Wireless mobile technologies have upgraded enormously; one of the main developments is the emergence of 4G technology. It’s a term that you’ve definitely encountered in your daily life, but what is 4G? And is alcatel A7 4G enabled? We will answer these and other questions related to alcatel A7 4G technology in the following article.
is the alcatel A74G-eligible phone?
Yes. alcatel A7 is able to use 4G Network.
How to check the presence of 4G on alcatel A7
Before buying your phone, you want to make sure that it supports 4G. You have so many ways to do it, and we will list some of them here. The most obvious option is to check the criteria on the user guide or in the phone’s package.
If you don’t have them or you are still lying at home trying to find the perfect phone for you, you can do the same on the internet using the device name or model number.
If you would like to verify your current phone, just turn on the cellular data; if the alcatel A7 4G data is available, then you will immediately notice immediately see a 4G icon on the top of the screen. You might notice LTE or LTE+ instead of it. However, this method might be misleading if you are not on a 4G offer, or you are out of coverage.
Another way is to check the settings: open your settings and look for 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 either of them, then your smartphone isn’t 4G-capable.
How to switch to 4G on alcatel A7?
If you intend to turn on your alcatel A7 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- Choose Settings.
3- Verify that the Mobile data is on in Data usage.
4- Select “More…”.
5- Select Cellular/Mobile networks.
6- If your phone is dual SIM, then select the SIM card you want to manage.
7- Tap Preferred network mode.
8- Choose 4G or LTE option.
Note: If you intend to turn off 4G then choose an inferior network type (such as 3G).
Definition of 4G on alcatel A7
4G is the fourth generation of cellular communication technologies, it comes just after 3G and before 5G. Although 5G is the fastest technology available in the world, 4G is still the fastest most diffused technology.
4G has fast uploading and downloading speeds, overstepping the previous 3G standards, and it also has lower latency, allowing users to do much more activities using their mobiles, things such as live conferencing.
To be more accurate, 4G is a term assigned by the International Telecommunication Union (ITU), and it is also a commercial word used by mobile network operators to express a set of protocols used in their networks.
One of the most famous protocols is LTE and LTE-Advanced, So for alcatel A7 4G to be useful, it should be correspondent with the protocols used by local mobile network operators.
Why is 4G on the alcatel A7 important?
4G surpasses the old generation in terms of speed and latency. It grants 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, on the other hand, 4G has half of that, meaning 50 ms, which is better because latency is a time delay between the sender and the receiver. Although the difference is only 0.05 seconds, it presents 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 better voice calls and use the internet while talking on the cellphone. These advantages make alcatel A7 4G technology a great tool in your hand.
Get to know 4G bands in your alcatel A7
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 allocated certain frequency intervals called bands. Band number 7 and band number 28 (for example) are used all around the world.
What you should know as a consumer is that each cellular operator grants specific bands according to the area, and different phones enable different bands. So you should make sure that your alcatel A7 supports the bands offered by your local mobile operator.
Here are the alcatel A74G-supported bands:
1, 3, 7, 8, 20, 28;.
