Rebtel – Best for unforeseen disruptions
WeChat – Best for businesses targeting the Chinese market
Vonage – Best for communication consolidation

1. Google Voice – Best for Workplace Efficiency

Price: $10/user/month

Google Voice has become an incredible valuable tools for businesses in 2026, thanks to the bevy of AI-powered features available across the entire Google Workspace ecosystem. For Google Voice specifically, features like AI voicemail transcription and analysis can help your smaller teams handle more calls, improving efficiency across the board.

In our testing, we found the Google Voice app easy to use and set up, with lead writer Conor Cawley going from downloading the app to making a call in just under three minutes. The call handling experience was particularly intuitive, thanks to the sidebar menu. The numbers on the virtual keypad are nice and wide, for ease of dialing, especially on a touchscreen.Check out our Google Voice review for more information

2. Rebtel – Best for Poor Signal Areas

Rebtel provides the best call reliability and quality on this list, because rather than using VoIP technology, it relies on landline infrastructure to make calls. This means that you won’t be reliant on a network connection to call internationally, so unforeseen disruptions like storms and outages won’t get in the way.

In fact, we tested Rebtel on a 4G connection with only two bars and noticed no issues. The audio remained stable throughout the call, with zero packet loss.

3. Ooma – Best for Medium-Sized Businesses on a Budget

Price: $19.95/user/month

Ooma is a powerful VoIP solution that offers pay-as-you-go and pay-monthly calling plans for businesses and personal users.

Its excellent support center, which includes 24/7 live support options and a useful knowledge base, combined with its top-tier customer feedback scores, makes it one of the most reliable VoIP systems we’ve tested.

Ooma boasts a streamlined interface, simplifying tasks like placing outbound calls and adding new contacts. We particularly enjoyed the “New Contact” form, which included a neat notes section for customizing your contacts.

4. Vonage – Best for Communication Consolidation

Price: $13.99/user/month

Vonage offers a full-on business communication hub rather just an international calling app. The platform boasts video, voice, and messaging functionality for an all-in-one experience.

Vonage has far more features than other VoIP providers like Nextiva or Google Voice, making it great for large call volumes. You’ll get:

call queue
spam shield
company-wide call recording
on-demand call recording
toll-free numbers
virtual mailboxes
visual voicemail
group paging, and more

5. WeChat – Best for Business Targeting the Chinese Market

Free, app-to-app international calling, messaging, and video conferencing
One billion users worldwide, but concentrated in China
WeChat Out service provides international call rates

WeChat represents a popular option for messaging and calling, making it a great call app for international calling as well, although it is only available for users in the US, Italy, Thailand, Laos, Australia, China, Vietnam, Malaysia, Saudi Arabia, and Hong Kong (the platform is now banned in India).

The WeChat Out app allows users to call actual phone numbers and landlines through the platform. The China-based app is probably best suited to those in China or Hong Kong, as its more than one billion users are primarily based there, but it’s still an easy-to-use international call app for anyone.

How Much Do International Phone Call Apps Cost?

Most business-facing providers offer unlimited international pricing plans that can cost anywhere from $10 per month to $40 per month. These plans typically include extra tools for unified business communication.

Without inclusive plans, you’ll incur small per-minute call rates when calling mobile or landline phone numbers in other countries. In Google Voice, for example, rates for different countries range from $0.01 per minute to $2.50 per minute.

Here’s a look at the starting price, unlimited plan price, and call rates for the providers listed above.

		Starting price	Price of Unlimited plan	US & Canada
BEST OVERALL
Google Voice	Rebtel	Vonage	Ooma	WeChat
$10/user/month	$10/month	$13.99/user/month	$19.95/user/month	Free

App-to-App vs App-to-Phone: What’s the Difference?

App-to-app international calling involves calling someone that is using the same app as you to avoid international call rates. Apps like WhatsApp, FaceTime, Viber, Telegram, and many others are available for this kind of audio, video, and text communication.

App-to-phone international call platforms are services that allow users to call landlines and mobile devices from an app. This typically incurs a small per-minute charge, although many services have included countries that are exempt from these charges.

What Are the Benefits of VoIP Phone Systems?

The benefits of VoIP phone systems over traditional landlines include saving money, adding flexibility, providing more features, and improving call analytics.

Saving money – Landline infrastructure is expensive, but VoIP can use existing technology like smartphones to enable communication.
Adding flexibility – VoIP systems work with computers, smartphones, and traditional handsets, so you can stay in touch on the go.
Increasing features – VoIP phone systems offer more features, like the ability to forward, block, or re-route calls. You can even send instant messages.
Improving analytics – VoIP systems track more data, so you can better understand how your team communicates in the long term.

Verdict: What is the best international calling app?

Google Voice is the best international call app. This app offers a whole bunch of features, competitive pricing in plans and rates, and functionality for personal use and business needs.

All the apps on this list have their own perks and any one might be a better fit for your particular needs. For example, WeChat is a no-brainer when making calls from China, and Vonage would be our top pick for established businesses.

Frequently Asked Questions

Yes, international calling apps do use your mobile data, because they connect to other devices via the internet rather than traditional phone line infrastructure. You can avoid this by connecting to Wi-Fi.

VoIP, or Voice over Internet Protocol, describes a type of phone system that connects to other users via the internet, rather than through traditional landline infrasture. VoIP calls are more reliable and provide business-facing features like call queue and monitoring.

Generally, international call apps are secure, but it depends on your provider. If you want to make security a priority, we’d recommend finding an international calling app that offers end-to-end encryption (E2EE), which virtually guarantees that you won’t have any privacy issues with the app.

Most services that employ two-factor authentication methods also block non-native numbers to prevent fraud. This can have a negative impact on those trying to get codes while overseas, which is why we recommend switching to an alternative MFA method that doesn’t rely on phone systems.

It is possible to call banks and government agencies with international call apps, but it can be difficult. Many of these kinds of establishments have automated security protocols that block Voice over Internet Procol (VoIP) calls, and there isn’t really a way around that.
