An SMS message with the code is sent to the user's phone.

The server generates a unique one-time code, usually 4 or 6 digits.

Frequently asked questions

How do you ensure the confidentiality of transmitted information?

Maintaining the confidentiality of the information we receive for authorization is a mandatory condition of the NDA (Non-Disclosure Agreement). We guarantee that we do not share the data with third parties and do not use it for any other purposes.

How long does it take to launch an advertising campaign?

If no sender name registration is required, launching an SMS campaign takes 1 working day. If registration of the sender name is necessary, it can take more than 3 weeks due to mobile operator moderation.
