根據Telegram 官網所講，理論上，如果他人有你電話號碼，可以知道你Telegram真身。
Note that people will always see your number if they know it already and saved it in their address book
如果想進一步保障個人隱私：
第一步，鴨記或其他地方購買年卡(多數 100至130元)或購買儲值卡 100元買到5至7張 (能收到SMS便可)。
第二步，TG容許用戶更改電話號碼，而對話紀錄及群組不受影響。
You can change your number in Telegram and keep everything, including all your contacts, messages, and media from the Telegram cloud, as well as all your Secret Chats on all devices
所以只要
go to Settings, then tap on your phone number (just above the username), then ‘Change Number’.
便可以更改號碼。
