In this article, we will discuss everything related to BLU R2 Plus 4G technology, starting with the question “is BLU R2 Plus 4G enabled” and defining the word itself.
is the BLU R2 Plus4G-compatible phone?
Yes. BLU R2 Plus supports 4G Network.

How can I know whether BLU R2 Plus supports 4G or not?
Before buying your phone, you want to make sure that it enables 4G. You have so many options to do it, and we will list some of them here. The most obvious way is to check the criteria on the user guide or in the phone’s box.
If you don’t have them or you are still lying on your couch trying to find the perfect device for you, you can do the same on the internet using the device name or model number.
If you would like to check your current phone, just turn on the mobile data; if the BLU R2 Plus 4G data is available, then you will immediately see immediately see a 4G icon on the top of the screen. You might see LTE or LTE+ instead of it. However, this way might be deceptive if you didn’t activate a 4G plan, or you are out of coverage.
Another way is to check the settings: open your settings and fetch 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 either of them, then your smartphone isn’t 4G-enabled.
How to switch to 4G on BLU R2 Plus?
If you intend to activate your BLU R2 Plus 4G network, then follow the instructions (it might change slightly from the settings on your own device):
1- From Home screen, tap Apps.
2- Tap Settings.
3- Make sure the the Mobile data switch is turned on.
4- Select “More…”.
5- Choose Mobile/Cellular networks.
6- Tap Preferred network type.
7- Select 4G or LTE option.
Note: If you prefer to switch off 4G then choose a lower network type (e.g. 3G) or tap Only 5G if it’s possible.

What 4G is on BLU R2 Plus?
Mobile telecommunication technologies evolve by one generation nearly every 10 years. 4G is the fourth one, which was officially instituted in 2009 in South Korea, and years after that it was made available in all populated areas. And by “they” we mean all phone network operators around the world.
They follow the International Telecommunication Union (ITU) guidelines. According to the ITU, a 4G titled technology has fast internet speeds, fulfilling ten times the speed of 3G internet, and it also has low latency.
A lot of protocols were referred as 4G, such as: LTE, LTE+, and HSPA+.
What are the advantages of 4G on BLU R2 Plus?
4G was developed to grant a more reliable internet connection on phones, and that’s truly what it did. 4G technology offers much higher 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 important criterion of 4G, is its low latency. We can present latency as the time needed to transfer data or the delay between the action and the actual response. Lower latency means a better user experience. 4G has 100% better latency than 3G. The average 4G latency is 50 ms.
With the help of the VoLTE standard, 4G now allows 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 R2 Plus 4G technology, to include better video conferencing, online gaming, and other real-time interactions.

What are 4G bands? And which bands are available in the BLU R2 Plus?
Before talking about 4G bands, you should find out what the frequency is. Frequency is the repetition of an event, and it is measured in radio communication by hertz (Hz).
Since radio waves are utilized for several applications besides 4G (radio broadcasting and satellite communication as examples), it is essential to determine which frequencies must be used for what purpose. Otherwise, radio waves will contradict, and it would be a mess.
Governments and ITU allocated each range of frequencies (called bands) to specific uses.
What you should consider as a user of BLU R2 Plus, is whether it supports the bands present in your area by your local cellular operator or not. The BLU R2 Plus4G-supported bands are :
1, 2, 3, 4, 7, 12, 17, 28;.
