Does it matter that you didn't receive the SMS after successful registration?

You don't need to worry at this time, because you signed up successfully but didn't send you a text message. Maybe your webpage is blocked and your information has not been submitted. You need to submit the information to the background, and then send a confirmation report to you in the form of SMS after data review and authentication in the background. If they haven't finished the review, they won't send you a message so soon.
