Cellular technologies have advanced enormously, One of the main developments is the rise of 4G technology. It’s a term that you’ve surely encountered in your daily life, but what is 4G? And is Oppo A15 4G capable? We are going to answer these and other questions related to Oppo A15 4G technology in the following article.
Does Oppo A15 have 4G?
Yes. The Oppo A15 is able to use 4G Network.
How to check the existence of 4G on Oppo A15
Before buying your phone you want to make sure that it enables 4G. you have so many methods to do it, we will list some of them here. The most obvious option is to check the criteria on the user guide or in the device’s box.
If you lost them or you are still lying on your couch trying to choose the perfect phone for you, you can do the same on the internet using the device name or model number.
If you want to verify your current phone, just turn on the mobile data, if the Oppo A15 4G data is available, then you will see immediately a 4G sign on the top of the display. You might see LTE or LTE+ instead of it. However, this method might be deceptive 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 find 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 standard.
How to switch to 4G on Oppo A15?
If you want to activate your Oppo A15 4G network, then follow the instructions (it might change slightly from the settings on your own device):
1- From Home screen, tap Apps.
2- From the Apps tab, choose Settings.
3- Tap Mobile Networks.
4- Select Network Mode.
5- Select 4G or LTE option.
Note: If you want to switch off 4G then choose an inferior network type (such as 3G) or tap Only 5G if it’s possible.
Get to know what is 4G on Oppo A15
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+.
What distinguishes 4G on Oppo A15?
4G was created to deliver a more reliable internet connection on mobiles, and that’s exactly what it did. 4G technology provides much higher 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 achieve as high as 900 Mbit/s.
Another vital 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 execution. Reduced latency means a better user experience. 4G has 100% better latency than 3G. 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 ability to navigate the internet while making calls.
All of these advantages combined with the low cost of 4G increased the use of Oppo A15 4G technology, to include better video conferencing, online gaming, and other real-time interactions.
What are 4G bands? and which bands are supported on your Oppo A15?
4G and other cellular technologies 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 designated certain frequency intervals known as bands. Band number 7 and band number 28 (for example) are used in the whole world.
What you should know as a consumer is that each cellular provider offers specific bands according to the area, and different phones support different bands. So you have to make sure that your Oppo A15 supports the bands provided by your local cellular operator.
Here are the Oppo A15 4G enabled bands:
1, 3, 5, 8, 38, 40, 41;.
