In my experience, one major disadvantage of using Telegram is the inability to know the status of your contacts. Unlike some other messaging apps, Telegram does not provide information about whether a contact is online or offline. This can be frustrating at times, especially when you are waiting for a response or trying to initiate a conversation. It would be helpful to have an indicator that shows if a contact is currently active or not.
Another drawback of Telegram is the need to open the app in order to receive messages. Unlike traditional SMS messaging or some other instant messaging apps, Telegram does not provide real-time notifications for incoming messages. This means that if you are not actively using the app, you may miss messages until you open it again. This can be inconvenient and may lead to delays in communication.
Furthermore, Telegram does not offer the option to send voice messages. While text messages are often sufficient for most conversations, there are times when being able to send voice messages can be more efficient or convenient. Voice messages allow for quicker communication and can help convey tone and emotions more effectively. The absence of this feature in Telegram can be a limitation for those who prefer or rely on voice messaging.
To summarize, the main disadvantages of using Telegram are the lack of information about contact status, the need to open the app for message reception, and the absence of voice messaging functionality. These limitations can hinder the real-time and efficient communication experience that many users seek in an instant messaging app.
