I'm actually trying this method and at this time it worked for me

:
- Get an old phone (Samsung or iPhone)
- Buy a UK or USA SIM card
- Insert the sim then factory reset your phone
- When it restarts it should be start with your sim region (UK or USA)
- Download APK file of Super Proxy (with blue app icon)
- Buy a Static Residential Proxy (2$ / month)
- Setup your proxy in the app > then make connection only with Proxy/VPN you should find this option in the connections config (With this for example if your proxy app crashed or closed you phone will not accept any other connections util you run again the Proxy App)
- Then create a Gmail account -> setup it -> block any authorized GPS / Bluetooth connection
- Install your TikTok app -> create account -> open with Gmail (Do not use sim number or something else)
- Warm up your account for 2-3 days (Like, Follow, Comment) ONLY WITH ENGLISH !! and with your account NICHE ! and DO NOT SPAM
- Post your first video and see the magic happen !
I tried exactly the same steps and I'm getting between 80-90% views from UK (The rest are from Europe and USA)
Good luck
