In recent years, telephone calls have evolved in such a way that now we can make them even via WiFi or through the mobile network . This is what is known as VoWiFi or VoLTE , two technologies that we can activate on practically any Xiaomi mobile device.

Thanks to these technologies offered in turn by a large number of operators such as Movistar or Vodafone, we can achieve a better sound quality than that offered by the classic GSM networks , also reducing energy consumption.

VoWiFi and VoLTE, what they are and how they work

VoLTE is a technology capable of transmitting voice communications over the Internet , in turn using the mobile network. To do this, whether we have a Redmi Note 8 Pro, a POCO X3 NFC or any other smartphone, our voice will be encoded in digital format, thus allowing it to be sent as packets over the network.

The same goes for VoWiFi or Voice over WiFi calls. This allows us to make calls from our Xiaomi, Redmi or POCO using the WiFi connection . Very interesting, especially in areas where there is no mobile coverage.

In both cases we not only achieve higher sound quality , as well as greater clarity and clarity in voice calls, but also lower energy consumption . There is no doubt that activating VoWiFi or VoLTE calls on your Xiaomi will bring you great advantages.

How to activate VoWiFi or VoLTE calls on your Xiaomi in a simple way

In general, VoWiFi and VoLTE calls are disabled on Xiaomi devices . To activate them, we will only need two essential codes, which will allow us to activate these technologies in the following way on any device of the firm:

1. Go to the Telephone application and dial one of these two codes depending on whether we want to activate VoWiFi or VoLTE:
   • * # * # 869434 # * # * to activate VoWiFi
