Wireless mobile technologies have improved enormously; one of the main developments is the emergence of 4G technology. It’s a term that you’ve surely faced in your daily life, but what is 4G? And is Nokia G21 4G enabled? We will answer these and other questions related to Nokia G21 4G technology in the following article.
is the Nokia G214G-eligible phone?
The answer is yes. Nokia G21 is able to use 4G cellular technology.
How to check the existence of 4G on Nokia G21
It is important to check whether your phone has 4G before buying it. The easiest method is to verify your phone specifications in your phone box, or in the manual. If you don’t possess the package or didn’t find the manual, you can check your phone criteria on the official website of the manufacturer or any other credible website.
The second option is verifying the indication bar. If the Nokia G21 4G data is turned on, you will notice a 4G (or an LTE) icon at the top of the phone’s display. Note that the absence of that symbol doesn’t necessarily mean that your phone doesn’t support 4G.
Another way is to check the settings: open your settings and search for network mode, usually as follows: Settings > Cellular (or Mobile Data) > Cellular Data Options (or Mobile Data Options). If your phone is 4G-enabled you will find a 4G or an LTE option. If you don’t see 4G or LTE, then your smartphone isn’t 4G-enabled.
How to switch to 4G on Nokia G21?
If you need to turn on your Nokia G21 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, choose Settings.
3- Tap Network and Internet.
4- Select Mobile network.
5- Verify that the Mobile data is on.
6- Select Preferred network type.
7- Select 4G or LTE option.
Note: If you intend to turn off 4G then choose a lower network type (3G for example) or tap Only 5G if it’s possible.
What 4G is on Nokia G21?
4G is the fourth generation of wireless technologies, it comes just after 3G and before 5G. Although 5G is considered the fastest technology present in the market, 4G is still the fastest most diffused technology.
4G has fast uploading and downloading speeds, overstepping the previous 3G standards, and it also comes lower latency, allowing users to do much more activities using their mobiles, things such as live conferencing.
To be more accurate, 4G is a designation named by the International Telecommunication Union (ITU), and it is also a commercial term used by wireless service providers to exhibit a set of protocols used in their networks.
One of the most famous protocols is LTE and LTE-Advanced, So for Nokia G21 4G to be useful, it should be suitable with the protocols used by local telecommunication companies.
Why is 4G on the Nokia G21 important?
4G bypasses the old generation in terms of speed and latency. It provides 10 times better 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, while 4G has half of that, meaning 50 ms, which is preferable since latency is a time delay between the sender and the receiver. Although the difference is only 0.05 seconds, it translates to a vast advantage in live interactions, such as gaming experiences and live broadcasting.
VoLTE is a standard that gave 4G a boost. It allows users to make improved voice calls and browse the internet while speaking on the mobile. These advantages make Nokia G21 4G technology a great tool in your hand.
What are 4G bands? And which bands are available in the Nokia G21?
Before talking about 4G bands, you should find out what the frequency is. Frequency is the repetition of an event, and it is quantified in radio communication by hertz (Hz).
Since radio waves are utilized for several applications besides 4G (radio broadcasting and Aeronautics as examples), it is important to decide 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 certain uses.
What you should consider as a user of Nokia G21, is whether it supports the bands provided in your area by your local cellular operator or not. The Nokia G214G-enabled bands are :
1, 3, 5, 7, 8, 20, 28, 38, 40, 41 – International;1, 2, 3, 4, 5, 7, 8, 12, 17, 28, 40, 66 – LATAM;.
