title: Is it possible to send messages via Telegram Bot to a specific phone number (not chat_id/username)?
body: <p>I understand that this question has been asked before, but those topics are dated 4 years ago, so I wonder if anything changed.</p>
  <p>TL;DR:
  I understand the concern that sending messages via phone number would make users vulnerable for spam. But there is something I discovered that makes me reconsider this. If I /start a chat with Telegram Bot, chat_id is generated. Interesting thing is, this chat_id is the same for my conversations in other chats. I might be wrong here, but it seems that spam issue should be handled in a different way. Thus, I wonder if there is a possibility to send messages straight to user's phone number.</p>
  <p>Thank you for your time.</p>
