To ensure that nobody can know your phone number on Telegram, you can take the following steps to enhance your privacy:
Adjust Privacy Settings: Telegram provides various privacy settings that you can customize to control who can see your phone number. Go to Telegram settings and navigate to Privacy & Security. Here are some settings to consider:
Phone Number: Set this to "Nobody" or "My Contacts" if you only want your contacts to see your phone number. Choosing "Nobody" will prevent anyone from seeing it.
Last Seen & Online: You can set who can see your last seen status and online status. Choosing "Nobody" will ensure others can't see this information.
Profile Photo: Decide who can see your profile picture. Again, you can choose "Nobody" or "My Contacts" for more privacy.
Username Instead of Phone Number: Telegram allows you to set a username, which can be used by others to find and message you. By setting a username, you can avoid sharing your phone number for initial contact. To set a username, go to Settings > Edit > Username.
Avoid Sharing in Groups or Channels: Be cautious when joining public groups or channels where your phone number may become visible to others. Consider using private chats instead of groups if you want to maintain more privacy.
Use Secret Chats: Secret Chats in Telegram offer end-to-end encryption and self-destructing messages. If you have sensitive conversations, use Secret Chats to add an extra layer of privacy.
Be Cautious with Sharing: Be mindful of sharing your phone number with people you don't trust or who might misuse your contact information.
Manage Contact Sync: If you allow Telegram to synchronize your contacts, be aware that it may make your phone number visible to people who have your contact saved in their device.
Block Unwanted Contacts: If someone with your phone number bothers you, you can block them on Telegram. This action prevents them from contacting you and seeing your information.
It's essential to regularly review and update your privacy settings as Telegram may introduce new features or settings over time. By being proactive about your privacy, you can better control who has access to your phone number and personal information on Telegram.
