Hello NVIDIA Support Team,

I am trying to generate a free NIM API key on [build.nvidia.com](http://build.nvidia.com/)  
but I am unable to complete phone verification.

Account email: [namnguyen241207@gmail.com](mailto:namnguyen241207@gmail.com)  
Country: Vietnam (+84)  
Phone: +84 372240436  
Issue: OTP is never received on my Vietnam phone number.

Could you please manually verify my account so I can access  
the NIM APIs?

Thank you.
