Mobile technologies have developed enormously; one of the main developments is the development of 4G technology. It’s a word that you’ve definitely faced in your daily life, but what is 4G? And is BLU F91 4G capable? We will answer these and other questions related to BLU F91 4G technology in the following article.
Does the BLU F91 have 4G?
Yes. 4G is one of BLU F91 inherent features.
How can I know whether BLU F91 is able to use 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 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 presence of a 4G or LTE sign in the indication bar.
Another way is to check the settings: Go to your settings and find 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 4G or LTE, then your smartphone doesn’t have the technology.
How to switch to 4G on BLU F91?
If you need to activate your BLU F91 4G network, then follow the instructions (it might change slightly from the settings on your own device):
1- From Home screen, select Apps.
2- Tap Settings.
3- Choose Mobile network.
4- Make sure the Mobile data is On.
5- Tap Preferred network type.
6- Select 4G or LTE option.
Note: If you would like to switch off 4G then choose an inferior network type (e.g. 3G) or tap Only 5G if it’s possible.
Get to know what 4G is on BLU F91
Mobile telecommunication technologies evolve by one generation nearly every 10 years. 4G is the fourth one, which was officially launched in 2009 in South Korea, and years after that it was provided in all populated areas. And by “they” we mean all phone network operators around the world.
They follow the International Telecommunication Union (ITU) standards. According to the ITU, a 4G labeled technology has fast internet speeds, achieving ten times the speed of 3G internet, and it also has low latency.
A lot of protocols were identified as 4G, such as: LTE, LTE+, and HSPA+.
What are the advantages of 4G on BLU F91?
4G was established to offer a more reliable internet connection on phones, and that’s clearly what it did. 4G technology offers much improved downloading and uploading speeds than 3G.
The average 3G speed is around 1.5 to 9 Mbit/s, while the average 4G internet speed is between 15 to 90 Mbit/s, it can reach as high as 900 Mbit/s.
Another essential criterion of 4G, is its low latency. We can promote latency as the time needed to transmit data or the delay between the action and the actual response. Lesser latency means a better user experience. 4G has 100% better latency than 3G. The average 4G latency is 50 ms.
With the aid of the VoLTE standard, 4G now presents better voice quality in phone calls and gives users the capability to surf the internet while making calls.
All of these advantages combined with the low cost of 4G widened the use of BLU F91 4G technology, to include better video conferencing, online gaming, and other real-time interactions.
Get to know 4G bands in the BLU F91
A 4G band is an interval of frequencies used by wireless service providers. Why this matters to you? It matters since each mobile network operator uses special bands according to the area. And not all mobiles support all 4G bands, so you should assure that your BLU F91 supports the bands provided in your area.
It’s hard to unite the bands worldwide, because each government uses different bands for different radio transactions aside from 4g (such as aeronautics and radio broadcasts). Despite this, the ITU segmented the world into 3 regions and bands for each region.
The BLU F914G-supported bands are:
2, 4, 5, 12, 13, 17, 25, 26, 41, 66, 71;.
