Best Apps for Free WiFi Calling [With & Without Phone Number]

A WiFi phone call app is a mobile application that lets you make and receive phone calls over a WiFi internet connection instead of using your cellular network. These apps use VoIP (Voice over Internet Protocol) technology to establish a connection between two parties, because of which, they are especially useful in areas with poor cell reception but strong WiFi signals.

Some apps allow you to call regular phone numbers directly, even if the person you’re calling doesn’t have the app. While many require both the caller and receiver to be using the same app for the call to connect.

WiFi calling apps improve call quality where cellular signals are weak, reduce call costs, especially for international calls, and allow you to make calls anywhere with an internet connection. Additionally, they often support features like video calls, messaging, and international calling at lower rates.

You can make calls even in areas with poor cellular signal as long as you have a stable internet connection. This helps reduce dropped calls and improves overall call quality in tricky locations.

Communicating via Wi-Fi calling​ often costs less than traditional carriers, especially for international calls. Some even offer free calling options.

You can use the online calling apps​ on various devices, not just mobile phones. Some apps don’t even require a phone number to make calls, and many let you call regular numbers directly.

Many WiFi calling apps include strong security measures, like end-to-end encryption, to protect your calls. They also have data protection rules to keep your personal information safe.

WiFi phone call apps are easy to set up and use, with options for both voice and video calls. They usually include user-friendly interfaces that make connecting with others easy.

Here are the top online calling apps​ for Android and iPhone users.

Before selecting a WiFi calling app, consider compatibility with your device, call quality, and whether the app supports calling both app users and regular phone numbers. Also, check for features like voicemail, international calling rates, privacy options, and whether the app is free or requires a subscription.

• Compatibility: Ensure the app fits well with your device, and it supports multi-device use across phones, tablets, or desktops.
• Reliability: Check reviews to know how reliable its connection is, and if the call quality is consistent.
• Extra Features: Confirm if your desired online calling app offers extra features, including voicemail and call blocking.
• Convenience: Decide if you want an app that asks for your phone number or not, and check if you can call non-registered users.
• Price: While many apps offer free calls, check if premium plans add enough value to justify the cost when choosing your app.

WiFi calling lets you make phone calls to any person over a WiFi network through your mobile carrier, unlike WiFi calling apps that require both parties to use the same app most of the time.

Enabling Wi-Fi calling is easy. On most Android phones, go to Settings > Network & Internet > Mobile Network > Wi-Fi Calling, and on iPhones, go to Settings > Cellular > Wi-Fi Calling to turn it on.

However, many people confuse WiFi calling with completely free calls, which are not. Calls made through your carrier’s WiFi calling feature usually count toward your regular minutes or plan and mostly incur charges.

One benefit is that it works with any phone number, so you can reach anyone without needing an app. However, it depends on your carrier and device support, and call quality can vary based on your WiFi connection.

Staying connected is easier than ever with WiFi phone call apps that let you make clear calls without needing a mobile signal. They’re perfect for saving money, especially on international calls. With so many options out there, it’s important to choose an app that fits your needs and works well across multiple devices.

However, one major drawback with many of these apps is that both the caller and the receiver must use the same app. If not, you might face high charges for making calls.
 

You can make a phone call without a cell phone using WhatsApp, Messenger, or Google Voice’s web or desktop application. Or, you can also acquire a virtual phone number from Calilio and easily call anyone you like from your computer, laptop, or tablet.

Messenger, Instagram, and WhatsApp are some of the best apps for making calls over WiFi when traveling outside of your country.
