I am using my phone number to log in to different accounts as part of my work in the Bank IT Department. However, it seems that my number has been blocked, as I am currently unable to use it anymore.
Error details:
Error code: 399287

After reading another post, I understand that my phone number may have been blocked due to a poor phone reputation.
As mentioned, I only use this number for work purposes. Could you please unblock my number so I can use it as a second-factor verification method? Also, please let me know if I need to contact another portal or open a ticket to resolve this issue.
Thanks in advance for your help.
Best regards,
