Whether you’re backpacking across continents, on a business trip, or living abroad, staying in touch with loved ones shouldn’t cost a fortune. Thanks to modern technology, it’s now easier than ever to make free international calls using just your smartphone and an internet connection. But to avoid hidden charges and ensure smooth communication, it’s essential to choose the right tools and setup. This guide explains everything you need to know from using free calling apps to choosing the best travel data plans.
What are international calls?
International calls are phone conversations made from one country to another. Traditionally, these calls are routed through mobile networks or landlines and can incur significant roaming charges. But thanks to technological advances, it’s now possible to call abroad for free if you know the right tools and conditions.
Today, travelers, expatriates, and digital nomads increasingly rely on internet-based solutions to stay connected without breaking the bank. This guide will show you how to make free international calls and which setup works best while traveling, especially with a digital travel companion like eSIM Mexico.
How can you make free international calls using internet-based calling apps?
The most popular and effective way to make free international calls is through VoIP (Voice over Internet Protocol) apps. These apps allow you to call and video chat over the internet no traditional phone line required.
Here are the best free calling apps available today:
1. WhatsApp
Used globally, WhatsApp enables voice and video calls between users via Wi-Fi or mobile data. It’s cross-platform, easy to use, and widely adopted, making it one of the top choices for free international calls. Want to know how much data a call consumes?

2. Facetime (ios only)
For Apple users, FaceTime is a built-in tool offering high-quality calls to any other Apple device user. The best part? No additional app download is needed. Curious about the costs? Read: is FaceTime free internationally.
3. Facebook messenger
Aside from chatting, Messenger supports both voice and video calls. It’s a great option when both parties already use Facebook.
4. Google Meet and Google Voice
These services work best when connected to your Gmail or Google account. Google Voice even offers affordable calling to landlines and non-app users.
Each of these options relies on internet access, so even though the calls are technically free, you’ll need a stable data connection ideally through Wi-Fi or a mobile data plan.
How can you make free international calls using your phone’s built-in options?
Modern smartphones often come with native features that support internet-based calling:
- Wi-Fi Calling: Many Android and iOS phones allow you to make calls over Wi-Fi without needing a third-party app. This feature routes your calls through the internet when mobile service is unavailable.
- VoLTE (Voice over LTE): This boosts call quality and works with Wi-Fi Calling in many cases, though availability varies by country and carrier.
To take full advantage of these features, you might ask: do I need a SIM card for international travel? Not necessarily with an eSIM, you can activate mobile data without switching physical SIM cards.
Calling via local sim cards and esims
Even though internet-based apps are free to use, they require a stable connection. That’s where local SIM cards or eSIMs come into play.
What is an esim?
An eSIM (embedded SIM) is a digital SIM that allows you to activate a mobile data plan without using a physical SIM card. It’s ideal for travelers who need to stay connected without incurring high roaming fees.
Why choose esim over a physical sim?
- No need to swap SIM cards at the airport.
- Instant activation from your phone settings.
- Supports multiple countries and regions.
- Compatible with most newer iPhones, Samsung, and Google devices.

Using local sim cards
Alternatively, you can buy a local SIM card in your destination country. This option works well if your device is unlocked and you plan to stay for a longer period. However, it requires a physical change of SIMs, which may be inconvenient or incompatible with dual-SIM setups.
Tips for making smooth free international calls
To ensure your free calls go smoothly and sound great, keep the following in mind:
- Use Wi-Fi whenever possible. Free public networks are okay for casual use, but avoid sharing sensitive info unless connected through a VPN.
- Use headphones or earbuds. These improve audio clarity and privacy.
- Limit background activity. Close apps that consume bandwidth, like video streaming or downloads.
- Stick to voice calls in low-bandwidth areas. Video calls require more data and a stronger connection.
- Mind time zones. Avoid calling too early or too late for the person you’re contacting.
Are there limitations to free international calling?
While making international calls for free is easier than ever, there are a few caveats:
- Both parties often need the same app. You can’t call a landline using WhatsApp, for instance.
- Data usage can be high. Especially for video calls. Use Wi-Fi when available or monitor your mobile usage with a data plan.
- App bans in some regions. Certain countries restrict or block VoIP services.
- Call quality depends on internet strength. Weak or unstable connections can lead to dropped calls.
