Receive SMS from special services

Bank codes, two-factor authentication codes, platform alerts: Onoff numbers are real mobile numbers and receive most of these SMS, just like a SIM-based number. Receiving them is free, anywhere in the world, with no roaming fees.

Receive a code

1. Check that your Onoff number is active.
2. Enter it in international format in the service's form (for example +33 6…).
3. Open the Messages tab in the app, mobile or web. Most codes arrive within 10 to 30 seconds.

If the code doesn't arrive

1. Check that the number was entered in international format.
2. Ask the service for a new code.
3. Try another verification method if the service offers one.
4. If the problem persists, email support@onoffbusiness.com with the service concerned and the time of the request.

Limitations

Some senders block numbers that aren't linked to a SIM card: a few online banks and fintechs, some public services. In that case the block comes from the sender, not from Onoff. For a critical service, test delivery before relying on it.
