Issue in building Twilio

when i open my Twilio account to authentication my phone number. when i click on phone number it is redirecting the page and it showing empty dash board.

Are you able to add your mobile number? If yes, make sure that you add your country code correctly. And sometimes it happens that confirmed authentication messages take a day to reach.

No, i did not able to add my mobile number because page is showing empty dashboard.

Try the same process with different browser.

In this case you can write to the Customer Care of Twilio. As the service is unstable sometimes the developer can help you out.
