Internet on phones has faced a lot of changes, and different cellular technology generations, one of them is 4G technology. So what is 4G? Is HTC Desire 820s dual sim 4G capable? Let’s dive deeply into the subject, and figure out everything related to HTC Desire 820s dual sim 4G technology.
is the HTC Desire 820s dual sim4G-compatible phone?
Yes. HTC has embedded 4G in HTC Desire 820s dual sim phone.
How do you tell whether HTC Desire 820s dual sim is 4G-enabled or not?
It is necessary to check whether your device is 4G-enabled before buying it. The easiest option is to check your device specifications in your phone package, or in the manual. If you don’t possess the package or didn’t find the user guide, you can check your phone criteria on the official website of the manufacturer or any other dependable website.
The second option is verifying the status bar. If the HTC Desire 820s dual sim 4G data is running, you will see a 4G (or an LTE) sign at the top of the phone’s screen. Note that the absence of that sign doesn’t necessarily mean that your phone doesn’t support 4G.
Another way is to check the settings: open your settings and find network mode, usually as follows: Settings > Cellular (or Mobile Data) > Cellular Data Options (or Mobile Data Options). If your phone is 4G-capable 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 HTC Desire 820s dual sim?
If you intend to activate your HTC Desire 820s dual sim 4G network, then follow the instructions (it might change a bit from the settings on your own device):
1- From Home screen, choose Apps.
2- From the Apps tab, choose Settings.
3- Make sure the Mobile data tile is on.
4- Choose Mobile data.
5- Tap Network mode.
6- Choose 4G or LTE option.
Note 1:
When you have two SIM cards inserted on your phone, only one card can connect to the faster 4G LTE network. You can set which card you want to connect to the 4G LTE network from Dual network manager.
Note 2:
If you intend to turn off 4G then choose an inferior network type (3G for example).
Introduction to 4G technology on HTC Desire 820s dual sim
It is the term used to describe fourth-generation wireless technology. It was introduced in 2008 by the International Telecommunication Union (ITU), an agency that defines the specification of 4G technology and previous technologies such as 2G and 3G. 4G is now the higher wireless technology adopted by most mobile phones around the globe.
4G comes with speeds faster than its ancestor 3G. Thus, its emergence widened the use of smartphones. These days, phone users can do almost the same tasks that were only achieved on computers before the rise of 4G.
The best known protocol labeled 4G is LTE and the technologies developed from it (e.g. LTE-A). Usually, people confuse the two terms. For HTC Desire 820s dual sim 4G to be adequate, it should be suitable for the protocols used by local mobile network operators.
Advantages of 4G on HTC Desire 820s dual sim
4G was implemented to grant a more reliable internet connection on phones, and that’s truly what it did. 4G technology allows much enhanced downloading and uploading speeds than 3G.
The average 3G speed is around 1.5 to 9 Mbit/s, while the average 4G internet speed ranges 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 promote latency as the time needed to transfer data or the delay between the action and the actual execution. Lower latency means a better user experience. 4G has 100% better latency than 3G. The average 4G latency is 50 ms.
With the assistance of the VoLTE standard, 4G now allows better voice quality in phone calls and gives users the capability to browse the internet while making calls.
All of these advantages combined with the low cost of 4G augmented the use of HTC Desire 820s dual sim 4G technology, to include better video conferencing, online gaming, and other real-time interactions.
Get to know 4G bands in your HTC Desire 820s dual sim
4G and other cellular technologies use radio waves to transfer 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 (for example) are used at the international level.
What you should be aware of as a consumer is that each cellular provider permits certain bands according to the area, and different phones support different bands. So you should make sure that your HTC Desire 820s dual sim supports the bands provided by your local cellular operator.
Here are the HTC Desire 820s dual sim4G-enabled bands:
1, 3, 7, 8, 38, 39, 40, 41;.
