Why Google Voice gets refused

Google Voice numbers are VoIP. Messaging, social and AI apps check for that and frequently refuse them. Google Voice also needs an existing US mobile number to set up, so it doesn’t help if you don’t have one.

The alternatives

  • Another free VoIP app (TextNow and similar): same VoIP problem
  • A prepaid SIM or eSIM: accepted almost everywhere, but a monthly cost
  • A temporary mobile number: accepted more often than VoIP, cents per code, balance back if nothing arrives
  • A paid long-term virtual number from a business phone provider: good for calls, still usually VoIP

Which to pick

For a one-time code, a temporary mobile number. For a number you’ll give to people and keep, a SIM, eSIM or Google Voice itself.
