Mobile technologies have upgraded enormously; one of the main developments is the development of 4G technology. It’s a term that you’ve definitely encountered in your daily life, but what is 4G? And is BLU J7L 4G enabled? We will answer these and other questions related to BLU J7L 4G technology in the following article.
Does the BLU J7L have 4G?
Yes. BLU J7L supports 4G Network.
How can I know whether BLU J7L supports 4G or not?
The safest option to check the availability of 4G network in any phone, is to check the official website, or the official packaging.
Another trusty 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 appearance of a 4G or LTE sign in the indication bar.
Another way is to check the settings: Go to your settings and fetch 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 a 4G or an LTE option. If you don’t see 4G or LTE, then your smartphone isn’t 4G-enabled.
How to switch to 4G on BLU J7L?
If you would like to turn on your BLU J7L 4G network, then follow the instructions (it might change a bit from the settings on your own device):
1- From Home screen, tap Apps.
2- Choose Settings.
3- Choose Mobile network.
4- Verify that Mobile data is On.
5- Select Advanced.
6- Select Preferred network type.
7- Choose 4G or LTE option.
Note: If you would like to switch off 4G then choose a lower network type (such as 3G) or tap Only 5G if it’s possible.
Get to know what 4G is on BLU J7L
4G is the fourth generation of cellular communication technologies, it comes just after 3G and before 5G. Although 5G is considered the strongest technology existing in the world, 4G is still the fastest most deployed technology.
4G has fast uploading and downloading speeds, exceeding the previous 3G standards, and it also has decreased latency, allowing users to do much more things using their phones, things such as live conferencing.
To be more precise, 4G is a designation named by the International Telecommunication Union (ITU), and it is also a commercial term used by wireless carriers to exhibit a set of protocols used in their networks.
One of the most famous protocols is LTE and LTE-Advanced, So for BLU J7L 4G to be useful, it should be correspondent with the protocols used by local mobile network operators.
Why is 4G on the BLU J7L important?
4G is a developed technology that enabled a lot of possibilities for users. It has much more speed than 3G network. While the average speed of 3G is 3Mbit/s, 4G has an average of 10 Mbit/s.
Another benefit is the low latency. Despite the fact that the difference in Latency is tiny, 4G latency made HD web streaming achievable, and a much more suitable video games experience.
4G also has better quality voice calls, thanks to the VoLTE standard. It also enables you to check out the internet while making voice calls. All of these advantages are within your reach with BLU J7L 4G technology.
Get to know 4G bands in the BLU J7L
4G and other cellular networks use radio waves to transmit data. These waves have different lengths and frequencies. To prevent interference between signals, governments and the ITU decided which regions use which frequencies for 4G.
Each region has been allocated certain frequency intervals called bands. Band number 7 and band number 28 (for example) are used on a global scale.
What you should be aware of as a consumer is that each cellular operator permits specific bands according to the area, and different phones enable different bands. So you should make sure that your BLU J7L supports the bands provided by your local cellular provider.
Here are the BLU J7L4G-enabled bands:
1, 2, 3, 4, 5, 7, 12, 17, 28;.
