Fortunately, network coverage has been improving over the years, and with the emergence of Wi-Fi technology, you can now make calls over Wi-Fi.

This post explains everything you need to know about Wi-Fi calling in Samsung. You will learn what it’s all about and how to activate it on your Samsung phone.

What is Wi-Fi Calling in Samsung

What Exactly is Wi-Fi Calling?

Wi-Fi calling is a built-in feature on most of the latest smartphones. It enables you to make/receive voice calls over your Wi-Fi network.

Wi-Fi calling works on most Samsung smartphones, but you can also find the feature in other Android and iOS devices.

This feature is sometimes called Voice over Wi-Fi or VoWiFi as it lets you complete calls over your wireless internet connection instead of your regular cellular network.

Wi-Fi calling addresses mobile network issues, and it comes in handy in places where Wi-Fi is available, but cellular signals are weak or non-existent.

Since Wi-Fi calling uses your wireless internet connection, your calls do not go through a cellular network, but your carrier routes the calls over an available Wi-Fi network.

For this reason, you must be within a Wi-Fi network range to use Wi-Fi calling on your Samsung phone or any other compatible device.

Even though Wi-Fi calling is ideally for voice calls, you can also use the feature to send and receive texts or make video calls over your wireless internet connection.

Ensure your Wi-Fi connection is steady and reliable to avoid unnecessary interruptions, disconnections, or call quality issues.

Although Wi-Fi calling does not cost extra, check with your phone carrier or ISP if they charge additional fees for this service.

Also, note that the Wi-Fi calling feature may not be available on all carriers or Samsung devices.

Wi-Fi Calling Explained

How Does Wi-Fi Calling Work?

Wi-Fi calling is an IP telephony system that works using internet protocols, allowing you to place and receive calls over a wireless internet connection. 

This call feature functions like other Voice over Internet Protocol (VoIP) applications like Skype and WhatsApp but uses your Wi-Fi instead of your cellular data plan to make calls.

When you place a call over Wi-Fi, your carrier transmits your voice data through a Wi-Fi network and across the internet to the recipient. 

Your Wi-Fi call will appear like any other regular call, and the recipient won’t even notice that you are placing a call over your Wi-Fi network. Besides, all calls and messages will appear on your regular call and chat logs.

For Wi-Fi calling to work, your phone must support it. The feature must also be available on your carrier. 

Fortunately, Wi-Fi calling is available on most Samsung devices, and the leading carriers support this feature to avoid losing customers to Wi-Fi calling apps and similar web services.

Note: You must have a stable and reliable Wi-Fi connection before placing or receiving calls via the Wi-Fi Calling feature.

Is Wi-Fi Calling Free?

Wi-Fi calling is not free, but it does not cost anything extra outside your cellular monthly voice plan. The charges depend on your carrier, and the rates for your regular cellular calls also apply to your Wi-Fi calls.

Previously, you could make free Wi-Fi calls using Wi-Fi calling apps. However, the recipient must install a similar app on their phones for you to complete your free calls.

Cellular providers now allow Wi-Fi calling to avoid losing customers to these apps. The carriers do not charge anything extra outside the regular monthly allowance. Besides, some providers offer free Wi-Fi calls within various regions.

A point worth noting is that if your Wi-Fi connection has data caps, you might have issues with the Wi-Fi calling feature. Your Wi-Fi calls could eat up into your data plan, meaning you have to purchase more bandwidth from your ISP.

Is Wi-Fi Calling Safe?

Even though wireless networks are vulnerable to hacking and unauthorized interceptions, Wi-Fi calling is generally safe.

First, you must provide your Emergency Contact information before using Wi-Fi calling on your Samsung phone. Your cellular provider and relevant agencies can use this info to get to you in emergencies if they can’t reach you via your cellular network.

Mobile providers also use highly-advanced security mechanisms to encrypt your voice data over wireless networks. Your carrier will route your Wi-Fi over secure wireless networks, guaranteeing your safety.

Does Wi-Fi Calling Affect Your Samsung Battery Life?

Wi-Fi Calling might save or drain your phone’s battery depending on the available signal strength.

If you are in a place with weak cellular coverage, your battery will drain quickly as your Samsung searches for phone signals. Enabling Wi-Fi calling can help preserve battery life, especially if a strong Wi-Fi connection is within range.

Conversely, turning Wi-Fi calling on can drain your Samsung battery if your Wi-Fi network is weak. Your phone will struggle to establish a connection, consequently draining the battery. Turning Wi-Fi calling off can help save your battery in this case.

Can You Place International Calls with the Wi-Fi Calling Feature?

You can place and receive international calls with the Wi-Fi calling feature on Samsung. However, international charges may apply, depending on your carrier.

Some telco providers allow free international calls to the US and Canada over Wi-Fi, making Wi-Fi calling a suitable option when traveling abroad, especially if you don’t want to use roaming services.

The Differences Between Wi-Fi Calling and Cellular Calling
