WhatsApp, Telegram and Signal comparison: Which one should you use?

WhatsApp annoyed many users after the user agreement it last posted, which everyone should accept. Users have turned to WhatsApp alternatives such as Telegram and Signal. So, which messaging app should you use? We made a comparison between the three notable apps and described their featured features.
WhatsApp has long been much more than a messaging app and has become one of almost all users ‘ must-have apps. Despite the Facebook scandals, WhatsApp still remains a reliable port, while its latest release, which all users must agree to, annoyed many users and caused users to turn to different alternatives.

Among the WhatsApp alternatives, Telegram and Signal were the most popular. While Telegram has been a preferred messaging app by many users in recent years, many users have recognized the Signal app thanks to a tweet shared by Elon Musk.


WhatsApp has more than 2 billion monthly users worldwide, and its owner is Facebook. Because Facebook’s name has been involved in many scandals, it has shaken users ‘ trust. Although WhatsApp offers much broader and more social features than other apps, it has suffered a rapid loss of trust with the privacy policy it recently published and which everyone should accept, and with its failure to protect metadata.

Telegram has more than 400 million monthly users worldwide, developed by two Russians named Nikolai Durov and Pavel Durov. Contrary to what is known, Telegram offers the E2E end-to-end protection protocol, which is the default on WhatsApp, only at any time. It offers a much wider range of features for group interviews than other applications.

Signal has close to 20 million monthly users worldwide and is owned by a nonprofit called The Signal Foundation. Signal hides both your data and metadata with the E2E end-to-end protection protocol, even has a feature that covers your face in photos. But WhatsApp doesn’t even offer as much fun use as Telegram.


The contact limit for WhatsApp groups, which are almost indispensable for all users, is 256 people. Through these groups, you can perform all multimedia sharing and make voice and video calls, albeit with a limited number of people. You can post messages to multiple people simultaneously via WhatsApp.

Telegram has a limit of 200 thousand, a number that cannot be approached about group negotiations. You can think of Telegram groups as social media platforms in their own right. Telegram groups have long been used for surveys, tests, all kinds of multimedia and regular sharing.

You can also create conversation groups through Signal, but you can’t broadcast messages to more than one person at a time. It is also possible to make voice and video calls in Signal groups. You can text yourself via Signal. So you have your own conversation window in the app, you can use this field as a personal notebook.

WhatsApp offers both individual and group voice and video calls. But in Group interviews, the limit is 8 people. Your voice and video calls are protected by the E2E end-to-end encryption protocol, just like your other data.

Telegram has recently added the video-calling feature to its app, perhaps its biggest shortcoming in a long time. Telegram, which already has a voice call feature, recently announced that it will also launch the group voice and video call feature.

Via Signal, you can make voice and video calls protected by the E2E end-to-end encryption protocol. Group voice and video calling have recently been added to the app. It is believed that the same protection will be provided in Group negotiations.

WhatsApp protects all your messages, multimedia and conversations with the E2E end-to-end encryption protocol developed by Open Whisper Systems, known as the name behind Signal. Because this protocol is open source, it is known to offer reliable protection, but WhatsApp does not protect your metadata.

Metadata indicates who you are texting or interviewing, What time, and how long, but the content is not included in this data. The fact that cloud backups are not encrypted is another notable negative feature of WhatsApp. In short, no one reads your WhatsApp messages, but all your other data is open.

Telegram, contrary to what is thought, does not protect all conversations with an end-to-end encryption protocol. Only if you want this feature to be activated on the secret chat screen. In addition, Telegram uses the self-developed MTProto encryption protocol, not the E2E protocol, even in secret chat.

The MTProto encryption protocol is closed-source, so we can’t be sure that it really works. Conversations other than Secret Chat are first encrypted on your device, on Telegram servers, these passwords are decrypted and re-encrypted and sent to the recipient. So Telegram has access to all your message content.

Although it may seem a little suspicious, Telegram notes that to date it has shared 0 bytes of data with third parties or states, and promises that your Messages will not be shared with anyone unless multiple legal orders come from different parts of the world. So Telegram says the guarantee of your data is my brother.

If you need to gather all this information, WhatsApp reaches almost all of your data, except for conversation content, and uses it to customize ads and make money, at least for the time being. With the features it offers, we can say that it is the most social and fun messaging app.

Telegram offers features so wide that you can create custom social media platforms with group chats. But the fact that it uses a closed-code protection protocol, does not protect every conversation, and reaches the content of the conversation is even more suspicious than the WhatsApp user agreement.

Signal should be the number one choice for all users looking for real security. But Signal is pretty boring, at least for the moment. Just like a satellite phone used at the top of the mountain, it allows you to do exactly what you want safely, but does not offer many additional features. However, it is believed that new features will be added as the number of users increases.
