An easy guide to 4G on BLU J9L


Wireless mobile technologies have developed enormously; one of the main developments is the rise of 4G technology. It’s a word that you’ve certainly faced in your daily life, but what is 4G? And is BLU J9L 4G capable? We will answer these and other questions related to BLU J9L 4G technology in the following article.

is the BLU J9L4G-capable phone?

The answer is yes. BLU J9L can use 4G network technology.

How do you tell whether BLU J9L is 4G-enabled or not?

It’s not rocket science to figure out whether your phone is 4G-enabled, but it’s still vital to know how to do it. Because you don’t want to be left over with a device lacking an essential technology nowadays.

You can check the information directly by googling the phone name or model number, and checking on the official site of the manufacturer or any other reliable site. If you are a classic person, you can check the manual or the device package.

Another easy method is checking the indication bar while the cellular data is on, if the BLU J9L 4G data is activated, then you will see a 4G or LTE symbol there. If it’s not mentioned then you must consider another method.

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 a 4G or an LTE option. If you don’t see either of them, then your smartphone isn’t 4G-capable.

How to switch to 4G on BLU J9L?

If you intend to activate your BLU J9L 4G network, then follow the instructions (it might differ a bit from the settings on your own device):

1- From Home screen, choose Apps.
2- Select Settings.
3- Select Network & Internet.
4- Select Mobile network.
5- Verify that Mobile data tile is turned on.
6- Select Preferred network type.
7- Choose 4G or LTE option.

Note: If you want to switch off 4G then choose a lower network type (3G for example) or tap Only 5G if it’s possible.

Definition of 4G on BLU J9L

It is the name used to describe fourth-generation wireless technology. It was introduced in 2008 by the International Telecommunication Union (ITU), an agency that defines the characteristics of 4G technology and previous technologies such as 2G and 3G. 4G is now the main wireless technology adopted by most mobile phones around the globe.

4G comes with speeds faster than its ascendant 3G. Thus, its emergence expanded the use of smartphones. At present, phone users can do almost the same activities that were only possible on computers before the emergence of 4G.

The best famous technology labeled 4G is LTE and the technologies developed from it , such as LTE-A. Usually, people confuse the two terms. For BLU J9L 4G to be adequate, it should be suitable for the protocols used by local telecommunication companies.

What distinguishes 4G on BLU J9L?

4G has all the features of 3G at more speed. It offers download speeds of around 14 Mbps up to speeds as high as 150 Mbps, five times faster than 3G. And it offers more than ten times the uploading data speeds of 3G, ranging from 8Mbps up to 50 Mbps.

Low latency is another advantage, it ranges from 60ms to 98 ms, Despite the fact that it’s only a few milliseconds lower than 3G, it is very important for some use cases such as video conferencing or online gaming, and other real-time interactions.

The rise of VoLTE standard added another feature to 4g technology which is the ability to make phone calls and browse the internet concurrently, with even better voice quality. All of these advantages are within your reach with BLU J9L 4G technology.

What are 4G bands? And which bands are available in the BLU J9L?

Before talking about 4G bands, you should know what the frequency is. Frequency is the repetition of an event, and it is quantified in radio communication by hertz (Hz).

Since radio waves are used for multiple applications besides 4G (television broadcasting and Aeronautics as examples), it is necessary to identify which frequencies must be used for what reason. 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 BLU J9L, is whether it supports the bands offered in your area by your local mobile operator or not. The BLU J9L4G-enabled bands are :
1, 2, 3, 4, 5, 7, 12, 17, 28;.
