Cellular technologies have evolved enormously, One of the main developments is the development of 4G technology. It’s a word that you’ve definitely faced in your daily life, but what is 4G? And is Oppo A9 4G enabled? We are going to answer these and other questions related to Oppo A9 4G technology in the following article.
is Oppo A9 4g eligible?
The answer is yes. Oppo A9 can use 4G network technology.
Checking the presence of 4G on Oppo A9
It’s not rocket science to find out whether your mobile phone is 4G capable, but it’s still essential to know how to do it. Because you don’t want to be left over with a phone lacking an essential technology nowadays.
You can check the information directly by googling the phone name or model number, and checking on the official website of the manufacturer or any other credible site. If you are a classic person, you can check the manual or the device package.
Another easy method is checking the status bar while the cellular data is on, if the Oppo A9 4G data is on, then you will notice a 4G or LTE symbol there. If it’s not present then you have to consider another way.
Another way is to check the settings: Go to 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 is 4G capable 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 A9?
If you need to activate your Oppo A9 4G network, then follow the instructions (it might differ slightly from the settings on your own device):
1- From Home screen, select Apps.
2- From the Apps tab, select 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- Select Preferred network type.
6- Choose 4G or LTE option.
Note: If you would like to turn off 4G then choose an inferior network type (such as 3G) or tap Only 5G if it’s possible.
Introduction to 4G technology on Oppo A9
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 A9?
4G was established to offer a more reliable internet connection on mobiles, and that’s clearly what it did. 4G technology offers much better 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 prominent criterion of 4G, is its low latency. We can promote latency as the time needed to transmit data or the delay between the action and the actual execution. Low latency means a better user experience. 4G has 100% better latency than 3G. The average 4G latency is 50 ms.
With the assistance of the VoLTE standard, 4G now offers better voice quality in phone calls and gives users the ability to surf the internet while making calls.
All of these advantages combined with the low cost of 4G expanded the use of Oppo A9 4G technology, to include better video conferencing, online gaming, and other real-time interactions.
Get to know 4G bands in your Oppo A9
Before talking about 4G bands, you should find out what is a frequency. Frequency is the repetition of an event, it is measured in radio communication by hertz (Hz).
Since radio waves are exploited for different purposes besides 4G (television broadcasting and Aeronautics as examples), it is necessary to identify which frequencies must be used for what use. 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 A9, is whether it supports the bands offered in your area by your local cellular operator or not. The Oppo A9 4G supported bands are :
1, 3, 4, 5, 8, 34, 38, 39, 40, 41;1, 3, 5, 7, 8, 20, 28, 38, 40, 41 – India;.
Oppo A9 4G Technology Frequently Asked Questions
How to know if 4G coverage is obtainable in my zone?
Before choosing your mobile provider you need to make sure it has 4G coverage in your zone. The easiest way to do so is by calling them and asking. Another way is to check their official website or any legit coverage map website.
Why I’m not connected to 4G although the settings are right?
If you own a phone that has 4G, and you don’t have a 4G connection, the reason might be that you are not on a 4G offer. Check your internet operator plans, or give them a call to activate it. If they don’t have a 4G package, then you might need to change your cellular provider.
What is 4G LTE?
4G LTE is a word used synonymously with 4G and LTE, which disturbs users. technically speaking, LTE is different than 4G. LTE stands for “Long Term Evolution”, a communication technology that evolved from 3G but is still not as fast as 4G. However, some companies promote it as 4G.
The difference between 4G and LTE became more unclear when LTE-A (LTE – Advanced) evolved. LTE-A has almost the same speed as 4G technology.
Are GSM and CDMA the same as 4G LTE?
Before the rise of 4G LTE, the most recognized standards were GSM (2G/3G) and CDMA (2G/3G). GSM stands for “Global System for Mobile communication” and as its name suggests, it’s a standard that is used on a global scale by most cellular providers.
CDMA on the other hand is an initialism for “Code-Division Multiple Access”, don’t get bothered by the name it’s just another standard. what you need to realize about it is that it’s not as widespread as GSM, and CDMA devices are often locked to a single carrier and can’t be shifted.
When considering buying either a GSM or CDMA device, you should consider the operator coverage in your area. Some operators support only GSM and others support only CDMA.
You have to also consider whether you need roaming or not, if you move a lot then CDMA could be a hurdle. Not to mention that the ideal option is a phone that is compatible with both.
4G technology didn’t support voice calls when it was first launched, so it was reliant on GSM and CDMA standards, but with the rise of VoLTE standard it became independent, so you don’t have to worry so much about GSM/CDMA.
Will 4G phones stop operating?
2G and 3G networks are being shut down around the world because 4G is everywhere and has all the previous generations’ features at better speeds. So it is a valid question to ask if the emergence of 5G networks will cause the shutdown of 4G.
The answer to that is: No. Your Oppo A9 4G technology will stay valuable for a few more years.
4G Networks will stay attainable for at least a decade or two, depending on the area and other factors. As things were for prior generations, 4G and 5G will coexist and work together, meaning phones supporting 5G will support 4G too as a fallback.
Is 4G still worth it currently?
Yes, it is. Although the high speeds of 5G, 4G is still acceptable and provides sufficient speed for most of the use cases. 4G network is larger than 5G, meaning you can use it almost all around the world. Another advantage of 4G is cost-effectiveness. Because 5G is still too expensive to be a better alternative.
4G is the fastest most deployed cellular network. Get to know it and see the instructions to enable it on Oppo A9.
