How to check the availability of 4G on Oppo A9 (2020)
There are various ways to check the presence of 4G in your Oppo A9 (2020), or any other phone. And presuming you’re not a techy person , I propose that you start by checking the phone container, network information is usually illustrated there. Or you can simply google your phone model name and figure out the information on the official website of the manufacturer.
If you have already bought the phone and inserted the SIM card, you can turn on the mobile data, if the phone connects to a 4G network you will see a 4G ot LTE sign up on the status bar.
Another way is to check the settings: open your settings and look for network mode, usually as follows: Settings > Cellular (or Mobile Data) > Cellular Data Options (or Mobile Data Options). If your phone has 4G you will find 4G option or LTE. If you don’t see either of them, then your smartphone isn’t 4G capable.

1- From Home screen, tap Apps.
2- From the Apps tab, choose 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- Tap Preferred network type.
6- Select 4G or LTE option.
Note: If you intend to switch off 4G then choose a lower network type (3G for example) or tap Only 5G if it’s possible.
Introduction to 4G technology on Oppo A9 (2020)
The International Telecommunication Union (ITU) is the entity that defined 4G in the first place, 4G is the fourth generation of wireless technologies. It comes just after 3G and preceding 5G.
4G has very high internet uploading/downloading speeds, ten times more than 3G, Which is enormous. It also has 50ms latency, much less than 3G.
4G is not just one technology, but a set of technologies compatible with ITU specifications. It includes LTE, LTE+, and HSPA+.
Feature of 4G technology on Oppo A9 (2020)
4G has all the functionalities of 3G at more speed. It offers download speeds of around 14 Mbps up to speeds as high as 150 Mbps, five times more than 3G. And it offers more than ten times the uploading data speeds of 3G, starting from 8Mbps up to 50 Mbps.
Low latency is another advantage, it ranges from 60ms to 98 ms, Even though it’s only a few milliseconds lower than 3G, it is very important for some use cases such as video conferencing or online gaming, and other real-time interactions.
The appearance of VoLTE standard added another feature to 4g network which is the ability to make phone calls and browse the internet in parallel, with even more suitable voice quality. All of these advantages are within your reach with Oppo A9 (2020) 4G technology.
What are 4G bands? and which bands are supported on your Oppo A9 (2020)?
Before talking about 4G bands, you should know what is a frequency. Frequency is the repetition of an event, it is quantified in radio communication by hertz (Hz).
Since radio waves are utilized for multiple applications besides 4G (radio broadcasting and satellite communication as examples), it is important to determine which frequencies must be used for what reason. Otherwise, radio waves will contradict, and it would be a mess.
Governments and ITU allocated each range of frequencies (called bands) to specific uses.
What you should consider as a user of Oppo A9 (2020), is whether it supports the bands present in your area by your local cellular provider or not. The Oppo A9 (2020) 4G enabled bands are :
1, 3, 5, 8, 38, 40, 41;.
