4G was deployed years ago in most of the world and it is now considered the fastest most diffused cellular network. However, there is a lot of confusion surrounding it. And some people still don’t appreciate its significance.
What is 4g? Is it better than 3G? Is Oppo A33 (2020) 4G enabled? That’s what we are going to talk about in this article, besides everything related to Oppo A33 (2020) 4G technology.
Does Oppo A33 (2020) have 4G?
Yes. 4G is one of the Oppo A33 (2020) built-in features.
How can I know whether the Oppo A33 (2020) supports 4G or not?
Nowadays, it is necessary to purchase a 4G-enabled device, since most internet uses require a good internet connection. To know whether the phone is 4G capable you can use multiple ways.
An easy method when you hold the phone in your palm is just switching on the cellular data, if the Oppo A33 (2020) 4G data is on, then you will see a sign at the top of the display, in the indication bar. It might be 4G, 4G+, LTE, or LTE+ according to your carrier.
The absence of that icon means that you are not using 4G at that particular moment, and it doesn’t mean certainly that your device doesn’t enable 4G. And that takes us to the second method.
Check your phone specifications on the manual, or in the phone package. If you don’t have any of them you can still check that on the official website (or any other trustworthy website) using the device name or model number.
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 has 4G you will find 4G option or LTE. If you don’t see either of them, then your smartphone doesn’t have the technology.
How to switch to 4G on Oppo A33 (2020)?
If you would like to switch on your Oppo A33 (2020) 4G network, then follow the instructions (it might vary slightly from the settings on your own device):
1- From Home screen, select Apps.
2- From the Apps tab, select Settings.
3- Select Mobile Networks.
4- Select Network Mode.
5- Choose 4G or LTE option.
Note: If you need to turn off 4G then choose a lower network type (such as 3G) or tap Only 5G if it’s possible.
Introduction to 4G technology on Oppo A33 (2020)
Mobile telecommunication technologies evolve by one generation nearly every 10 years. 4G is the fourth one, which officially unleashed in 2009 in South Korea, and years after that it was made present in all inhabited areas. And by “they” we mean all phone carriers around the globe.
They follow the International Telecommunication Union (ITU) standards. According to the ITU, a 4G labeled technology has fast internet speeds, fulfilling ten times the speed of 3G internet. And it has also low latency.
A lot of protocols were described 4G such as: LTE, LTE+, and HSPA+.
What are the advantages of 4G on Oppo A33 (2020)?
4G is an evolved technology that enabled a lot of potential for users. It has much more speed than 3G technology, while the average speed of 3G is 3Mbit/s, 4G offers an average of 10 Mbit/s.
Another benefit is the low latency. Despite the fact that the difference in Latency is a little, 4G latency made HD web streaming practicable, and a much more developed video games experience.
4G has also clearer voice calls, thanks to the VoLTE standard. It also allows you to browse the internet while making voice calls. All of these advantages are within your reach with Oppo A33 (2020) 4G technology.
What are 4G bands? and which bands are available in your Oppo A33 (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 numerous applications besides 4G (television broadcasting and satellite communication as examples), it is necessary to determine which frequencies must be used for what purpose. Otherwise, radio waves will contradict, and it would be a mess.
Governments and ITU designated each range of frequencies (called bands) to certain uses.
What you should consider as a user of Oppo A33 (2020), is whether it supports the bands present in your area by your local mobile operator or not. The Oppo A33 (2020) 4G enabled bands are :
1, 3, 5, 7, 8, 38, 40, 41;.
