Internet on mobiles has experienced a lot of changes, and different wireless technology generations, one of them is 4G technology. So what is 4G? Is Oppo F15 4G enabled? Let’s dive deeply into the subject, and find out everything related to Oppo F15 4G technology.
Does Oppo F15 have 4G?
Yes. The Oppo F15 supports 4G Network.
Get to know what is 4G on Oppo F15
4G is the fourth generation of cellular communication technologies, it comes just after 3G and before 5G. Although 5G is considered the highest technology present in the market, 4G is still the fastest most spread technology.
4G has fast uploading and downloading speeds, overtaking the previous 3G technology, and it also has better latency, allowing users to do much more things using their phones, things such as live conferencing.
To be more specific, 4G is a designation assigned by the International Telecommunication Union (ITU), and it is also a commercial term used by wireless carriers to promote a set of protocols used in their networks.
One of the most famous protocols is LTE and LTE-Advanced, So for Oppo F15 4G to be useful, it should be compatible with the protocols used by the local mobile network operators.
Advantages of 4G on Oppo F15
4G surpasses the antecedent generation in terms of speed and latency. It offers 10 times higher downloading and uploading internet speeds. The average 3G speed is around 5 Mbit/s, and the average 4G speed is about 50 Mbit/s.
In terms of latency, 3G offers a 100 ms latency, while 4G has half of that, meaning 50 ms, which is better because latency is a time delay between the sender and the receiver. Although the difference is only 0.05 seconds, it presents a vast advantage in live interactions, like gaming experiences and live broadcasting.
VoLTE is a protocol that gave 4G a boost. It allows users to make better voice calls and browse the internet while talking on cellphone. These advantages make Oppo F15 4G technology a great tool in your pocket.
How can I know whether the Oppo F15 supports 4G or not?
It is necessary to check whether your device supports 4G before buying it. There are different methods to do so, The easiest option is to read your phone specifications in your phone package, or in the manual. If you don’t have the package or lost the manual, you can check your phone specifications on the official website of the manufacturer or any other reliable website.
The second option is verifying the status bar. If the Oppo F15 4G data is running, you will notice a 4G (or LTE) sign at the top of the phone’s screen. Note that the absence of that symbol doesn’t mean necessarily that your phone doesn’t support 4G.
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 has 4G you will find 4G option or LTE. If you don’t see 4G or LTE, then your smartphone isn’t 4G enabled.
How to switch to 4G on Oppo F15?
If you intend to switch on your Oppo F15 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, tap Settings.
3- Select “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 want to turn off 4G then choose an inferior network type (such as 3G) or tap Only 5G if it’s possible.
What are 4G bands? and which bands are available in the Oppo F15?
Before talking about 4G bands, you should know what is a frequency. Frequency is the repetition of an event, it is quantified in radio communication by hertz (Hz).
Since radio waves are utilized for several reasons besides 4G (television broadcasting and satellite communication as examples), it is necessary to determine which frequencies must be used for what reason. Otherwise, radio waves will contradict, and it would be a mess.
Governments and ITU allocated each range of frequencies (called bands) to certain uses.
What you should consider as a user of Oppo F15, is whether it supports the bands present in your area by your local cellular provider or not. The Oppo F15 4G enabled bands are :
1, 3, 5, 8, 38, 40, 41;.
