About Signal

Signal provides messaging and calling through mobile and desktop apps. Start by connecting with a contact, sending a short message and checking how device linking works on the devices you use. The official documentation describes encrypted communications and account setup, including where a phone number is required. It is a useful option for groups willing to move their conversation into the same app. Delivery depends on internet access and device settings, and what you share can still be saved by recipients. Before changing phones, review the transfer or backup procedure for your platform, especially if you need to retain conversations.
