2. WhatsApp


WhatsApp is without a doubt one of the most popular internet phone tools.

To get started, you just need to confirm your mobile phone number. WhatsApp then syncs your contacts, so you can see which of your friends are using the app. Once synced, you can call your WhatsApp friends straight from the app, wherever they’re located, using your internet connection instead of your phone plan’s limited voice minutes.

With WhatsApp, you also get the ability to send instant messages, chat in groups, and share your location, videos, photos, and other media. You can also make video calls. There are desktop and mobile versions, but both you and your call recipient need the app to make calls.

Keep in mind that WhatsApp messages backed up on Google Drive aren’t encrypted, and WhatsApp has exhibited major vulnerabilities to malicious spyware. And while you can’t call landlines, with 2 billion monthly active users, WhatsApp’s online calling potential is unrivaled.

3. Viber


Viber is an increasingly popular platform for making online calls. The free mobile calling app offers desktop and mobile versions and supports seamless calls and communication between the two.

Once synced with your mobile phone number, Viber combs your contacts to find other Viber users. Developed by a former member of Israeli intelligence, Viber offers end-to-end encryption on all calls, texts, and group chats, as well as photos and files sent on the app.

For a fee, Viber Out lets you subscribe to Viber for a local number in various countries that you can use to call non-Viber users and receive calls and texts.

4. Telegram


Telegram is another internet phone app that’s growing in recognition. Telegram allows you to call other Telegram users for free, as well as send text messages one-on-one and in groups.

Telegram is available in desktop, mobile, and web versions. You can share unlimited photos, videos, and files. Telegram features are available anywhere you log in, and you can even make internet calls through the web. Cloud-based infrastructure lets you sync messages between multiple devices.

Telegram has risen in popularity for a few reasons. For starters, its client-side code is free and open-source. Telegram also offers encryption, but keep in mind that it doesn’t encrypt chats by default. Secret chats and voice calls are encrypted end-to-end, but the former has to be manually turned on. That could lead users to a false sense of security.

If Telegram isn’t for you, the other apps on this list should suit you fine. Or try one of these capable Telegram alternatives.

Telegram pricing: Free; Depending on where you live, Telegram Premium, which includes Telegram Business, varies in price.

Pros and cons

Once you sign up you’ll get a Vonage box, which you’ll connect to your router and phone. You’ll then get voicemail, 911, call waiting and forwarding, and even access to weather and traffic information. For a fee, you can add another line or a fax, for instance.

The mobile app syncs your existing contact list, and Vonage users will appear in a dedicated section of the app.

Vonage pricing: Free trial with $10 in credits for new users; Basic at $13.99 per month; Premium at $20.99 per month; Advanced at $27.99 per month (all prices apply to an annual subscription).

6. Messenger


Facebook began life as a social network to connect students on university campuses in the U.S. Not only has it become the most popular social media platform, but you can also use its Messenger app to make free online calls.

To make a call on Facebook Messenger, both users need the Messenger app. Messenger automatically syncs with your Facebook friends, so it’s easier if you and the other party are friends there. Or you can search for users through the search feature.

Messenger doesn’t support phone calls to landlines, but you can make free internet phone and video calls desktop to desktop, desktop to app (and vice versa), and app to app. Messenger works from any web browser.

Just consider the risks of free instant messengers for team communication. Try a workplace messenger instead. Many workplace messengers, like Brosix, provide the ability to make calls.

What is Wi-Fi calling?

Wi-Fi calling is a feature that allows users to make phone calls over a Wi-Fi network instead of using a cellular network. It is especially useful when you are in an area with poor cellular coverage but have access to a strong Wi-Fi network. Wi-Fi calling is also a great option for international calls, as it eliminates the need for expensive roaming charges.

What are VoIP calls?

Voice over Internet Protocol (VoIP) calls are phone calls made over the internet instead of using traditional phone lines. Various devices, such as computers, smartphones, and dedicated VoIP phones, can make internet calls, which often cost less than traditional phone calls. They also offer additional features, such as video calling and screen sharing, that are not available on traditional phone lines.

Can I make international calls for free using online calling apps?

Yes. Some apps offer free calling to other app users who have the same app installed, regardless of their location. Other apps allow you to make calls to both landlines and mobile phones in other countries at a fraction of the cost of traditional phone services.
