In addition to voice communications, third-generation cellular technology will provide 3G LG K40S with fairly high speed wireless connections for a range of data formats, including multimedia, sound tracks, and video. However, we have to realize that 2G networks can also be used by 3G mobile phones.
LG K40S 3G Availability
Please know that 3G facility is available on LG K40S.
Switching ON/OFF 3G on LG K40S
To switch On/Off 3G on LG K40S follow these steps:
1) Choose Settings,
2) Select Network,
3) Scroll to and choose Mobile networks,
4) Hit Network mode,
5) Hit GSM / WCDMA auto to switch On 3G.
Easy Way to Know if Your LG K40S Supports 3G
Because these two manners are working on both iOS and Android operating systems, we can consider it as the main ways to identify if LG K40S 3G network is available or not.
Way-1
There is an icon on the top of the LG K40S refers if 3G network is available or not.
Way-2
To identify if your LG K40S supports 3G network or not, you can use this method:
1) Dial *#06# on your phone to identify LG K40S IMEI number.
2) Go to www.imei.info, write your IMEI number and select Check.
3) You’ll see a report. Look at the LTE section – it will display all the frequencies that are supported by your LG K40S. 3G service works on the 2100MHz frequency, so if you see the number 2100, then your LG K40S is 3G compatible.
Please note that you can always check the phone’s user guide.
Note: LTE Option on mobile settings commonly refers to 4G network.
Technical Information About LG K40S 3G Network
LTE Meaning:
Long-Term Evolution (LTE) is a standard for wireless broadband communication used for handhelds devices and data terminals. Its frequencies as following:
3G networks: 900 MHz and 2100 MHz (band 1 and 39).
4G networks: 800 MHz (band 20), 1800 MHz and 2600 MHz (band 7 and 38).
5G networks: 700 MHz (band 28) and 3500 MHz (band 78).
Note: LTE Option in mobiles settings generally refers to 4G connections.
Knowing More About MHz:
MHz (Megahertz) is a unit of frequency equal to one million cycles per second. It is used to measure the transmission speed of electronic devices, including cellular phone communications.
Understanding Band:
The band is an interval in the frequency domain, restricted by a lower and upper values of transmission capacity over network communication systems. However, broadly we are using bandwidth expression to refer to the capacity of a network.
