Number compatibility

What works:
  • Mobile numbers that support SMS reception
  • In France: mobile numbers starting with 06 or 07
  • Available on Business plan only
What doesn’t work:
  • Landline numbers (09, 01, etc.)
  • Numbers without SMS capability
Don’t have a compatible number?
Contact support to add one to your account. Buy additional numbers

​
SMS doesn’t always work

Why you must use voice call:
  • Not all Allo numbers can receive OTP SMS
  • WhatsApp verification SMS might not arrive
  • Voice call is the most reliable method
Always choose: “Call me” instead of “Text me”

​
WhatsApp calls are not recorded

Important limitation:
  • WhatsApp calls don’t go through Allo
  • No recording
  • No AI summary
  • No transcript
  • Won’t appear in Allo call history
Only regular phone calls through Allo app are recorded.

​
Troubleshooting

Check:
  • You selected “Voice call” not SMS
  • Your number supports voice calls
  • Allo app is open and connected
Try:
  • Wait 2-3 minutes
  • Close and reopen WhatsApp
  • Request new code
Verify:
  • Country code is correct
  • Number format matches your region
  • No extra spaces or characters
Example for French numbers:
If Allo number is 06 12 34 56 78
Enter in WhatsApp: +33 6 12 34 56 78
Wait a few moments:
  • Voice option appears after 1-2 minutes
  • Don’t keep requesting SMS
  • Let timer count down
If still not showing:
  • Close WhatsApp completely
  • Restart the app
  • Start verification again
