Vivo V11 Phone setup for LTE network Mode

This September of 2018 Vivo is launching their new device (Vivo V11) and we try to test this new device that Vivo launch this year.

The settings and other features of this phone has advantages and setting its the network mode need more understanding. The network mode that you can see is only set to 2G/3G/4G and no LTE even if the sim is LTE ready. This will made you confuse about the phone. After learning that 4G+ is the LTE network mode of this phone then this phone is fine.

In this article you will understand more about the Network System of a Phone.

The network that Vivo shared in their Phone Network shown in the ff:

FDD-LTE AND TDD-LTE

FDD-LTE – it uses a frequency division duplex or paired spectrum.  The uplink and downlink has 10Mhz at a symmetric that uses two frequencies at the same time.

TDD-LTE –  uses a frequency that is unpaired spectrum.  The TD LTE uses time division

What is VoLTE- It is a Voice over LTE

VoLTE is a voice over LTE. Its a voice calls over a 4G LTE network.  Our connection before just use the 2G and 3G connection.

Since 2016 major cities in the Philippines supports LTE for data and SMS but signal drops to 3G/4G whenever a call action is initiated thus affecting the internet speed and voice quality.

Note: Our Internet Service providers doesn’t have yet this option in the Philippines. Smart is working their VoLTE this year (2018) and hope they will implement this project by the end of this year.
