Why doesn't Apple's mobile phone display 4g network?

Apple's mobile phone does not display 4G network. There are the following solutions:

1. Unlock the phone first, then find "Settings" on the page in the phone and click to enter;

2. After entering the settings, find "Cellular Mobile Network" under the settings page and click Enter;

3. Click "Cellular Mobile Data Options" under cellular mobile network data.

4. Click "Enable 4G" under the cellular mobile network page and check only the data.

5. At this time, we found that there was something wrong with the 4G icon.

There may also be the following reasons:

1. The calling card you used was changed to a 4G card before going to the business hall, so the icon of "4G" will not be displayed when it is displayed, but an icon of "E" will be displayed;

If this is the case, you need to go to the business hall where the mobile phone card is located to change the card for free and replace it with the latest 4G card.

2. At this time, your mobile phone is connected to wireless WIFI, so you can only display a WIFI icon without the "4G" icon. When "WLAN" is turned off in mobile phone settings, it can be displayed;

It is recommended to check whether the "4G" icon is displayed after turning off the "WLAN" in the mobile phone. If so, the problem will be solved. If it is not displayed all the time, you need to proceed to the next step.

3. When you turn on Airplane Mode, all networks will be closed. If there is an airplane icon in the upper left corner of your mobile phone screen, it means that you have turned on airplane mode.

I suggest you check whether the plane icon is displayed in the upper left corner of the phone screen, and then turn off the "flight mode" in the "Settings" of the phone.

4. When you are in an unstable network area, your "4G" icon may disappear. The five points in the upper left corner of the mobile phone screen will disappear together;

At this time, the "4G" icon of your mobile phone may also be displayed as "3G" or directly become "E" network. Devaluation means that you are in a weak position in the new mobile phone number. Only by moving to a place with strong signal or an open place can you connect to the "4G" network, and the display screen in the upper left corner will also appear.
