Many players trying to register on the Taiwan server encounter three main issues:
I saw a player asking about this on Reddit:
"Can't register device? Anyone know why I keep getting this error? I've set up authentication and OTP, but when I try to register my device and request a verification code, I get this error."

The Taiwan server now requires a valid Taiwanese phone number; foreign numbers are usually not accepted.

Taiwan server security protection requires phone verification and device registration. The issue is usually caused by temporary system checks, not the phone number itself, and retrying the process a few times typically allows successful registration.
Before you can fully enjoy AION 2 on the Taiwan server, you must register your device for security protection. Follow the steps below carefully to ensure your account is properly secured and can connect to the game without restrictions.

3. Enter the verification code you received and complete phone number verification.

4. Set a device name, then click Register to complete device registration.

5. After clicking Confirm, a message and date saying “Device Registration Completed” will appear.
