Best WiFi Calling Apps

Staying in touch has never been easier, thanks to WiFi calling apps that let you make voice and video calls over the internet, bypassing traditional phone networks and avoiding roaming charges. Whether you want to call friends abroad, manage business calls, or simply save on your phone bill, here’s a detailed look at the top WiFi calling apps for 2025, their standout features, and what makes each unique. Let’s look at the best WiFi calling apps:

In-Depth Look at the Leading Apps

• WhatsApp

WhatsApp stands out as one of the most popular WiFi calling and messaging apps globally, offering free, end-to-end encrypted calls and messages. Its primary appeal is the ability to communicate internationally without incurring roaming fees, as long as you’re connected to WiFi or have mobile data access. This makes WhatsApp especially attractive for travelers and expatriates who want to stay in touch with friends and family at no extra cost.

The app’s intuitive interface ensures ease of use for people of all ages, and its group calling and media-sharing features make it ideal for families and social groups. WhatsApp’s robust privacy protections, including end-to-end encryption, ensure that only you and your recipient can access your conversations, providing peace of mind when using public or unsecured networks abroad.

Pros: Free, secure, widely used
Cons: Both parties need WhatsApp

• Google Voice

Google Voice offers users a free US-based phone number for calls, texts, and voicemail, making it a practical solution for those who want to maintain a US presence while traveling or living abroad. Its voicemail transcription and call forwarding features add to its appeal, especially for freelancers and business users.

However, Google Voice’s international support is limited, and it is best suited for users primarily communicating within the United States.

Pros: Free US calls, integrates with Google
Cons: Limited international support

• FaceTime

FaceTime is Apple’s proprietary calling app, seamlessly integrated into iOS and macOS devices. It delivers high-quality audio and video calls and is known for its reliability and ease of use among Apple users. However, its exclusivity to Apple devices limits its cross-platform compatibility, making it less versatile for those who need to communicate with Android or Windows users.

Pros: High quality, seamless for iOS users
Cons: iOS only

• Viber

Viber is another strong contender, offering free voice and video calls, group chats, and a feature called “Viber Out” for affordable calls to landlines and mobile numbers. Its security features, including end-to-end encryption, and a variety of fun additions like stickers, make it popular in many regions, especially for international travelers and those with family abroad.

Pros: Secure, fun features, global reach
Cons: Regional popularity varies

• Telegram

Telegram, while primarily recognized for its focus on privacy and large group chats, also supports voice and video calling. Its reputation for robust security and the ability to host massive group chats makes it a favorite for users who prioritize privacy, though it is less commonly used for calls compared to messaging.

Pros: Secure, robust privacy, large groups
Cons: Not as widely used for calls

• Facebook Messenger

Facebook Messenger is widely used due to its integration with the Facebook platform, making it easy to connect with friends for voice and video calls. The app offers a range of fun features, including stickers and filters, but ongoing privacy concerns and data usage can be drawbacks for some users.

Pros: Huge user base, fun features
Cons: Privacy concerns, data-intensive

• Talkatone

Talkatone provides users with a free US phone number for WiFi calling and texting, making it a useful tool for travelers or those without a mobile plan. However, it is supported by ads in the free version and is limited to users in the US and Canada.

Pros: No SIM needed, works on WiFi/data.
Cons: Ads in the free version, US/Canada only

• TextNow

TextNow similarly offers a free phone number and unlimited calls and texts over WiFi, supported by ads, with paid options for an ad-free experience. Its ease of use and affordability make it attractive for budget-conscious users, though call quality can vary.

Pros: Budget-friendly, easy setup
Cons: Ads in the free version, variable call quality

• Slickcall

Slickcall focuses on affordable international calling, offering free credits for new users and referrals, as well as 24/7 support and auto top-up options. While some features require payment, its low rates and ability to call landlines make it a practical choice for frequent international callers.

Pros: Cheap rates, free credit, call landlines
Cons: Ads, some features paid

• RingCentral and Vonage

Finally, RingCentral and Vonage are business-oriented solutions, that provide advanced features for teams and offices, such as call management, conferencing, and integration with other business tools. These services are user-friendly and reliable, but their monthly plans and additional fees for advanced features may be more than what casual users need.

Pros: Business-focused, easy to use
Cons: Extra fees for advanced features

Choosing the Right WiFi Calling App

When selecting a WiFi calling app, consider:

• Compatibility: Ensure the app works on your device and is popular among your contacts.
• Cost: Most are free for app-to-app calls; check rates for calling landlines/mobiles.
• Privacy: Look for end-to-end encryption if security is a concern.
• Extra Features: Business users may need voicemail, call forwarding, or conference calling.
• International Use: Apps like Viber, WhatsApp, and Slickcall excel for global communication.

Each of these apps brings unique strengths to the table, and the best choice depends on your specific needs, whether that’s free international calls, business features, privacy, or cross-platform compatibility.
