Telegram groups let you use the service for free. They sync well
across devices too. You can add up to 200,000 people in a group.
You can share texts, photos, videos, and files easily. Plus, calls
and video chats are end-to-end encrypted. This means they're safe to
use for private conversations.
They're great for community building. You can have group voice chats
with thousands at once. This makes talking with lots of people at
the same time simple and effective.
