Dear Abhishek,
The details related to entrance are mailed to you and even texted you via text message. You will get email, but if you don't want to risk it then you can restart your number by contacting your sim's dealer. That will be the best option you can go for. Moreover, if we talk about phone number's OTP, that comes on phone number only.
Hope this sorted your query.
Good Luck :)
