The 3G invention (short for a 3rd generation) is newer generation of wireless technology. in terms of speed and functionality, 3G is much better than previous 2G networks, that because vivo Y91i 3G devices offer higher speed bandwidth.
Does vivo Y91i Work on 3G Network Mode?
Please know that vivo Y91i has 3G technology.
Enabling 3G on vivo Y91i
To switch On/Off 3G on vivo Y91i apply these steps:
1) Choose Settings
2) Select Mobile Network
3) Tap Network Mode
4) Choose your network type.
Steps to Know That 3G Is Available on vivo Y91i
Because these two manners are working on both iOS and Android operating systems, we can count it as the major methods to identify if vivo Y91i 3G network is available or not.
Way-1
There is an icon on the top of the vivo Y91i screen indicates if 3G network is available or not.
Way-2
To see if your vivo Y91i has 3G network or not, you may use this way:
1) Dial *#06# on your mobile to get vivo Y91i IMEI number.
2) Go to www.imei.info, then enter your IMEI number and choose Check.
3) You’ll see a report. Look at the LTE section – it will display all the frequencies that are supported by your vivo Y91i. 3G service runs on the 2100MHz frequency, so if you see the number 2100, then your vivo Y91i is 3G compatible.

Note: LTE Option on mobile settings generally refers to 4G network.
Technical Information About vivo Y91i 3G Network
What is LTE?
Long-Term Evolution (LTE) is a standard for wireless broadband connections used for handheld devices and data terminals. LTE frequencies are:
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 networks.
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 handheld 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 word to refer to the capacity of a network.
