If you're part of many Telegram chats—maybe you joined too many of the best Telegram channels—they can quickly become annoying. When this happens, you can always mute a chat without leaving it. This way, you can check it on your own terms instead of getting a ping for every new message. As Telegram keeps growing at rocket speed, many users have expressed their will to support our team. Today we're launching Premium Telegram Premium – a subscription that lets you support Telegram's continued development and gives you access to exclusive additional features.

The encryption is based on 2048-bit RSA encryption, 256-bit symmetric AES encryption, and Diffie–Hellman secure key exchange.

Most of the time, it's better to use a VPN on your phone, but a proxy can still help you get around regional restrictions.
