Telegram is a messaging app with a focus on speed and security, it’s super fast, simple and free. You can use Telegram on all your devices at the same time — your messages sync seamlessly across any number of your phones, tablets or computers.
Telegram is for everyone who wants fast and reliable messaging and calls. Business users and small teams may like the large groups, usernames, desktop apps and powerful file sharing options.
Telegram is a cloud-based mobile and desktop messaging app with a focus on security and speed. Unlike WhatsApp, Telegram is cloud-based and heavily encrypted. As a result, you can access your messages from several devices at once, including tablets and computers, and share an unlimited number of photos, videos and files (doc, zip, mp3, etc) of up to 2 GB each.
Telegram is more secure than mass market messengers like WhatsApp and Line. We are based on the MTProto protocol (see description and technical analysis here), built upon time-tested algorithms to make security compatible with high-speed delivery and reliability on weak connections.
Yes, Telegram requires a phone number to complete the sign-up process. It helps us prevent spam and give users a reliable way to find each other.
By default your phone number is only visible to people who you’ve added to your address book and who have added you to theirs. You can further adjust this in Privacy & Security settings.
Telegram groups can have up to 200,000 members. You can mute the group to stop receiving notifications, set a custom notification sound and more. Admins can set a discussion group for any Telegram channel.
Channels are a tool for broadcasting your messages to large audiences. In fact, a channel can have an unlimited number of subscribers. When you post in a channel, the message is signed with the channel’s name and photo and not your personal account.
