Check the exact catalog entry
Similar names can represent different products. Google and GoogleVoice, TikTok and ads.tiktok, or Yandex and yandex.taxi have distinct catalog entries. Compare the code you selected with the intended task.
Check the session and the external response
A new session lasts 20 minutes. Read its recorded expiry rather than assuming every saved session uses the newest duration. If the external service refuses a number, follow its rules; do not bypass its restrictions.
What support needs
Keep the original activation and error evidence. Share its ID and time with support, not the SMS code itself. Viewing a help page never cancels or repeats a number request.
