Verizon Wireless has rolled out a much-welcomed software update for two flagship phones: the Samsung Galaxy S6 and Galaxy S6 edge.

According to the largest national carrier in the United States, the update targets some pretty particular points, improvements to Wi-Fi and HD voice calling.

Keep in mind that both are Voice Over IP (VoIP) systems. This means that every time a user makes a call over Wi-Fi or taps into HD voice call, they are consuming internet data instead of relying on 2G or 3G connectivity.

The immediate effect of the update includes dropped Wi-Fi calls becoming less frequent.

What is more, Verizon revamped its systems so that clients are able to sign in for Voice over Wi-Fi calling when roaming. This can be activated even when their smartphone is not connected to the Verizon Wireless network.

As the HD Voice Call technology goes, a slew of enhancements are in store.

First off, Samsung upped the earpiece volume of calls, meaning that the technology will be increasingly easy to use. Second, the update will let Verizon Galaxy S6 or S6 edge owners to tap into HD Voice Calls only when they are linked to the 4G LTE network. This means that when you are connected to an older and slower route, HD Voice Calls will be unavailable.

Last but not least, the handset will notify customers who make video calls over cellular data that they are using their own data. This should help clients be more aware of their data allowance and consequently cut the overage costs.

Despite the new features not being revolutionary, they will prove useful to the North American customers. Those who want to make or receive calls using a Wi-Fi network and those who want to make video calls without topping their data allowance will find the new feature a godsend.

The recent update takes the software version on the phones to MMB29K.G920VVRU4CPH1, with no other significant new features landing on the devices.

Verizon recommends that its customers get the software update by connecting to a Wi-Fi network or over mobile data once they secure a strong Verizon Wireless signal. Additionally, the carrier instructs its clients to make sure that the battery of Galaxy S6 and S6 edge is fully charged, as the update could prove lengthy.

The update should land over the air to most devices, but it can be downloaded manually by going into Settings, About Device, Download Updates Manually.

The previous Verizon update targeted at Galaxy S6 and S6 edge devices came out in late May and fixed a series of issues. If you like, you can read all about it in our coverage.

To give you a general idea, that past update fixed a problem where the handsets encountered download errors within the Google Play Store app. Also, this previous update resolved the accessing of Visual Voice Mail.

Samsung's notorious bloatware was trimmed down in the update back in May, and the Amazon Music app has been discarded. One positive change includes making Google "Search" available in the Settings menu.
