Hello, I want to know how it will work if enable both the SMS & Email verification.

Currently, I have disabled the email verfication. Now, user can instantly access their account after SMS verfication.

If i enable, email verification will it send sms before sms verification or after sms verification.

Its possible to send the email verification(User can verify it later), once sms verfication done they can login to their account(As it is now) and use their account features like post an ad.?

(Here, the thing is most of the user doesn't go to the email to verify the email to activate their account. So, there's a chance of user will not return to the site.)
