Signal group admins can add members from other platforms via an easily generated shareable link. To begin, first, open your Signal app on the Android or iOS device and click on the three vertical dots at the top right corner. Select ‘New Group’ and add at least one member to make it functional. Following this, open the group chat and again, select the three vertical lines on the top right corner. Click on Group Link > On > Share the link with other users on any social media platform including WhatsApp. Users must note that the method does not export chats from one platform (say WhatsApp) to Signal. However, it is still a convenient way to inform your friends and family to join the Signal app.
A lot of people have been asking how to move their group chats from other apps to Signal, and Signal group links are a great way to get started. Drop a group link into your former chat app of choice like you’re dropping the mic on the way out. pic.twitter.com/q49DeZufBG
