Final answer:
To join a Telegram group without a link, you can search for the group using keywords or the group name in the Telegram app, or use a group's username. However, joining a private group without an invitation or link is not possible.
Step-by-step explanation:
To join a Telegram group without a link, you can try searching for the group using keywords or the group name in the Telegram app. Telegram has a search function that allows you to find public groups based on specific keywords. You can also ask someone who is already a member of the group to invite you by sharing the group's invite link with you.
Another way to join a Telegram group without a link is to use a group's username. Some Telegram groups have a unique username associated with them. You can search for the group's username in the Telegram app and request to join the group. However, it's important to note that joining a private Telegram group without being invited or having the link is not possible. Private groups require an invitation from a group member or the group admin.
