How to activate VoLTE & ViLTE on your Android device?

ViLTE technology or video calling without internet is a technology that allows users to make video calls without internet. Band phone also has this capability as one of the phones with this technology. In this article, while teaching how to set up this service on a band phone, we will also provide explanations about this technology.

The first stage

The user must make sure that the desired operator has VoLTE or ViLTE coverage in the geographical area.

The second stage

In Irancell operator, by default, the video call feature is enabled without the need for internet, but in the first mobile operator, the user must first dial the command code 10*2431* through the mobile phone to activate this feature.

The third stage

Activate the settings on the phone itself. The user must also activate the VoLTE and Carrier Video Calling options through the phone settings section.

After performing the above steps and if all the steps are done correctly, now we should see the word HD on the antenna of the phone (in the upper right part of the phone). In this case, all the settings are correct and you can make a video call with any other person who has a VOCAL and whose operator is the same as yours, without the need for the Internet.

Of course, we must also point out that sometimes, although everything seems to be correct, when trying to make a video call, the user fails to do so. This is only because the network is busy. In this case, the user can increase his chances of making a successful video call by waiting and trying again after a while. The last thing you should pay attention to is that in the phone band settings section and in the Preferred Network Type section, the selected option must be 4G or 5G.

What is ViLTE and how does it work?

Video over LTE technology (video through LTE) or ViLTE for short, is the name of a technology that allows mobile phone users to contact other users without the need for the Internet and based on multimedia subsystems through IP (IP Multimedia Subsystem or IMS for short) Create an image. ViLTE uses exactly the same control protocols that VoLTE (Voice over LTE) technology uses. ViLTE technology uses the H.264 codec to encode and decode video streams. The main advantage of this codec compared to the 3G-324M codec (which was used in video calls on the 3G platform) is its much higher quality. One of the most important points that should be considered in relation to this technology is that it should have a higher priority than other streaming video services in which delay is not of high importance, so that the quality of the video call does not drop. So far, many devices from different brands have been launched in the market with this technology. VOCAL smartphone also supports this technology, and users of this phone can make video calls with other people who have a band, without the need for the Internet.
