4G is the fourth generation of mobile telecommunication. It was first released in 2009 in South Korea, and it was deployed after that all around the world until it became the fastest and most used network in mobiles.

The provider of 4G network specifications is the International Telecommunication Union (ITU), it has also identified 5G, and 3G specifications before that. The ITU specifies what internet speeds and what are latency limits acceptable to call a network protocol a 4G.

Many protocols passed the test and qualified as 4G, the most important are LTE, LTE+, and HSPA+.  

What are the advantages of 4G on Oppo A57?

4G was established to deliver a more reliable internet connection on mobiles, and that’s truly what it did. 4G technology serves much improved 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 important criterion of 4G, is its low latency. We can present latency as the time needed to transmit 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 help 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 increased the use of Oppo A57 4G technology, to include better video conferencing, online gaming, and other real-time interactions.

How can I know whether the Oppo A57 supports 4G or not?

Nowadays, it is necessary to purchase a 4G-capable device, because most internet users need a good internet connection. To know whether the phone is 4G capable you can use multiple means.

An easy method when you pick the device in your palm is just switching on the mobile data, if the Oppo A57 4G data is activated, then you will see a sign 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 icon 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 credible website) using the device name or model number.

Another way is to check the settings: open your settings and find 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 a 4G option or LTE. If you don’t see either of them, then your smartphone isn’t 4G enabled.

How to switch to 4G on Oppo A57?

If you intend to turn on your Oppo A57 4G network, then follow the instructions (it might change slightly from the settings on your own device):

1- From the Home screen, tap Apps.
2- From the Apps tab, tap Settings.
3- Tap the Mobile network.
4- Choose the sim card you want to manage (the one used for data if your device is dual sim).
5- Select the Preferred network type.
6- Select the 4G or LTE option.

Note: If you would like to switch off 4G then choose an inferior network type (such as 3G) or tap Only 5G if it’s possible.

Get to know 4G bands in your Oppo A57

A 4G band is an interval of frequencies used by mobile network operators. Why this matters to you? It matters because each phone carrier uses different bands corresponding to the area. And not all phones support all 4G bands, so you should assure that your Oppo A57 supports the bands provided in your area.

It’s hard to formalize the bands globally because each government uses different bands for different radio transactions aside from 4g (such as aeronautics and radio broadcasts). Despite this, the ITU divided the world into 3 regions and bands for each region.

The Oppo A57 4 G-enabled bands are:
1, 3, 5, 7, 8, 28, 34, 38, 39, 40, 41;.
