TikTok outside US

I am a musician from the U.S and have used tiktok to garner an audience of listeners on spotify. It’s going pretty good and I have a decent following now but I wanted to know how I can reach a different country on tiktok. I want my posts to get shown to a primarily mexican audience to reach a new market. I’ve heard about using a proxy and a sim card but I’ve actually never heard anything saying it worked. So does anyone know how to do this? and if so, has it worked for you?
