Why u dont use ur personal phone number??
Create Telegram account need phone number, if im not wrong since this Apps released CMIIW.
If you are student or still dont have phone number or ur parent not give cellphone/smartphone please wait till they give u :)
need to FYP at least to get organic followers, but if u bought less than 100k followers no problem but make sure u send views and likes everything u posting ur content, but maybe u will hard to get FYP if having to much fake followers/likes.
hope it will help.
