Wireless mobile technologies have developed enormously, One of the main developments is the rise of 4G technology. It’s a term that you’ve certainly faced in your daily life, but what is 4G? And is Oppo A9x 4G capable? We are going to answer these and other questions related to Oppo A9x 4G technology in the following article.
Does Oppo A9x have 4G?
Yes. The Oppo A9x is 4G capable
Get to know what is 4G on Oppo A9x
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 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+.
Advantages of 4G on Oppo A9x
4G was created to offer a more reliable internet connection on mobiles, and that’s truly what it did. 4G technology presents much stronger 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 promote latency as the time needed to transfer 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 aid of the VoLTE standard, 4G now provides better voice quality in phone calls and gives users the capability to browse the internet while making calls.
All of these advantages combined with the low cost of 4G expanded the use of Oppo A9x 4G technology, to include better video conferencing, online gaming, and other real-time interactions.
How can I know whether the Oppo A9x is able to use 4G or not?
Before buying your device you want to make sure that it supports 4G. you have so many ways to do it, we will list some of them here. The most obvious method is to check the specifications on the user guide or in the device’s box.
If you don’t have them or you are still lying on your couch trying to pick a suitable 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 A9x 4G data is on, then you will notice immediately a 4G icon on the top of the screen. You might see LTE or LTE+ instead of it. However, this way might be deceptive if you didn’t activate a 4G offer, or you are out of coverage.
Another way is to check the settings: Go to 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 4G option or LTE. If you don’t see 4G or LTE, then your smartphone isn’t 4G capable.
How to switch to 4G on Oppo A9x?
If you intend to activate your Oppo A9x 4G network, then follow the instructions (it might differ slightly from the settings on your own device):
1- From Home screen, choose Apps.
2- From the Apps tab, choose Settings.
3- Tap “SIM card & mobile data” or “Dual SIM & Cellular Network”.
4- Choose 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 prefer to turn off 4G then choose a lower network type (e.g. 3G) or tap Only 5G if it’s possible.
What are 4G bands? and which bands are supported on your Oppo A9x?
4G and other cellular networks use radio waves to communicate 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 known as bands. Band number 7 and band number 28 (as an example) are used at the world level.
What you should know as a consumer is that each carrier provides certain bands according to the area, and different phones enable different bands. So you have to make sure that your Oppo A9x supports the bands offered by your local carrier.
Here are the Oppo A9x 4G supported bands:
1, 3, 4, 5, 8, 34, 38, 39, 40, 41;.
