Wireless mobile technologies have improved enormously, One of the main developments is the emergence of 4G technology. It’s a word that you’ve absolutely faced in your daily life, but what is 4G? And is Oppo A55 4G enabled? We are going to answer these and other questions related to Oppo A55 4G technology in the following article.
Does Oppo A55 have 4G?
Yes. 4G technology is one of the Oppo A55 main features.
How to check the availability of 4G on Oppo A55
The safest option to check the existence of 4G network in any phone, is to check the official website, or the official packaging.
Another trusty option is turning on mobile data, and checking whether the phone connects to a 4G network or not, you’ll know that simply by the appearance of a 4G or LTE sign in the notification bar.
Another way is to check the settings: open 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 is 4G enabled you will find 4G option or LTE. If you don’t see either of them, then your smartphone isn’t 4G capable.
How to switch to 4G on Oppo A55?
If you would like to activate your Oppo A55 4G network, then follow the instructions (it might differ a bit from the settings on your own device):
1- From Home screen, select Apps.
2- From the Apps tab, choose Settings.
3- Choose “SIM card & mobile data” or “Dual SIM & Cellular Data”.
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 would like to turn off 4G then choose an inferior network type (e.g. 3G) or tap Only 5G if it’s possible.
Get to know what is 4G on Oppo A55
Mobile telecommunication technologies evolve by one generation almost in every 10 years. 4G is the fourth one, which officially instituted in 2009 in South Korea, and years after that it was made present in all inhabited areas. And by “they” we mean all phone carriers around the world.
They follow the International Telecommunication Union (ITU) guidelines. According to the ITU, a 4G marked technology has fast internet speeds, achieving ten times the speed of 3G internet. And it has also low latency.
A lot of protocols were identified 4G such as: LTE, LTE+, and HSPA+.
Feature of 4G technology on Oppo A55
4G was developed to provide a more reliable internet connection on phones, and that’s exactly what it did. 4G technology presents much better downloading and uploading speeds than 3G.
The average 3G speed is around 1.5 to 9 Mbit/s, while the average 4G internet speed ranges between 15 to 90 Mbit/s, it can reach as high as 900 Mbit/s.
Another significant criterion of 4G, is its low latency. We can present latency as the time needed to send data or the delay between the action and the actual response. Lower 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 widened the use of Oppo A55 4G technology, to include better video conferencing, online gaming, and other real-time interactions.
What are 4G bands? and which bands are available in the Oppo A55?
4G and other mobile networks use radio waves to communicate data. These waves have different lengths and frequencies. To avoid interference between signals, governments and the ITU regulated 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 international level.
What you should be aware of as a consumer is that each cellular operator grants certain bands according to the area, and different phones enable different bands. So you should make sure that your Oppo A55 supports the bands offered by your local carrier.
Here are the Oppo A55 4G supported bands:
1, 3, 5, 8, 38, 40, 41;.
