# Regarding TikTok Network Compatibility
Network operators have optimized compatibility for TikTok, yet normal access to all its features cannot be guaranteed on every device. Devices equipped with updated technologies are recommended. Refund requests submitted due to device compatibility issues may not be approved.
## iOS Devices
If you encounter login failures on TikTok, try the troubleshooting steps below:
1. Update your iOS system to the latest version and reinstall the TikTok app.
2. Log in to the official TikTok website via a browser first, then return to the app and attempt to log in again.
## Android Devices
Currently, TikTok is only accessible through its web version via browsers; the mobile TikTok app is temporarily unavailable. For an improved user experience, the TikTok web version is recommended.

# [Fair Use Policy (FUP) Statement]
To maintain network quality and comply with the Fair Use Policy, global telecom operators may impose data restrictions on users consuming excessive data within a short period, which may result in unstable connections or reduced network speeds. For a stable network experience, avoid prolonged video streaming, large file downloads, software updates, personal hotspot tethering, and other high-data-consuming activities.
