Btw, Instagress gives you 3 days of free demo on each new account you add))) if someone has access to cheap sim cards (you will need this because Instagress always asks you to verify your account), theoretically one could create 10-20 spam accounts twice a week and run them on Instagress without paying anythingJust saying...
Yout don't need sim cards..I use online sms numbers works fine. Also to avoid password triggers I only change account name and not password. If you change everything about the account straight away you will definitely get the password request
