Mobile technologies have developed enormously, One of the main developments is the development of 4G technology. It’s a word that you’ve surely encountered in your daily life, but what is 4G? And is Oppo A9 (2020) 4G enabled? We are going to answer these and other questions related to Oppo A9 (2020) 4G technology in the following article.
Does Oppo A9 (2020) have 4G?
Yes. The Oppo A9 (2020) is able to use 4G Network.
Get to know what is 4G on Oppo A9 (2020)
4G is the fourth generation of cellular communication technologies, it comes just after 3G and before 5G. Although 5G is considered the fastest technology available in the market, 4G is still the fastest most spread technology.
4G has fast uploading and downloading speeds, overstepping the previous 3G technology, and it also has lower 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 term used by telecommunications companies to express a set of protocols used in their networks.
One of the most famous protocols is LTE and LTE-Advanced, So for Oppo A9 (2020) 4G to be useful, it should be compatible with the protocols used by the local mobile network operators.
What are the advantages of 4G on Oppo A9 (2020)?
4G was developed to offer a more reliable internet connection on mobiles, and that’s clearly what it did. 4G technology grants much better downloading and uploading speeds than 3G.
The average 3G speed ranges from 1.5 to 9 Mbit/s, while the average 4G internet speed is between 15 to 90 Mbit/s, it can reach as high as 900 Mbit/s.
Another vital criterion of 4G, is its low latency. We can promote latency as the time needed to send data or the delay between the action and the actual response. Lesser latency means a better user experience. 4G Latency is better than 3G by double. The average 4G latency is 50 ms.
With the assistance of the VoLTE standard, 4G now presents better voice quality in phone calls and gives users the capability to surf the internet while making calls.
All of these advantages combined with the low cost of 4G extended the use of Oppo A9 (2020) 4G technology, to include better video conferencing, online gaming, and other real-time interactions.
How do you tell whether the Oppo A9 (2020) is 4G capable or not?
Before buying your phone you want to make sure that it enables 4G. you have so many options to do it, we will list some of them here. The most obvious option is to check the criteria on the manual or in the phone’s package.
If you lost them or you are still lying at home trying to find the ideal device for you, you can do the same on the internet using the device name or model number.
If you would like to check your current phone, just turn on the cellular data, if the Oppo A9 (2020) 4G data is available, then you will see immediately a 4G sign on the top of the display. You might notice LTE or LTE+ instead of it. However, this method might be misleading if you are not on a 4G plan, or you are out of coverage.
Another way is to check the settings: open your settings and fetch network mode, usually as follows: Settings > Cellular (or Mobile Data) > Cellular Data Options (or Mobile Data Options). If your phone is 4G enabled you will find 4G option or LTE. If you don’t see either of them, then your smartphone isn’t 4G capable.
How to switch to 4G on Oppo A9 (2020)?
If you intend to activate your Oppo A9 (2020) 4G network, then follow the instructions (it might change a bit from the settings on your own device):
1- From Home screen, tap Apps.
2- From the Apps tab, tap Settings.
3- Choose “SIM card & mobile data” or “Dual SIM & Cellular Network”.
4- Select the sim card you want to manage (the one used for data if your device is dual sim).
5- Select Preferred network type.
6- Choose 4G or LTE option.
Note: If you intend to switch off 4G then choose an inferior network type (3G for example) or tap Only 5G if it’s possible.
Get to know 4G bands in the Oppo A9 (2020)
4G and other cellular networks use radio waves to transfer data. These waves have different lengths and frequencies. To prevent interference between signals, governments and the ITU decided which regions use which frequencies for 4G.
Each region has been allocated certain frequency intervals termed bands. Band number 7 and band number 28 (as an example) are used all over the world.
What you should know as a consumer is that each cellular provider offers certain bands according to the area, and different phones enable different bands. So you have to make sure that your Oppo A9 (2020) supports the bands offered by your local mobile provider.
Here are the Oppo A9 (2020) 4G supported bands:
1, 3, 5, 8, 38, 40, 41;.
