6 best encrypted VoIP apps

Most messaging apps facilitate text-based communication. When it comes to VoIP calls, very few offer encrypted calls. Therefore, encrypted VoIP apps are valuable.

Standard applications with VoIP support collect personal data in the background. Your data may be exposed when you do not use the encrypted VoIP app. No one should neglect data security and privacy.

If you take your privacy seriously, you need encrypted conversations. It is unwise to use a non-encrypted VoIP application. Luckily, there are now multiple applications that meet these needs of users.


Telegram is a free communication application. For some, it is more social media than a communication app. You need a phone number to start using the app.

The "Secret Chats" feature makes Telegram stand out among the encrypted VoIP apps. This feature ensures that all calls are made with end-to-end encryption. Telegram states that it does not log even in itself.

Telegram's downside is that it doesn't extend end-to-end encryption to standard VoIP calls. "Secret Chats" must be used to take advantage of the encrypted calls.

Google Voice

Google Voice is a cloud-based phone system. It allows you to manage communication channels more comprehensively. Their plans are a favorite of many people looking for only a few features because of their low cost.

Signal will be the right VoIP choice if you want security to be at the forefront. You may experience delays in conversations, but they are very seldom. As long as you can tolerate them, it's a hassle-free application.
