In this article, we will discuss everything related to Oppo A55 4G technology, starting with the question “is Oppo A55 4G enabled” and defining the word itself.
Does Oppo A55 have 4G?
Yes. Oppo integrated 4G in their Oppo A55 phone.
How do you tell whether the Oppo A55 is 4G capable or not?
The most reliable option to check the availability of 4G network in any phone, is checking the official website, or the official packaging.
Another reliable option is switching on mobile data, and checking whether the phone connects to a 4G network or not, you’ll know that simply by the emergence of a 4G or LTE sign in the indication bar.
Another way is to check the settings: open 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 either of them, then your smartphone doesn’t support the standard.
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 vary a bit from the settings on your own device):
1- From Home screen, select Apps.
2- From the Apps tab, tap Settings.
3- Choose “SIM card & mobile data” or “Dual SIM & Cellular Data”.
4- Select the sim card you want to manage (the one used for data if your device is dual sim).
5- Tap Preferred network type.
6- Choose 4G or LTE option.
Note: If you intend to switch off 4G then choose an inferior network type (3G for example) or tap Only 5G if it’s possible.
Get to know what is 4G on Oppo A55
4G is the fourth generation of wireless technologies, it comes just after 3G and before 5G. Although 5G is considered the strongest technology present in the market, 4G is still the fastest most diffused technology.
4G has fast uploading and downloading speeds, overtaking the previous 3G standards, and it also came with better latency, allowing users to try much more things using their phones, things such as live conferencing.
To be more accurate, 4G is a designation assigned by the International Telecommunication Union (ITU), and it is also a commercial term used by wireless service providers to express a set of protocols used in their networks.
One of the most famous protocols is LTE and LTE-Advanced, So for Oppo A55 4G to be useful, it should be compatible with the protocols used by the local mobile network operators.
Why 4G on Oppo A55 is important?
4G was implemented to grant a more reliable internet connection on phones, and that’s clearly what it did. 4G technology presents much enhanced 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 simplify latency and say it’s the time needed to transfer data or the delay between the action and the actual response. Reduced 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 allows 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 augmented 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 your Oppo A55?
4G and other cellular networks use radio waves to transfer 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 designated certain frequency intervals known as bands. Band number 7 and band number 28 (as an example) are used in the whole world.
What you should know as a consumer is that each mobile operator grants specific bands according to the area, and different phones enable different bands. So you have to make sure that your Oppo A55 supports the bands provided by your local mobile provider.
Here are the Oppo A55 4G supported bands:
1, 3, 5, 8, 38, 40, 41;.
