Telegram is an instant messaging with a focus on speed and security and a good alternative to WhatsApp. Telegram supports group chats with up to 200 contacts, puts a strong emphasis on security and provides generous multimedia support.
High level of privacy and security
One of Telegram's main focus is security and privacy compared to WhatsApp. For example, Telegram features something called "Secret Chats" - an encrypted chat connection that self-destructs messages similar to SnapChat and prevents others intercepting them. There is even a self-destruct option that will delete your whole account if you don't log in for a set length of time.
It was this security that started attracting users to Telegram in the first place, and WhatsApp now owned by Facebook, this looks set to increase. The developers also claim that they do not sell or share user data with third-parties, there is no in-app advertising and yet it's completely free to use.
Send files up to 1.5GB
Telegram also features a good level of multimedia support with up to 100 people and allows sharing of all file types up to 1.5GB although you may find uploading and downloading quite slow. You can send batches of photos rather than just one at a time and you can store pretty much as many images as you want because Telegram allows unlimited online storage.
Like WhatsApp, Telegram also supports leaving brief voice messages although unlike applications such as Skype, you can't actually actually make voice calls.
An excellent secure alternative to WhatsApp
As a free alternative to WhatsApp, that offers more security, Telegram is a very interesting proposition.
Personalized stickers arrive!
Telegram already offered celebrity stickers, but they were rather limited. Now you can create your own stickers by preparing images and following the instructions. You can share your work with other people as well as use stickers created by them.
