Staying connected across borders has never been easier—or cheaper. In the past, international calling meant expensive phone bills and limited talk time. But today, technology has changed the game. You can now make international calls for free using a range of apps and online services, without worrying about roaming or long-distance charges.
In this guide, we’ll show you how to call your friends, family, or clients abroad for free; what tools to use, and some important tips to ensure high-quality connections wherever you are.
1. Use Wi-Fi Calling Apps
One of the simplest ways to make free international calls is through Wi-Fi calling apps. These apps use the internet (Wi-Fi or mobile data) instead of traditional phone lines. As long as both you and the receiver have the same app installed, you can talk without paying anything extra.
Popular Free Calling Apps:
- WhatsApp: Offers free voice and video calls worldwide. Just ensure both users have an internet connection.
- Skype: Ideal for both personal and professional calls. It also supports group calls and screen sharing.
- Viber: Lets you call other Viber users for free and even send voice notes.
- Facebook Messenger: Easy to use and integrated with social media — great for casual conversations.
- Telegram: Known for its security and stability, Telegram supports crystal-clear voice calls.
💡 Tip: Always connect to a strong Wi-Fi network to avoid poor audio quality or dropped calls.
2. Try Internet-Based Calling Services
Some services allow you to call landlines or mobile numbers abroad without charging you. These platforms often give free minutes or credits for new users, which you can use to make international calls.
Top Free Calling Platforms:
- Google Voice: Offers free calls to the U.S. and Canada, and affordable rates for other countries.
- TextNow: Provides a free U.S. number and allows international calling to select countries.
- PopTox: Lets you make free international calls directly from your browser — no app required.

3. Use Free eSIMs with Data-Based Calling
If you’re traveling, you can avoid roaming charges by getting a free eSIM plan that includes mobile data. Once your eSIM is activated, you can use calling apps (like WhatsApp or FaceTime) to make international calls without paying for voice minutes.
At Slick.net, you can get a free eSIM for international travel and connect instantly in over 200+ countries. With data included, you can make and receive calls through your favorite VoIP apps — all at no extra cost.
4. Use Wi-Fi Calling on Your Smartphone
Most modern smartphones now support Wi-Fi Calling, a feature that lets you make calls using Wi-Fi instead of mobile networks.
This is especially useful when you’re abroad and want to avoid roaming costs.
How to Enable Wi-Fi Calling:
- On iPhone:
Go to Settings → Phone → Wi-Fi Calling → Enable - On Android:
Open Settings → Network & Internet → SIMs → Wi-Fi Calling → On
Once it’s turned on, your phone will automatically use Wi-Fi for calls when available — even for international numbers.
5. Combine Apps and Free Data for the Best Results
The best strategy to make international calls for free is combining both — a free eSIM with data and a reliable calling app.
For instance, activate a Slick.net international eSIM, connect to local Wi-Fi or mobile data, and use WhatsApp, FaceTime, or Skype to call anywhere in the world without paying traditional call rates.
This method not only saves money but also ensures better call quality and convenience while traveling.

6. Avoid Hidden Charges
While many services advertise free calls, some might include hidden limits or ads. Always check:
- Whether both parties need the same app
- If the call is free for both users
- Any data usage charges from your mobile network
By using Wi-Fi or free eSIM data, you can avoid these extra costs entirely.
