In this article, we will discuss everything related to Microsoft Lumia 640 XL LTE Dual SIM 4G technology, starting with the question “is Microsoft Lumia 640 XL LTE Dual SIM 4G enabled” and defining the word itself.
Does the Microsoft Lumia 640 XL LTE Dual SIM have 4G?
Yes. Microsoft Lumia 640 XL LTE Dual SIM is 4G compatible phone
How can I know whether Microsoft Lumia 640 XL LTE Dual SIM is able to use 4G or not?
The safest option to check the availability of 4G network in any phone, is to check the official website, or the official packaging.
Another reliable option is switching on mobile data, and checking whether the phone connects to a 4G network or not, you’ll know that simply by the presence of a 4G or LTE sign in the notification bar.
How to switch to 4G on Microsoft Lumia 640 XL LTE Dual SIM?
If you intend to switch on your Microsoft Lumia 640 XL LTE Dual SIM 4G network, then follow the instructions (it might vary a bit from the settings on your own device):
1- From Home screen, tap Apps.
2- Choose ALL SETTINGS.
3- Choose mobile+SIM.
4- Make sure the Data connection is on.
5- Select Highest connection speed.
6- Select 4G or LTE option.
Note: If you need to turn off 4G then choose a lower network type (such as 3G).
Introduction to 4G technology on Microsoft Lumia 640 XL LTE Dual SIM
4G describes mobile network technology. It was determined by the ITU (International Telecommunication Union) and deployed by wireless service providers. To call a system 4G it should meet some specifications.
The ‘G’ in 4G is the first letter of the word generation, and 4 is the order of the generation, just after 3G and preceding 5G. 4G networks have to deliver internet speeds much faster than 3G, they also grant low latency, which is necessary for some uses such as gaming services.
The most common protocols defined by ITU as a 4G are HSPA+ and LTE. Microsoft Lumia 640 XL LTE Dual SIM 4G and 4G in most devices today rely on one or both of them, which makes 4G the fastest most utilized mobile network.
Why is 4G on the Microsoft Lumia 640 XL LTE Dual SIM important?
4G was created to provide a more reliable internet connection on mobiles, and that’s exactly what it did. 4G technology offers 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 is between 15 to 90 Mbit/s, it can achieve as high as 900 Mbit/s.
Another vital criterion of 4G, is its low latency. We can simplify latency and say it’s the time needed to send data or the delay between the action and the actual response. Reduced latency means a better user experience. 4G Latency is better than 3G by double. The average 4G latency is 50 ms.
With the aid of the VoLTE standard, 4G now presents better voice quality in phone calls and gives users the ability to navigate the internet while making calls.
All of these advantages combined with the low cost of 4G increased the use of Microsoft Lumia 640 XL LTE Dual SIM 4G technology, to include better video conferencing, online gaming, and other real-time interactions.
Get to know 4G bands in the Microsoft Lumia 640 XL LTE Dual SIM
4G and other mobile technologies use radio waves to communicate data. These waves have different lengths and frequencies. To avoid interference between signals, governments and the ITU regulated which regions use which frequencies for 4G.
Each region has been designated certain frequency intervals termed bands. Band number 7 and band number 28 (as an example) are used in the whole world.
What you should be aware of as a consumer is that each cellular operator permits specific bands according to the area, and different phones support different bands. So you have to make sure that your Microsoft Lumia 640 XL LTE Dual SIM supports the bands provided by your local mobile provider.
Here are the Microsoft Lumia 640 XL LTE Dual SIM4G-supported bands:
1, 2, 3, 4, 5, 7, 8, 12, 17, 20, 28, 38, 40;.
