The 3G standard (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 BLU J9L 3G devices grant higher speed bandwidth.
Can BLU J9L Use 3G Networks?
Please note that 3G function is built-in on BLU J9L.
Switch ON 3G on BLU J9L
To switch On/Off 3G on BLU J9L apply this way:
1) Go to Settings
2) Choose Network & internet
3) Select Mobile network
4) Scroll to and hit Advanced
5) Scroll to and hit Preferred network type
6) Tap your network type.
Main Ways to Identify If BLU J9L 3G
Actually, there are many ways to identify if 3G function is working on BLU J9L or not. However, these two most used ways are working on both iOS and Android operating systems:
Way-1
On the top of your BLU J9L screen there will be a small icon refers to 3G.
Way-2
Apply these steps:
1) Dial *#06# on your mobile to know BLU J9L IMEI number.
2) Go to www.imei.info, type your IMEI number and choose Check.
3) You’ll get a report. Look at the LTE section – it will show all the frequencies that are supported by your phone. 3G service works on the 2100MHz frequency, so if you see the number 2100, then your BLU J9L is 3G compatible.
Please note that you can always check the phone’s user guide.
Note: LTE Option on mobile setting commonly refers to 4G connections.
Technical Information About BLU J9L 3G Network
What is LTE?
Long-Term Evolution (LTE) is a standard for wireless broadband communication used for handhelds devices and data terminals. Its frequencies as following:
3G connections: 900 MHz and 2100 MHz (band 1 and 39).
4G connections: 800 MHz (band 20), 1800 MHz and 2600 MHz (band 7 and 38).
5G connections: 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, defined by a lower and upper values of transmission capacity over network communication systems. However, in general we are using bandwidth term to refer to the capacity of a network.
