The 6 Best Apps for Making Internet Calls 2024

Here are the best apps to call landlines, mobile phones, or social platforms using the internet.

The type of service or app you need to make calls on the internet squarely depends on what you’re calling. Google Voice is your best option for calling a landline or mobile phone. Wi-Fi Calling is a good alternative if your carrier and device support it (and most now do). Messenger is best if you never intend to call traditional landlines or mobile phone numbers from the internet.

We’ll list the best apps and services for making internet calls to traditional phone numbers and other online platforms.

    What you should look for in an internet calling app

    You need a Voice over Internet Protocol (VoIP) service to call landlines and mobile phone numbers from the internet. Keep an eye on pricing, as these services typically charge a rate for each minute used—depending on where you are calling—or they may offer a monthly subscription. Most don’t charge you for calling others when using the same service, like a Skype-to-Skype call.

    Also, pay close attention to the security features. You want a service with two-factor authentication so hackers can’t access your account and accumulate charges you can’t pay. Encryption is essential, too, as you don’t want eavesdroppers listening in on your conversations as they zip across the internet.

    Do you have Viasat satellite internet?

    Viasat Voice is a great VoIP option that complements your Viasat Internet service. It supports most existing home phones—just connect it to a Viasat modem or gateway using a standard telephone cord. Viasat Voice is separate from the Viasat Internet service, so you never use your plan’s monthly data allowance to make calls. You can even make Viasat Voice calls using your smartphone.

    Best apps to call phone numbers

    Use the VoIP services listed below to call landlines and mobile numbers from the internet. They start out free, but you may need a subscription for some features or credits to pay calling charges. Both Skype and Viber layer on instant messaging, video calling, and more.

    Best for landline calls—Google Voice

    For simple internet calling to landlines and mobile numbers, you can’t beat Google Voice. It provides free calling within the United States and a free phone number.

    If you need to make international calls, you can add up to $70 in credit using a bank account or credit card stored in your Google Account. Google’s international calling rates start at $0.01 per minute and depend on your call’s destination.

    You can access Google Voice by signing in to in a web browser or mobile app (Android, iPhone/iPad). The service also includes text messaging, voicemail, and free voicemail archiving.

    If, for some reason, you stop using Google Voice for a spell (maybe a year), Google removes the free phone number from your account. You have 45 days to reclaim the number after that. If you miss the deadline, Google assigns the number to a different account. You must then go into the Google Voice settings and select Get a Number.


    • Free nationwide calling
    • Free phone number


    • No emergency calling
    • No direct customer support

    Best for availability—Skype



    • Starts at $2.54 per month for a subscription
    • Starts at $5.00 for Skype Credit
    • Costs $6.99 per month to receive landline and mobile calls
    • Toll charges vary

    • Other: Xbox, Amazon Alexa

    Skype is the tool if you need a universal solution. While it’s native on Windows-based devices, you can also use it in a web browser, on a Mac, Linux—even the Xbox One gaming consoles and newer.

    Skype-to-Skype calls are free, but unlike Google Voice, you must pay to call national landlines and mobile numbers. Calls require Skype Credit to pay for minutes, or you can use a subscription starting at $2.99 per month.

    You need a Skype number to receive calls from landlines and mobile numbers. Microsoft bills you monthly ($6.50), quarterly ($18.53), or annually ($52.26) for a number in the U.S.

    Got a Microsoft 365 subscription?

    The Microsoft 365 Family and Personal plans include 60 minutes per month of free Skype calls.

    Skype also includes instant messaging, video calling, screen sharing, and more. It’s a native pre-installed app on Windows 10 PCs, but you can download the desktop client that feels less integrated into the operating system. The desktop client is also available for macOS and in three flavors for Linux.


    • Native to Windows
    • Widely available


    • Requires a second subscription to receive landline calls
    • Offers no free nationwide calling

    Best for personalization—Viber



    • $0.01–$2.99/min.
    • $5.99/mo. For unlimited worldwide calls


    • Includes autodestruct timer that deletes messages
    • Provides free calls between users
    • Includes tool for creating stickers and GIFs
    • Sends messages, videos, and files
    • Supports group chat and calls
    • Supports user-built communities


    • Desktop: Windows, Mac, Linux
    • Mobile: Android, iPhone, iPad

    Like Skype, there’s more to Viber than making calls to landlines and cellphones. You can make video calls to other Viber users, start group chats, send instant messages, create stickers and GIFs, and set a self-destruct timer to delete your messages after a specific time. It also provides a community component for building and managing unique places to chat.

    And like Skype, the calling aspect—Viber Out—isn’t completely free. You can purchase credit to pay for minutes used or subscribe to a monthly plan. For instance, you can call any landline and mobile number within the United States for $1.99 per month, making it more expensive than Google Voice.

    Unfortunately, Viber does not have a web client for browsers. You must install a mobile app or desktop software to use this service.


    • Supports stickers and GIFs
    • Deletes messages automatically after a specific time


    • No web client
    • No free nationwide calling

    Best apps for app-based calls

    Use these apps if you never plan to call landlines and mobile numbers from the internet. All three services support app-to-app voice and video calling only, so the caller and receiver must use the same platform. For instance, both individuals need a Facebook account to use Messenger.

    Best social media option—Messenger



    • Free


    • Supports voice and video
    • Provides a web client for browsers
    • Includes AR effects
    • Offers different chat themes to personalize conversations
    • Supports fingerprint scanning and face recognition
    • Sends recorded voice or video messages
    • Supports Facebook Pay


    • Desktop: Windows, Mac, Web
    • Mobile: Android, iPhone, iPad

    Messenger needs no introduction. Just over three billion people actively used Facebook by the fourth quarter of 2023, most of whom are likely already familiar with Messenger’s video and voice calling features. That places this service at the top of our app-to-app list due to its widespread use and familiarity.

    If you have kids younger than 13, you can install Messenger Kids to send them messages or chat through video. Parents can manage their kids’ contact lists, monitor their activity, and add their friends. Kids can block contacts as needed, too.

    If you use Windows and Mac, Facebook provides a Messenger app on the Microsoft Store and the Mac App Store, or you can use the web version in your favorite browser.


    • No cost
    • Voice and video calls


    • Can’t call landlines
    • Can’t call contacts outside Facebook

    Best for iPhone to Android calls—Google Duo

    Google Duo
    Google Duo Logo


    • Free


    • Enables video calls between Android and iPhones
    • Uses end-to-end encryption
    • Shares your phone’s screen
    • Supports up to 32 participants in a group call
    • Sends video calls to Android devices that don’t have Google Duo installed
    • Requires a Google Account to use across multiple platforms and devices


    • Desktop: Web
    • Mobile: Android, iPhone, iPad

    Google Duo is Google’s response to Apple’s FaceTime. The difference here is you can get Google Duo on an iPhone, but you can’t get FaceTime on an Android phone. That gives Google the upper hand in the multidevice battle for your calling needs.

    Google Duo supports both audio and video calls on the internet. It also features a Family Mode that lets you doodle on the screen during video calls. The service is free to use and requires a phone number, but you need a Google Account to use this service on multiple devices and platforms.

    Finally, Google Duo provides end-to-end encryption for all voice and video calls. Encryption prevents hackers from listening and watching your conversation as you communicate across the internet.


    • Make video calls between Android phones and iPhones/iPads
    • Call kids using Family Mode


    • No instant messaging
    • Limited group calling

    Best for security—WhatsApp



    • Free


    • Relies on your existing phone number
    • Provides end-to-end encryption
    • Broadcasts a single message to multiple users
    • Shares messages, photos, and videos with up to 256 users simultaneously
    • Records voice messages
    • Shares documents
    • Deletes messages after seven days


    • Desktop: Windows, Mac, Web
    • Mobile: Android, iPhone

    WhatsApp uses your phone number to eliminate the typical security risks associated with username and password combinations. There are ways to use WhatsApp without a SIM card, but one must be in place to receive a verification code when creating an account. You don’t need a Facebook account to use this service, even though Meta owns WhatsApp.

    WhatsApp’s end-to-end encryption is enabled by default, meaning all calls and messages are protected from hacker eavesdropping while they are in transit. You can manually enable two-step verification for added security that uses a six-digit pin, so even if someone obtains your phone number and password combo, new devices require a PIN code to access the account.

    Other notable features include group chat, document sharing, and a built-in camera—it doesn’t use your phone’s default camera app.


    • No login credentials required
    • End-to-end encryption


    • Requires a phone number
    • Requires QR code scan for web version use

    Alternative: Use your carrier’s Wi-Fi calling

    Wi-Fi calling is typically built into smartphones and uses your existing mobile number. Many carriers like AT&T and Verizon support and encourage the use of Wi-Fi calling whenever you’re near an access point.

    So, how does Wi-Fi calling work?

    When you place a call, the Wi-Fi calling component converts your analog cellular calls into data. That data is then sent over a local Wi-Fi connection instead of your carrier’s cellular network. When you leave the local Wi-Fi network, Wi-Fi calling switches back to your carrier’s cellular network until you connect to Wi-Fi again.

    You can enable Wi-Fi calling by tapping through these settings:

    • iPhone: Settings > Cellular > Wi-Fi Calling
    • Android (stock): Phone app > More (three dots) > Settings > CAlls > Wi-Fi Calling
    • Android (Samsung): Phone app > More (three dots) > Settings > Wi-Fi Calling

    According to Apple, approximately 24 carriers support Wi-Fi calling in the United States. Here are a few examples:

    Our verdict

    Use Google Voice if you want to call a landline or mobile number, especially if you’re calling from a computer. It provides free nationwide calling while the international rates cost up to $9.50 per minute. The best alternative is to use Wi-Fi calling if your carrier offers it, which is built into Android and iOS and doesn’t require a third-party app.

    If you’re not calling a landline or mobile number, chances are you already have Facebook’s Messenger app. WhatsApp is a secure alternative, as you don’t need a Facebook or Google account to use it. Google Duo is a good FaceTime alternative for video calling between Android and iPhone owners.
