Adding a test phone number
A sandbox is a test environment, in which you can send SMS messages only to test phone numbers.
Each test phone number is registered in a channel using a confirmation code from an SMS. By adding a number, you agree to receive messages to it.
To add a test phone number:
-
In the management console, select the folder you want to create a notification channel in.
-
In the list of services, select Cloud Notification Service.
-
Select an SMS notification channel you need.
-
Navigate to the Test numbers tab.
-
Click Add test phone number.
-
In the window that opens, enter a phone number and click Get code. An SMS with a confirmation code will be sent to the specified phone number.
Russian phone numbers in E.164 format are supported, e.g.,

Enter the code from the SMS and click Confirm.
