Wireless mobile technologies have progressed enormously, One of the main developments is the development of 4G technology. It’s a term that you’ve absolutely faced in your daily life, but what is 4G? And is Oppo A71 (2018) 4G capable? We are going to answer these and other questions related to Oppo A71 (2018) 4G technology in the following article.
Does Oppo A71 (2018) have 4G?
Yes. The Oppo A71 (2018) is 4G compatible phone
What is 4G on Oppo A71 (2018)?
It is the name used to describe the fourth generation wireless technology. It was introduced in 2008 by the International Telecommunication Union (ITU), an organization that defines the characteristics of the 4G technology, and previous technologies such as 2G and 3G. 4G now is the strongest cellular technology adopted by most mobile phones around the globe.
4G comes with speeds faster than its predecessor 3G, thus its emergence extended the use of phones. Nowadays, phone users can do almost the same tasks that were only achieved on computers before the appearance of 4G.
The most known protocol labeled 4G is LTE and the technologies developed from it (LTE-A for example). Usually, people confuse the two terms. For Oppo A71 (2018) 4G to be adequate, it should be suitable for the protocols used by the local mobile network operators.
Advantages of 4G on Oppo A71 (2018)
4G outruns the preceding generation in terms of speed and latency. It grants 10 times higher downloading and uploading internet speeds. The average 3G speed is around 5 Mbit/s, and the average 4G speed is about 50 Mbit/s.
In terms of latency, 3G grants a 100 ms latency, while 4G has half of that, meaning 50 ms, which is better because latency is a time delay between the sender and the receiver. Although the difference is only 0.05 seconds, it presents an enormous advantage in live interactions, like gaming experiences and live broadcasting.
VoLTE is a protocol that gave 4G a boost. It allows users to make better voice calls and use the internet while talking on mobile. These advantages make Oppo A71 (2018) 4G technology a great tool in your pocket.
How can I know whether the Oppo A71 (2018) is able to use 4G or not?
Nowadays, it is necessary to buy a 4G-capable device, because most internet uses need a good internet connection. To know whether the phone is 4G capable you can use multiple means.
An easy method when you hold the device in your palm is just switching on the mobile data, if the Oppo A71 (2018) 4G data is activated, then you will see an icon at the top of the screen, in the indication bar. It might be 4G, 4G+, LTE, or LTE+ according to your carrier.
The absence of that symbol means that you are not using 4G at that specific moment, and it doesn’t signify certainly that your phone doesn’t enable 4G. And that takes us to the second way.
Check your phone specifications on the manual, or in the device package. If you don’t have any of them you can still check that on the official site (or any other trustworthy website) using the device name or model number.
Another way is to check the settings: Go to 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 supports 4G you will find 4G option or LTE. If you don’t see 4G or LTE, then your smartphone doesn’t support the technology.
How to switch to 4G on Oppo A71 (2018)?
If you need to activate your Oppo A71 (2018) 4G network, then follow the instructions (it might vary slightly from the settings on your own device):
1- From Home screen, tap Apps.
2- From the Apps tab, select Settings.
3- Tap Mobile Networks.
4- Select Network Mode.
5- Choose 4G or LTE option.
Note: If you need to switch off 4G then choose a lower network type (such as 3G) or tap Only 5G if it’s possible.
What are 4G bands? and which bands are supported on your Oppo A71 (2018)?
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 in the whole world.
What you should know as a consumer is that each mobile operator grants certain bands according to the area, and different phones enable different bands. So you have to make sure that your Oppo A71 (2018) supports the bands offered by your local cellular operator.
Here are the Oppo A71 (2018) 4G supported bands:
1, 3, 5, 7, 8, 38, 40, 41;1, 3, 5, 8, 38, 40, 41 – India;.
