Cannot confirm my Globe Prepaid number that was previously verified on Google Duo

I am trying to confirm my Globe prepaid number on Google Meet, but this error keeps popping up:

"There is a problem with your provider, and we cannot send you a text message. Contact your provider or try a number from a different provider."

The number I am trying to confirm was previously verified on Google Duo. It is also my main number for my Google account and can receive other Google OTPs without any issues.

Is anyone else experiencing the same issue? I already reached out to Globe Telecom, but as usual, they had no idea what I was talking about and instead told me to seek help from Google.
