Urgent: Phone verification OTP not delivered to Vietnam (+84) Viettel number - Need manual API key activation

,

Hi NVIDIA team and moderators,

I am unable to complete SMS phone verification on build.nvidia.com
to generate an API key. The system shows “We sent a one-time password
to the phone number you provided”, but no SMS is ever delivered to
my phone.

Account details:

Steps already taken:

  • Waited 90+ seconds and clicked “Request New Code” multiple times
    (within the 2 requests/minute limit)
  • Tried Chrome, Edge, and Incognito mode
  • Confirmed phone has signal, SMS inbox is not full, and no carrier-level
    blocking on short codes
  • Verified the same phone successfully receives OTPs from other
    international services (Google, banking, etc.)

Could a moderator or the accounts team please manually verify my
account and activate API key access? I’m a developer building an
e-commerce automation project and would really appreciate the help.

Thank you very much,
