Cellular technologies have advanced enormously; one of the main developments is the rise of 4G technology. It’s a word that you’ve surely faced in your daily life, but what is 4G? And is BLU J5L 4G capable? We will answer these and other questions related to BLU J5L 4G technology in the following article.
is the BLU J5L4G-eligible phone?
Yes. BLU has included 4G in BLU J5L phone.

How to check the existence of 4G on BLU J5L
It is essential to check whether your phone has 4G before purchasing it. The easiest option is to read your device specifications in your phone package, or in the manual. If you don’t have the box or lost the user guide, you can check your phone criteria on the official website of the manufacturer or any other dependable website.
The second method is verifying the status bar. If the BLU J5L 4G data is running, you will notice a 4G (or an LTE) sign at the top of the device’s screen. Note that the absence of that icon doesn’t necessarily mean that your phone doesn’t support 4G.
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 supports 4G you will find a 4G or an LTE option. If you don’t see either of them, then your smartphone doesn’t have the technology.

How to switch to 4G on BLU J5L?
If you need to activate your BLU J5L 4G network, then follow the instructions (it might vary slightly from the settings on your own device):
1- From Home screen, choose Apps.
2- Tap Settings.
3- Select Mobile network.
4- Make sure the Mobile data is On.
5- Tap Advanced.
6- Tap Preferred network type.
7- Select 4G or LTE option.
Note: If you need to turn off 4G then choose an inferior network type (3G for example) or tap Only 5G if it’s possible.
What 4G is on BLU J5L?
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 are the advantages of 4G on BLU J5L?
4G has all the attributes of 3G at more speed. It provides download speeds of around 14 Mbps up to speeds as high as 150 Mbps, five times more than 3G. And it allows more than ten times the uploading data speeds of 3G, starting from 8Mbps up to 50 Mbps.
Low latency is another feature, it ranges from 60ms to 98 ms, Even though it’s only a bit lower than 3G, it is very vital for some use cases like video conferencing or online gaming, and other live interactions.
The appearance of VoLTE standard added another advantage to 4g network which is the ability to make phone calls and navigate the internet simultaneously, with even more suitable voice quality. All of these advantages are within your reach with BLU J5L 4G technology.

What are 4G bands? And which bands are supported on your BLU J5L?
Before talking about 4G bands, you should find out what the frequency is. Frequency is the repetition of an event, and it is measured in radio communication by hertz (Hz).
Since radio waves are utilized for different purposes besides 4G (radio broadcasting and satellite communication as examples), it is vital to determine which frequencies must be used for what purpose. Otherwise, radio waves will contradict, and it would be a mess.
Governments and ITU allocated each range of frequencies (called bands) to specific uses.
What you should consider as a user of BLU J5L, is whether it supports the bands present in your area by your local mobile provider or not. The BLU J5L4G-supported bands are :
1, 2, 3, 4, 5, 7, 12, 17, 28;.
