I've never really thought about the data limit. I love IPRoyal as they offer unlimited data through my ISP.
I run a setup of real iPhones connected to a Mac. Each phone runs the native TikTok app – no emulators, no anti-detect browsers. I built custom automation software that handles bulk uploads, scheduling, and account rotation through the actual iOS UI. That's why it's undetectable for Tiktok. The key difference compared to emulator-based tools is fingerprint consistency - real devices have real sensor data, real GPU information, and real device IDs.
