Simlar - free and secure calls 앱
귀하의 개인 정보를 보호하고 인터넷을 통해 무료로 휴대 전화를합니다.
Simlar is based on the established end-to-end encryption protocol ZRTP. No one can listen to your conversation, not even us. During your first call, you need to match a short code with the person you are speaking to. This protects against man-in-the-middle attacks and only needs to be done once per contact. The app development is driven by the open source community. You can find the source code at simlar.org.
Simlar is free of charge. All you need is an internet connection. The more stable it is, the better your sound quality. The average “traffic” corresponds to 1 megabyte for a 2-minute call. For more details see simlar.org.
