Should I buy another phone number that is not shared with anyone for Telegram?

That is, a number that may be used to register in websites etc, but that no one actually owns.

I just don't want that if someone has my phone number, they can find my telegram user id or whatever its called, and basically know that im on Telegram, potentially know where im active and so on. Because as far as I know, there is no fking way to disable that people can find your Telegram if they have your phone. …

called don etc find find my may phone phone number privacy register telegram websites
