How to Turn On 5G on OPPO F21s Pro 4G

5G is the most modern communication standard that provides users with qualitative communication and ultra-fast Internet. Compared to 4G, fifth-generation networks show a significant increase in network speed and a decrease in delay. Therefore, for better network quality, you need to activate 5G on your OPPO F21s Pro 4G.

Enabling 5G on OPPO F21s Pro 4G

By default, the smartphone automatically connects to fifth-generation networks if appropriate coverage is available. if this does not happen automatically, in the settings of the smartphone there is an option to force connection to 5G networks. However, battery consumption may increase. Therefore, if you are not satisfied with the speed of the Internet, you need to manually enable 5G on OPPO F21s Pro 4G

1. Open your phone settings.

2. Go to SIM cards & mobile networks.
3. Select the SIM card for which you want to configure 5G.
4. Go to Mobile Networks.
5. Select “Prefer 5G”.

If 5G is not in the list of available networks, your device does not support fifth-generation networks. You can only use 4G networks.

Why 5G is not supported

If the Android smartphone has support for fifth-generation networks, but the Internet is still accessed through 4G or 3G, there are several reasons that do not allow you to use the Internet at maximum speed.

SIM card does not support 5G

5G networks should be supported not only by a smartphone, but also by a SIM card installed in the device. Therefore, you need to contact the office of the mobile network carrier for free replacement of the SIM card. After that, 5G should work on a smartphone.

No 5G coverage in the area

One of the reasons for the problems when connecting to fifth-generation networks is the lack of coverage in the area.

Frequency range is not supported

Supporting 5G networks with a smartphone and being in the coverage area does not mean that you will be able to use fifth-generation networks - the n79 range (4.4-5 GHz). A few smartphones have its support. You can check whether your OPPO F21s Pro 4G supports this range on the manufacturer's website.
