If you are in the UAE, you might have trouble logging into your Trend Micro Account when using your mobile number.
What Happened?
Recent changes to our backend systems have affected the ability to log in using mobile numbers. This may prevent you from accessing your account as usual.
What To Do Next
The issue has been fixed. You should now be able to receive SMS from Trend Micro. To ensure a smooth login experience, make sure you have a cellular signal when receiving your Two-Factor Authentication (2FA) code or one-time confirmation code.
