Your number may not have been assigned to you due to an error that occurred while your number was being activated. In this case, you can proceed by selecting a new number from the pop-up page or homepage.
Besides, if you have not bought your Premium subscription during second number activation or if you want to use your second number, you can have your second number assigned to you by clicking “Activate” button at the second number section on home page. Since your Premium subscription is active, the number will be directly assigned and activated after number selection.
