Definition of 4G on Oppo F21 Pro
4G is the fourth generation of cellular communication technologies, it comes just after 3G and before 5G. Although 5G is considered the highest technology present in the market, 4G is still the fastest most diffused technology.
4G has fast uploading and downloading speeds, exceeding the previous 3G technology, and it also has better latency, allowing users to do much more things using their phones, things such as live conferencing.
To be more precise, 4G is a designation assigned by the International Telecommunication Union (ITU), and it is also a commercial expression used by wireless carriers to express a set of protocols used in their networks.
One of the most famous protocols is LTE and LTE-Advanced, So for Oppo F21 Pro 4G to be useful, it should be suitable with the protocols used by the local wireless carriers.
What are the advantages of 4G on Oppo F21 Pro?
4G has all the functionalities of 3G at more speed. It allows download speeds of around 14 Mbps up to speeds as high as 150 Mbps, five times faster than 3G. And it offers more than ten times the uploading data speeds of 3G, ranging from 8Mbps up to 50 Mbps.
Low latency is another feature, it ranges from 60ms to 98 ms, Even though it’s only a few milliseconds lower than 3G, it is very significant for some use cases such as video conferencing or online gaming, and other live interactions.
The development of VoLTE standard added another feature to 4g technology which is the ability to make phone calls and navigate the internet simultaneously, with even more appropriate voice quality. All of these advantages are within your reach with Oppo F21 Pro 4G technology.
How do you tell whether the Oppo F21 Pro is 4G enabled or not?
Before buying your device you want to make sure that it supports 4G. you have so many options to do it, we will list some of them here. The most obvious way is to check the specifications on the user guide or in the device’s box.
If you don’t have them or you are still lying on your sofa trying to choose the best phone for you, you can do the same on the internet using the device name or model number.
If you desire to verify your current phone, just turn on the mobile data, if the Oppo F21 Pro 4G data is on, then you will notice immediately a 4G sign on the top of the screen. You might see LTE or LTE+ instead of it. However, this way might be deceptive if you didn’t activate a 4G offer, or you are out of coverage.
Another way is to check the settings: open your settings and search for network mode, usually as follows: Settings > Cellular (or Mobile Data) > Cellular Data Options (or Mobile Data Options). If your phone supports 4G you will find 4G option or LTE. If you don’t see either of them, then your smartphone doesn’t support the technology.
How to switch to 4G on Oppo F21 Pro?
If you would like to enable your Oppo F21 Pro 4G network, then follow the instructions (it might change a bit from the settings on your own device):
1- From Home screen, select Apps.
2- From the Apps tab, choose Settings.
3- Select Mobile network.
4- Select the sim card you want to manage (the one used for data if your device is dual sim).
5- Tap Preferred network type.
6- Choose 4G or LTE option.

Get to know 4G bands in your Oppo F21 Pro
A 4G band is a range of frequencies used by mobile network operators. Why this matters to you? It matters since each wireless service provider uses special bands according to the area. And not all mobiles support all 4G bands, so you should assure that your Oppo F21 Pro supports the bands present in your area.
It’s hard to formalize the bands internationally, because each government uses different bands for different radio transactions aside from 4g (such as aeronautics and radio broadcasts). Despite this, the ITU sectioned the world into 3 regions and bands for each region.
The Oppo F21 Pro 4G supported bands are:
1, 3, 5, 8, 38, 40, 41;.
