Advantages
1. Completely free
Telegram was officially launched in 2013 by the Durov brothers (Nikolai Durov and Paul Durov, founders of VKontakte, Russia’s largest social network service) (founded by Russian tycoons, who are not short of money).
2. Multi-platform
Supports mainstream macOS/iOS, Android, Windows, GNU/Linux and web version, as well as 1% Windows Phone, and other To 1% Firefox OS, SailfishOS, Ubuntu Touch, BlackBerry, Series 40 & Symbian. Just because your mobile phone and computer can automatically synchronize messages and files, WeChat is a big deal.
3. End-to-end encryption
is so secure that even KB elements agree. Of course, due to the frequent use by Islamic State-related organizations, Telegram officials removed nearly 250 broadcast channels in 2015, blocked their accounts, and continued to remove nearly a hundred channels every day (now KB elements should not be able to use it). Telegram's server system is decentralized and distributed around the world, automatically allocating servers based on geographical location to speed up global response.
4. The group function is powerful
The group supports 200,000 people to join for free, and no payment is required for expansion, which is 200 times that of WeChat. TX is really stingy, what is the upper limit of QQ group? The WeChat group is a joke, the files in the group will expire.
5. It is convenient to publish content
The broadcast channel of Telegram can be regarded as a WeChat public account, which can only publish messages and cannot communicate with each other on the broadcast. Because Telegram is safe and convenient, Akinayama car gods often drive at speed...
6. Robot
Telegram opened the robot API, and in 2017 The payment function was supported in May of this year. Bots are programmed accounts on Telegram that can respond to human instructions and messages. There are many types, almost universal, including robots for searching pictures, robots for searching groups, robots for voting, and robots that can identify animations and their appearance time based on pictures. (Only static images are supported, and the recognition is not 100% successful) The robot can also join the group and become a 24-hour online customer service && administrator. (Or repeater)
7. Convenient and easy-to-use emoticon package
The emoticon package of Telegram is completely shared. When the other party sends the picture, it belongs to the same emoticon. If it is in the package library, you can add it freely after clicking it (it supports taking other people’s emoticon packages as your own with one click).
Disadvantages
1. Registration and login require verification of mobile phone number, and email registration is not possible. (Hey, where’s the promised security?)
Strangers cannot see your mobile phone number, but adding friends to each other will reveal your mobile phone number. Accounts registered with the 86 number in mainland China cannot contact strangers by default (thanks to the miners for prompting the official to ban mainland mobile phone numbers). You can find the official robot to unblock the ban. Search: Spam Info Bot
For safety reasons, mobile phone numbers can be used. Google Voice number, other virtual numbers are also available. (But a long-term available number is required, and a verification code will be received when logging in to the account again on other devices)
2. Cannot be downloaded directly
Official website https://telegram .org/ cannot be opened under normal conditions in mainland China. (Don’t ask, the question is that the server is not working. Like a certain 404 website starting with G, they are all small companies, and the server often convulses)
3. You need to manually change the Chinese interface
After the download and installation is complete, open the software. The default interface is English. It looks difficult. People who have not graduated from elementary school will definitely not be able to understand it. It has successfully prevented many babies from using it.
4. It’s not that safe
You have registered with your own mainland mobile phone number, so what’s the point of talking about security?
The official term "security" means that users' information is relatively safe during end-to-end encrypted communication and is not subject to monitoring by social software companies. It does not mean that it can be used as a place outside the law to do whatever they want.
