Figuring out which international calling app is truly the "cheapest" isn't as simple as finding the one with the lowest advertised rate. It really comes down to how you use it. The real cost is tied to which countries you're calling, how often you pick up the phone, and how long you talk.
The best deal for you will depend entirely on whether a pay-as-you-go, a monthly subscription, or even a free (ad-supported) model makes the most sense for your calling patterns.
Your Search for the Cheapest International Calling App
The market is flooded with apps all promising to be the most affordable way to call abroad. But "cheap" is a moving target. A super low per-minute rate looks great on paper, but if there's a connection fee for every call, it can quickly become expensive for someone who makes lots of short calls.
On the flip side, an unlimited monthly subscription can be a fantastic value for people who spend hours on the phone with family overseas. For someone who only calls internationally a few times a year, it's just money down the drain.
The key to finding true savings is to look beyond the advertised rate and analyze the complete pricing structure. This includes per-minute costs, subscription fees, connection charges, and any other potential costs that impact your final bill.
Breaking Down the Main Pricing Models
To make your search easier, it helps to group the top apps by how they charge. By 2025, the international calling app market has really evolved, offering a wide range of options for different budgets. Some of the most affordable choices, like Roamless, Rebtel, and Localphone, have managed to push per-minute rates incredibly low, sometimes down to $0.003 to $0.01 per minute. You can explore more about these affordable international calling app options to see how their features stack up.
This variety means you can find an app that’s practically built for your calling habits. Before we dive deep, let's start with a quick overview of some popular apps and the pricing models they use.
Comparing Low-Cost Calling App Models
This table summarizes a few leading international calling apps, showing their primary pricing models and the type of user they're best suited for.
| App Name | Primary Pricing Model | Best For |
|---|---|---|
| Google Voice | Pay-As-You-Go | Users needing a U.S. number and making occasional calls to popular destinations. |
| MyTello | Pay-As-You-Go with Credits | Callers who need to connect without a stable internet connection via access numbers. |
| Rebtel | Subscriptions & Pay-As-You-Go | Frequent callers to specific countries who can benefit from unlimited calling plans. |
This gives you a starting point. Now, we'll get into the nitty-gritty of what makes each of these models work—and for whom.
Getting a Handle on What International Calls Really Cost
If you want to find the cheapest international calling app, you have to look beyond the flashy per-minute rates they put on their homepage. Those numbers are just the beginning. The final price tag is a mix of different charges, and if you don't know what to look for, you can get hit with some nasty surprises on your bill.
An app with a super-low rate might look like a bargain, but it’s often not the most economical choice once other fees are tacked on. On the flip side, a subscription plan can be a lifesaver for one person and a total waste of money for another. Let's dig into the four key factors that determine what you'll actually pay.
Per-Minute Rates: The Obvious Starting Point
This is the number everyone sees first: the price you pay for each minute you're on the phone. But it’s not one-size-fits-all. Rates can swing wildly from one app to another, and they almost always change depending on where you're calling and whether it's a landline or a mobile number.
For instance, calling a landline in the UK might be as cheap as $0.01 per minute. But with that same app, calling a cell phone in a more remote country could easily jump to $0.25 per minute or more. This is your base cost, but it's almost never the full story.
Connection Fees: The Price of Saying "Hello"
Some providers tack on a connection fee, which is a small, one-time charge that hits your account the second the other person picks up. It might only be a few cents, but if you make a lot of short calls, these fees add up fast.
Think about it: if you make ten two-minute calls in a day, an app with a $0.05 connection fee just added an extra $0.50 to your bill before you even factor in the minutes. For someone who makes fewer, longer calls, this fee isn’t a huge deal. The whole model of pay-as-you-go international calls can be tricky, so you need to know if these fees are part of the equation.
Subscription Plans: The All-You-Can-Call Model
Subscriptions flip the script. Instead of paying by the minute, you pay a flat monthly or annual fee for a bundle of minutes or even unlimited calls to certain countries. This is often a fantastic deal for expats or business owners who are constantly calling one or two specific places.
A $10 monthly plan for unlimited calls to Mexico is a no-brainer if you’re on the phone for hours every week. But if you only make a single 30-minute call to Mexico a month, a pay-as-you-go rate of $0.02 per minute (just $0.60 total) is obviously the smarter financial move.
Hidden Charges: What’s Lurking in the Fine Print
Finally, you have to watch out for the sneaky costs that can inflate your bill without you realizing it. These are the most frustrating charges because they come out of nowhere.
- Call Rounding: Does the app round up your call time? A call that lasts just 1 minute and 5 seconds could be billed as a full 2 minutes, effectively doubling the cost of that first minute.
- Credit Expiration: Some services make you use your prepaid credit within a certain window, like 90 or 180 days. If you don't, that money just vanishes.
- Currency Conversion Fees: If the app charges you in a different currency, your bank or credit card company might add its own conversion fees on top.
It's also worth looking at the bigger picture. For example, some people might find that the best cell phone plans for living in Mexico already include international calling packages that are a better value than any standalone app. By pulling all these threads together, you can get a clear view of the true cost and find the app that's genuinely the cheapest for how you make calls.
Comparing the Top Low-Cost Calling Apps
Finding the cheapest way to call internationally isn't just about spotting the lowest per-minute rate. The real cost—and your actual experience—comes down to how these apps work behind the scenes. The "best" choice really depends on where you're calling, how often you call, and whether you've got a solid internet connection.
Let's cut through the marketing noise and compare the top contenders: Google Voice, MyTello, Rebtel, and Localphone. We’ll look at them not just on price, but on the stuff that actually matters—how they connect your calls, their global reach, and how easy they are to use day-to-day.
Google Voice: The Go-To for US Connections
Google Voice has been a heavyweight in this space for years, and for good reason. Its killer feature is the free U.S. phone number you get, which lets you make and receive calls, texts, and voicemails from anywhere. If you're an American living abroad or just need a consistent U.S. line, it's an incredibly useful tool.
For international calls, it’s a simple pay-as-you-go system. The rates are often very low, sometimes just a few cents a minute to popular countries. The catch? It's pure VoIP (Voice over Internet Protocol), meaning your call quality is completely at the mercy of your Wi-Fi or mobile data signal.
- Calling Method: Purely VoIP, so you need a stable internet connection.
- Best For: Folks tied to the U.S. who need a permanent American number and make occasional international calls from places with reliable internet.
- Limitation: Getting started can be a pain. You typically need an existing U.S. phone number to verify your account, which locks out many international users from the get-go.
MyTello: The Smart Choice for Bad Internet
MyTello brilliantly solves one of the biggest headaches of VoIP calling: what to do when your internet is spotty or nonexistent. It uses a clever hybrid system that gives you options. You can call over Wi-Fi like any other app, or you can use its local access number feature.
This offline method is a lifesaver. The app dials a local number in your country, then connects you internationally through its own network. You end up using your regular cell minutes for the local part of the call, but you get a rock-solid, data-free international connection. By 2025, MyTello has become a favorite for its budget-friendly pay-as-you-go model, with rates starting as low as $0.01 to $0.02 per minute.
MyTello’s superpower is its ability to work without the internet. By routing calls through local phone lines, it gives you the reliability of a traditional call at the low cost of an app. It's perfect for travelers or anyone who can't always count on a good Wi-Fi signal.
Rebtel: The Specialist for Frequent Callers
Rebtel is built for people who call one or two countries a lot. While it has standard pay-as-you-go rates, its subscription plans are where you find the real savings. For a flat monthly fee, you can get unlimited calling to specific countries, which can save you a fortune if you're constantly on the phone with family or business partners abroad.
Just like MyTello, Rebtel gives you connection choices. You can use VoIP when your internet is good or switch to their "Local Numbers" feature to route the call over your mobile network for better quality. That flexibility makes it a reliable option for important conversations that can't be choppy.
- Calling Method: Offers both VoIP and Local Number connections, so you can pick what works best.
- Best For: Expats, business owners, or anyone who makes frequent, long calls to the same country and prefers a predictable monthly bill.
- Consideration: Its subscription deals are only a good value if your call habits line up perfectly with the countries included in their packages.
Localphone: The King of Low Per-Minute Rates
If your top priority is squeezing every last penny out of your calling budget, Localphone is your app. It focuses on one thing: offering some of the absolute lowest pay-as-you-go rates you can find. There are no complicated subscriptions, just straightforward, cheap calling.
One of its coolest features is the "Incoming Number" service. You can buy a local phone number in another country, and when people there call that number, it forwards directly to you anywhere in the world for a tiny fee. And yes, it also supports multiple calling methods, including VoIP and local access numbers. If you're exploring different ways to connect, our guide on the best apps for Wi-Fi calling is a great resource.
To help you see how these services stack up at a glance, here’s a breakdown of what makes each one unique.
Detailed Comparison of Leading Calling Apps
This table offers a clear, side-by-side look at the key features and ideal use cases for each app, helping you quickly identify the best fit for your specific calling needs.
| Feature | Google Voice | MyTello | Rebtel | Localphone |
|---|---|---|---|---|
| Primary Model | Pay-As-You-Go | Pay-As-You-Go | Subscriptions & PAYG | Pay-As-You-Go |
| Internet Required? | Yes (VoIP only) | No (Access numbers) | No (Access numbers) | No (Access numbers) |
| Standout Feature | Free U.S. Phone Number | Offline Calling | Unlimited Country Plans | Inbound Local Numbers |
| Best User Case | U.S.-based callers | Travelers with poor Wi-Fi | Frequent, long-duration callers | Cost-conscious global users |
Ultimately, the right app comes down to your personal situation. Consider where you call, how often, and the reliability of your internet before making a choice.
Which Calling App Is Cheapest for Your Situation?
Looking at per-minute rates and subscription fees on a website only tells you part of the story. The real test of the cheapest international calling app is how it stacks up against your actual, real-world calling habits. An app that’s a money-saver for one person could easily be a costly mistake for another.
To really illustrate this, let’s walk through three common scenarios. By looking at the needs of an expat, a global business owner, and an occasional traveler, you'll see exactly how different calling patterns demand different solutions. This approach will help you pinpoint your own usage profile and find an app that actually saves you money.
This decision tree gives you a quick visual guide to see which plan type might be the best fit, depending on how often you call and your internet access.
As you can see, high-volume callers usually get the most value from a subscription. If you only call now and then, pay-as-you-go is almost always better. And for those without steady internet, an app with an offline calling feature is a must.
Scenario 1: The Expat
First, meet Maria. She’s an expat living in the United States and calls her elderly parents' landline in Spain every single evening. These aren't quick chats; they're long conversations, often lasting an hour or more. What she needs is predictable, rock-bottom pricing for calls to one specific country.
- Calling Pattern: Frequent, long calls to a single destination (Spain).
- Monthly Usage: Around 30 calls, averaging 60 minutes each (1,800 minutes total).
For Maria, a pay-as-you-go plan would get expensive fast, no matter how low the per-minute rate seems. The clear winner here is an app like Rebtel, which offers an unlimited calling subscription to Spain for about $8 per month. That flat fee gives her total cost certainty, so she never has to watch the clock. An app without a subscription option would be a terrible fit.
Scenario 2: The Global Business Owner
Now, let's consider David. He runs a small business and works with clients all over Europe and Asia. His days are filled with lots of quick international calls—confirming a meeting, clarifying a detail, or chasing an invoice. His calls are short, rarely over five minutes, but they span a dozen different countries.
- Calling Pattern: High volume of short calls to many different countries.
- Monthly Usage: Roughly 100 calls, averaging 4 minutes each (400 minutes total).
A subscription model just won't work for David; no single plan would cover all the countries he needs to reach. Worse, any app with a connection fee would be a budget-killer, tacking on a charge for every single one of his 100 monthly calls. His best bet is a true pay-as-you-go app with consistently low rates and absolutely no connection fees.
This is where a service like Google Voice really shines. For example, Google Voice continues to be one of the most practical international calling apps worldwide in 2025, especially for freelancers and business owners, thanks to its incredibly low rates—like $0.01 per minute to some countries. It has no setup fees or hidden charges, which is exactly what David's high-frequency, short-duration calling pattern requires.

Scenario 3: The Occasional Traveler
Finally, there’s Sarah. She travels abroad for vacation a couple of times a year. She only needs to make a few crucial calls on her trips, like calling the hotel, booking a tour, or getting in touch with her bank back home. A big challenge for her is that she often finds herself with spotty or unreliable Wi-Fi.
- Calling Pattern: Infrequent, essential calls from various countries, often without good internet.
- Monthly Usage: Very sporadic. Maybe 10-15 calls over a two-week trip, then nothing for months.
For Sarah, both subscriptions and VoIP-only apps are non-starters. A monthly subscription would be a complete waste of money when she’s not traveling. An app that only works over the internet would be useless the moment she needs to make a critical call from somewhere with poor reception.
Her best option is a pay-as-you-go app like MyTello or Localphone that features offline calling through local access numbers. This setup guarantees she can always connect, and because she only pays for what she uses, the cost is minimal. The credit she buys won't expire, so it'll be sitting there waiting for her next adventure.
By matching your own calling habits to one of these profiles, you can figure out which pricing model—and which app—will truly be the cheapest for you.
Choosing Your App and Getting Started
You’ve seen the different pricing models and walked through the real-world cost comparisons. Now it's time to actually pick an app and start calling. The truth is, the "cheapest" app isn't a one-size-fits-all answer; it's the one that lines up perfectly with how you make calls.
Let's cut through the noise. Below are my top recommendations for different types of callers, followed by a simple, no-fuss guide to get you set up. The goal is to get you saving money on your very next international call.
Our Top Recommendations Based on Your Needs
The best app for you depends entirely on your situation. Here’s who I’d recommend these services to, based on years of seeing what works for different people.
For General Use and US-Based Callers: Google Voice is tough to beat as an all-rounder. You get a free U.S. number and incredibly low pay-as-you-go rates to most major destinations. It's a fantastic tool for personal calls or even for small business owners who want a dedicated U.S. line.
For Frequent Callers to Specific Countries: If you talk for hours with family or clients in just one or two countries, Rebtel is your best bet. Their unlimited calling subscriptions deliver predictable, flat-rate costs that will always be cheaper than paying by the minute for high-volume use.
For Travelers and Users with Unreliable Internet: MyTello really shines when you can't count on a solid Wi-Fi or data connection. It uses local access numbers to connect your calls, meaning you can place a call without any internet at all. For travelers or people in areas with spotty service, this feature is a lifesaver.
The key takeaway here is to look at your own phone habits. Where do you call the most? How long are your typical conversations? Is your internet connection solid? Answering those questions is the final step to locking in the genuinely cheapest option for you.
Your Quick Start Guide to Making Your First Call
Once you've made your choice, getting up and running is fast. The exact screens might look a little different from app to app, but the core process is always the same. Here’s what it looks like.
Download and Install the App
Simple enough. Just head to the Apple App Store or Google Play Store, search for your chosen app (like MyTello or Rebtel), and hit "Install." On a decent connection, it’ll be on your phone in under a minute.Create Your Account
Open the app and follow the prompts. You’ll usually need to enter an email, set a password, and verify your phone number. They'll send you a quick SMS code to punch in—this links the app to your real number and keeps your account secure.Add Calling Credit or Choose a Plan
Before you can dial, you need to load up your account. If you went with a pay-as-you-go app, this means buying a credit bundle—think $5, $10, or $20. If you chose a subscription, you'll select the plan for the country you need and pay for the month. All major credit cards and digital wallets are typically accepted.Make Your First International Call
This is the easy part. Go to the app's dial pad, type in the full international number (don't forget the country code!), and press the call button. The experience feels just like a normal phone call, but your wallet will definitely notice the difference.
Frequently Asked Questions About Calling Apps
When you're digging into international calling apps, a few questions always seem to pop up. Even after you've compared rates and features, there can be some details that aren't immediately clear. Let's tackle the most common questions we hear so you can choose your next calling app with confidence.
Think of this as the final check-in before you start making those cheap, clear calls. We'll clear up everything from the types of numbers you can dial to the tech working behind the scenes.
Can I Call Both Landlines and Mobile Phones?
Absolutely. Pretty much every international calling app will let you reach both landlines and mobile phones. The catch, and it's a big one, is the per-minute rate. Calling someone's mobile is almost always more expensive than dialing a landline in the same country.
And that price gap can be surprisingly wide. For instance, a call to a landline in France might be a steal at $0.01 per minute, but calling a French mobile number with the same app could easily jump to $0.08 per minute or higher. It’s a smart habit to always check the specific rates for both number types before you dial—it’ll save you from any billing surprises.
What Is the Difference Between a VoIP Call and a Local Access Number?
Getting your head around this is key because it directly affects your call quality and reliability. The two technologies are fundamentally different.
VoIP (Voice over Internet Protocol): This is the standard method for most apps. Your call travels over the internet using your Wi-Fi or mobile data. The quality of a VoIP call lives and dies by your internet signal. A strong, stable connection gives you a crystal-clear call, but a spotty one leads to choppy audio, delays, and dropped connections.
Local Access Number: Some apps, like MyTello and Rebtel, use a clever hybrid system. When you initiate a call, the app dials a local number right there in your country, using your standard mobile minutes. From there, the app seamlessly routes the call internationally over its own network. This is a brilliant solution if you're traveling or just live somewhere with flaky internet, giving you the reliability of a classic phone call.
The real win with a local access number is its dependability. By taking a shaky internet connection out of the equation, it lets you make stable, high-quality international calls from just about anywhere, even with a weak data signal.
How Do I Check the Exact Rate for a Specific Country?
You should never trust the advertised "starting at" rate. The best international calling apps are transparent and make it incredibly easy to find their exact pricing.
You'll usually find a "Rates" or "Pricing" page on their website or right inside the app. All you have to do is select the country you're calling from and the one you're calling to. The tool will then show you the precise per-minute cost for dialing both landlines and mobiles there. Make this a non-negotiable step before you add credit or place a call.
Are There Any Truly Free International Calling Apps?
Yes, but they come with a huge string attached. Services like WhatsApp, FaceTime, and Facebook Messenger let you make free calls to other people who also use the same app. This is great if the person you're calling is also online and has the app installed. For a deeper dive into these kinds of services, our article on Skype call costs and alternatives has some great insights.
The limitation is that these free services can't connect to a regular phone number. If you need to call a landline or a mobile, you’ll always need a paid service. So, the hunt for the cheapest international calling app isn't about finding free app-to-app calls; it's about finding the absolute lowest price to connect to real phone numbers anywhere in the world.
