How to change network mode on Samsung Galaxy


Billions of dollars have been spent by mobile operators in recent years to improve cellular network coverage. Despite this, in our country there are still places where mobile communication leaves much to be desired. Fortunately, most operators offer a new Wi-Fi calling feature that allows you to make or receive messages from almost any place where a Wi-Fi connection is available.

In this article, we will talk more about Wi-Fi calls and smartphones that support the new technology. You will also learn how to enable and use this feature.

What are Wi-Fi calls?

The first thing you need to know about Wi-Fi calls (Wi-Fi Calling) is that they do not require special equipment or applications. This is a free service offered by many mobile operators around the world.

For many people, their first introduction to Wi-Fi calls came from Skype, WhatsApp, or Google Hangouts. Mobile operators have decided to keep up with third-party applications, so they offer a built-in function in smartphones to make Wi-Fi calls.

Benefits of using Wi-Fi calls through an operator

There are several advantages to using Wi-Fi calls from your mobile operator. Unlike a third-party provider, for example, Skype, WhatsApp and others, you can use the phone bar and the contact list of your phone to make Wi-Fi calls.

In addition, there is a smooth transition between cellular and Wi-Fi calls. When your smartphone loses a cellular signal, the device automatically switches to Wi-Fi.

When to use Wi-Fi calls

Of course, the most obvious option for using Wi-Fi calls is when you are in a dead zone of cellular communications. Also, Wi-Fi calls will be useful in places with poor coverage.

For example, next to my house there is a coffee shop with amazing Wi-Fi. Unfortunately, the building in which it is located has poor cellular coverage. In this case, Wi-Fi calls are a terrific opportunity to connect with another person.

How to enable Wi-Fi calls

To enable Wi-Fi calling on your iOS device, open “Settings »>“ Phone ”>“ Wi-Fi calls". On this screen, switch “Wi-Fi calls on this device"To position"On". It is worth noting that on iOS devices, by default, Wi-Fi calls are disabled.

The activation of Wi-Fi calls on Android depends on the device manufacturer. In most cases, you can find Wi-Fi calls in the wireless and network mode of your smartphone in the “Additionally».

How do I know if I have Wi-Fi enabled?

After you turn on Wi-Fi calls in the settings, your smartphone will determine the best time to use it yourself. When your smartphone uses Wi-Fi calls, you should see a Wi-Fi icon next to your carrier’s name at the top of the screen.


Thanks to the new technology of Wi-Fi calls, dead zones of cellular communication are no longer a problem. As long as you have access to a Wi-Fi network, you can make calls.

The technology is currently under development, so you should ask your operator if it supports Wi-Fi calls. If yes, then be sure to enable this feature in the settings of your smartphone.

What are the networks for mobile communications

There are three generations of the network, the main difference is the speed of the Internet. The higher the generation, the faster the Internet:

2G (GSM, indicated by the letter G or E on the device) - the slowest Internet and lowest power consumption,

3G (WCDMA, on the device is designated as 3G, H or H +) - the average speed of the Internet and the average power consumption,

4G (LTE, referred to as 4G on the device) - the highest Internet speed and average power consumption.

What are the network modes

Network mode is a rule (algorithm) by which a mobile device will connect to a cellular network. By default, the device operates in automatic mode:

If the device supports 4G and there is such a signal - the device will connect to it,

If the device does not support 4G or there is no such signal, the device will connect to 3G,

If the device does not support 3G or there is no such signal, the device will connect to 2G.

The ability to connect to a particular generation of the network depends on the device: if the device supports only 2G, then it will not work to connect to 3G or 4G. You can find out which network generations your device supports in the support service.

In addition to the automatic mode, there are others:

Only 3G - the device will only search for a 3G network. If the 3G signal is weak or not, the device will not catch the network.

Only 2G - the device will only search for a 2G network. If the 2G signal is weak or not, the device will not catch the network.

There is no “Only 4G” mode.

Some operators (Tele2) do not have a 2G network in certain regions (Moscow). Keep this in mind when buying a phone - for example, Galaxy Star Advance only supports 2G and it simply won’t work with Tele2.

When do you change the network mode

If you’re not using the Internet, turn on the “Only 2G” mode - the device will discharge more slowly.

If in the place where you are using the device, there are no 3G or 4G networks or the signal is very weak, turn on the “Only 2G” mode - the device will discharge more slowly and communication will be better.

In all other cases, changing the network mode does not make sense.
