Samsung Galaxy S9 first received Dual VoLTE support in Russia

The South Korean company Samsung Electronics announced that users of its Galaxy S9 smartphone were the first in Russia to be able to make voice calls in 4G networks from two SIM cards (Dual VoLTE). The service is available for subscribers of MegaFon and MTS operators.

Dual VoLTE function supports VoLTE voice calls in HD quality for any of the used SIM cards at the same time, provided VoLTE is supported by the carrier. Another advantage of this technology is that if before 4G was available only for one selected SIM card, now 4G connection is available for both. Wi-Fi Calling technology is also no longer tied to a single SIM card operating in 4G mode.

Recall that VoLTE technology is a new stage in the use of voice communication and sending SMS in the LTE network: previously, for a voice call in the 4G network, the smartphone had to temporarily switch to the 2G / 3G network and then return back. VoLTE allows you to transmit voice immediately in the 4G network, while it provides an almost instant connection with the subscriber (less than 2 seconds) and high sound quality – the interlocutor sounds like he is at arm's length. If necessary, the user can simultaneously talk on VoLTE and use the Internet in 4G.
