Verification message is not getting sent

I recently got a Google subscription, and when I tried to sign up for Antigravity, I got a message asking to verify. It redirected me to a Google verification where I had to scan a QR code, which then redirected me to a message app on my phone. There, I tried to send that message, but it’s failing every time. I don’t know why a simple verification process is made this complicated. I’ve added all screenshots for reference. Please help me with this and let me know if I’m missing a step or doing anything wrong.

Hello @anupam_Dwivedi.

The “Not Sent” error usually occurs because your mobile carrier or device settings are blocking outbound text messages to premium short codes. Please try the following steps:

  • Top up your core mobile balance to cover potential charges for premium SMS routing.
  • Ensure you are using your stock messaging app and that “Premium SMS Access” is set to “Always Allow” in your settings.
  • Disable Wi-Fi on your phone and complete the step using cellular data.
  • Look for an option to “Try another way” on your computer to manually enter your phone number.
  • Or use a VPN to force the system to switch to a different regional verification number.
  • If these attempts fail, wait 24 to 48 hours to reset the security lockout before trying again.
