Grow your page

Hello guys, I have a theme page with over 100k followers in my country. I started a TikTok page and instagram on other country. TikTok getting some views- some videos getting 100-300 other 3500 views. Instagram videos got 300 views and the other two 80 and 10 views. I did not warmup the account. I just created and start uploading. Any recommendations for both apps to increase my views?

Also, any good app for new phone numbers in order to add on my accounts?
