Signal is a secure messaging app. It offers encrypted messages, voice and video calls. Security experts recommend Signal because it’s end-to-end encrypted. This ensures that only your device and the recipient’s device can read the messages you send. The team behind the software operates as a nonprofit, supported by grants and donations. Signal is open source, meaning its code is publicly accessible.
SMSEagle devices support Signal messaging when sending messages from web-GUI or APIv2. The messaging relies on data, so your device should be connected to the Internet via Ethernet or mobile data.
