No use of phone verified accounts .. You'll need the number again and again, Twitter keep asking the code.. You can buy google voice numbers. I'm growing 23 twitter accounts, I have 10 sim cards and 13 google voice number.
also twitter is worse now a days, last month twitter suspended my 25 accounts, 3 of them were 100k+ and rest were at around 30k followers.
I found jarvee useless for twitter because the follow speed is too slow for twitter accounts( I tried different settings but it never followed more than 200 users per day on one account). So I'm growing accounts manually using chrome extension. Jarvee works great for instagram.
