SMS not received

If some SMS don't reach your Onoff number, what to do depends on the sender.

Verification codes from a service (bank, social network, app…)

Some services refuse to send their codes (OTP) to VoIP numbers such as Onoff numbers. This block is decided by the service, not by Onoff, and can last from a few days to several months. Onoff can't force them to change it.

Email us at support@onoffbusiness.com with the name of the service: we can report the issue to them, with no guarantee of results.

SMS from a regular mobile number

If an SMS sent from a mobile phone doesn't arrive, email support@onoffbusiness.com with:

• your Onoff number;
• the sender's number;
• the approximate date and time it was sent;
• if possible, a screenshot of the message on the sender's phone.

• App notifications are on (see "Receive call and message notifications").
• Your number is active and not expired.
