Is a USA sim required for TikTok?

I don't live in the USA but I've heard that you NEED a USA sim in order to go viral on TikTok

No, you do not need a US SIM to go viral in TikTok. TikTok is available globally, and you can use it from any simcard or even over just Wi-Fi.
However, you may see the region-specific content on TikTok when you sign in from a specific geo (SIM), so to go viral for a specific geo, you can set your location to that geo or use WiFi instead of SIM.
