Cellular technologies have advanced enormously; one of the main developments is the rise of 4G technology. It’s a term that you’ve certainly encountered in your daily life, but what is 4G? And is LG Optimus LTE SU640 4G capable? We will answer these and other questions related to LG Optimus LTE SU640 4G technology in the following article.
Does the LG Optimus LTE SU640 have 4G?
Yes. LG Optimus LTE SU640 is compatible with 4G technology.
How can I know whether LG Optimus LTE SU640 is able to use 4G or not?
There are different ways to check the affordability of 4G in your LG Optimus LTE SU640, or any other phone. And assuming you’re not a techy person , I suggest that you start by checking the phone package, network information is usually illustrated there. Or you can simply google your phone model name and find out the information on the official website of the manufacturer.
If you have already bought the phone and inserted the SIM card, you can turn on the mobile data, if the phone connects to a 4G network you will notice a 4G ot LTE sign up on the notification bar.
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 4G or LTE, then your smartphone doesn’t support the standard.
How to switch to 4G on LG Optimus LTE SU640?
If you would like to switch on your LG Optimus LTE SU640 4G network, then follow the instructions (it might change a bit from the settings on your own device):
1- From Home screen, select Apps.
2- From the Apps tab, select Settings.
3- Choose “More…”.
4- Tap Mobile networks.
5- Make sure to switch on Data.
6- Select Network type and strength (or network mode).
7- Choose 4G or LTE option.
Note: If you want to switch off 4G then choose an inferior network type (3G for example).
What 4G is on LG Optimus LTE SU640?
4G is the short name for fourth-generation wireless. This means the fourth generation of cellular communication technology. It was developed after 3G and it is ahead of 5G. It was first officially released to the public in 2009, and it was made available years after all around the world.
Although 4G network is not as fast as 5G, it is way faster than 3G. Currently, it is the highest technology adopted by most mobile phones all over the world.
LG Optimus LTE SU640 4G technology and 4G in other devices changed how we use phones, it allowed users to stream HD videos (as an example). The high speed of 4G network turned smartphones into computers since smartphone users can do anything possible on computers.
LTE (stands for Long Term Evolution) and LTE+ are the best popular 4G standards, and usually, people are confused between them.
Why is 4G on the LG Optimus LTE SU640 important?
4G outruns the old generation in terms of speed and latency. It has 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 grants a 100 ms latency, on the other hand, 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 permits users to have better voice calls and use the internet while talking on the mobile. These advantages make LG Optimus LTE SU640 4G technology a great tool in your pocket.
Get to know 4G bands in the LG Optimus LTE SU640
4G and other mobile technologies use radio waves to communicate data. These waves have different lengths and frequencies. To avoid interference between signals, governments and the ITU regulated which regions use which frequencies for 4G.
Each region has been designated certain frequency intervals called bands. Band number 7 and band number 28 (as an example) are used all over the world.
What you should be aware of as a consumer is that each mobile provider permits specific bands according to the area, and different phones support different bands. So you have to make sure that your LG Optimus LTE SU640 supports the bands provided by your local cellular provider.
Here are the LG Optimus LTE SU6404G-supported bands:
