Cellular technologies have improved enormously; one of the main developments is the development of 4G technology. It’s a term that you’ve definitely faced in your daily life, but what is 4G? And is Nokia C21 4G enabled? We will answer these and other questions related to Nokia C21 4G technology in the following article.
is the Nokia C214G-eligible phone?
Yes. Nokia C21 is 4G compatible phone
How to check the availability of 4G on Nokia C21
Nowadays, it is necessary to purchase a 4G-capable phone, because most internet users require a good internet connection. To know whether the phone is 4G-capableor not, you can use multiple means.
An easy way when you hold the phone in your palm is just turning on the cellular data, if the Nokia C21 4G data is on, then you will find a symbol at the top of the screen, in the status bar. It might be 4G, 4G+, LTE, or LTE+ according to your carrier.
The absence of that icon means that you are not using 4G at that specific moment, and it doesn’t definitely mean that your phone doesn’t support 4G. And that takes us to the second option.
Check your phone specifications on the manual, or in the phone box. If you lose both of them, you can still check that on the official website (or any other credible website) using the device name or model number.
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 has 4G you will find a 4G or an LTE option. If you don’t see 4G or LTE, then your smartphone doesn’t have the technology.
How to switch to 4G on Nokia C21?
If you would like to enable your Nokia C21 4G network, then follow the instructions (it might change a bit from the settings on your own device):
1- From Home screen, tap Apps.
2- From the Apps tab, choose Settings.
3- Choose 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 want to switch off 4G then choose an inferior network type (e.g. 3G) or tap Only 5G if it’s possible.
Get to know what 4G is on Nokia C21
The International Telecommunication Union (ITU) is the entity that defined 4G in the first place, 4G is the fourth generation of wireless technologies. It comes just after 3G and preceding 5G.
4G has very high internet uploading/downloading speeds, ten times more than 3G, Which is enormous. It also has 50ms latency, much less than 3G.
4G is not just one technology, but a set of technologies compatible with ITU specifications. It includes LTE, LTE+, and HSPA+.
What are the advantages of 4G on Nokia C21?
4G has all the features of 3G at more speed. It offers download speeds of around 14 Mbps up to speeds as high as 150 Mbps, five times more than 3G. And it allows more than ten times the uploading data speeds of 3G, ranging from 8Mbps up to 50 Mbps.
Low latency is another advantage, it ranges from 60ms to 98 ms, Even though it’s only a bit lower than 3G, it is very significant for some use cases including video conferencing or online gaming, and other real-time interactions.
The emergence of VoLTE standard added another feature to 4g technology which is the ability to make phone calls and navigate the internet concurrently, with even more appropriate voice quality. All of these advantages are within your reach with Nokia C21 4G technology.
What are 4G bands? And which bands are supported on your Nokia C21?
4G and other cellular technologies use radio waves to communicate data. These waves have different lengths and frequencies. To avoid interference between signals, governments and the ITU decided which regions use which frequencies for 4G.
Each region has been designated certain frequency intervals called bands. Band number 7 and band number 28 are used all around the world.
What you should be aware of as a consumer is that each carrier permits specific bands according to the area, and different phones support different bands. So you should make sure that the Nokia C21 4G bands are the same as the bands provided by your local cellular operator.
