How to Use Signal for International Calls for Free

Looking to make secure, crystal-clear international calls without racking up expensive phone bills? Signal is a fantastic app that lets you call friends and family worldwide for free. In this guide, we'll walk you through exactly how to use Signal for international calls, making the process simple and hassle-free.

What Is Signal and Why Use It for International Calls?

Signal is a privacy-focused messaging app available on both Android and iOS, as well as desktop platforms. Unlike traditional calling methods, Signal uses your internet connection—Wi-Fi or mobile data—to place calls. This means you can bypass costly international calling fees entirely, as long as you and the person you’re calling both have the app installed.

Here are a few reasons why Signal is perfect for international calls:

End-to-end encryption: Your calls and messages stay private and secure.
High call quality: Signal offers clear audio, even over slow connections.
Free to use: No subscription fees or hidden charges.
Cross-platform support: Call from your phone or computer.

Step-by-Step: How to Make Free International Calls on Signal

Getting started with Signal for international calls is straightforward. Just follow these simple steps:

Download and install Signal: Go to signal.org or your device’s app store and install the app on your smartphone or desktop.
Register your phone number: Open Signal and verify your phone number. This step connects your Signal account to your number and allows Signal to find your contacts who also use the app.
Add international contacts: Make sure you have the full international phone number of the person you want to call saved in your phone’s contacts, including the country code (e.g., +44 for the UK, +91 for India).
Open Signal and find your contact: Launch Signal and tap the pencil icon or “New message” button. Scroll or search to find your international contact.
Start calling: Tap on the contact to open the chat window, then tap the phone icon in the top-right corner to initiate a voice call. If your contact is online with Signal, your call will connect over the internet for free.

Pro tip: For video calls, just tap the video camera icon instead of the phone icon. Video calling on Signal is also free and encrypted.

Tips for Best Call Quality and Experience

To ensure your international calls on Signal are smooth and clear, consider these practical tips:

Use Wi-Fi whenever possible: Wi-Fi connections typically offer better stability and clarity than mobile networks, especially for video calls.
Check your internet speed: For optimal voice calls, aim for at least 100 kbps upload and download speeds. You can use free online speed tests if unsure.
Keep Signal updated: Regularly update the app to benefit from the latest security patches and features.
Close other apps using data: Running multiple apps that consume bandwidth can reduce call quality, so close unnecessary apps during calls.
Use headphones or earbuds: This can reduce background noise and improve audio clarity on both ends.

Common Questions About Signal International Calls

Is Signal really free for international calls?

Yes! Signal uses your internet connection to route calls, so there are no additional charges from Signal itself. However, standard data charges from your mobile carrier may apply if you are not on Wi-Fi.

Do I need the other person to have Signal installed?

Absolutely. Both parties must have Signal installed and registered to make free Signal calls. If your friend or family member doesn’t have Signal, invite them via the app’s invite feature to get started.

Can I call regular phone numbers internationally using Signal?

No, Signal calls are app-to-app only. You cannot use Signal to call a landline or mobile phone number unless that phone has Signal installed.

Is Signal safe to use for international calls?

Signal is widely regarded as one of the most secure messaging apps available. It uses end-to-end encryption, meaning only you and the call recipient can hear the conversation.
