transfer rate of 4G, this is really nothing. >>>More
The 4G network became the 3G network, probably because the base station construction in that place was relatively far away at that time. The internet signal is not very good.
The signal cannot be shielded, and 3G mobile phones use 4G cards, and only 3G networks can be used. If there is no 3G network in the local area, I will switch to a 2G network.
