Sometimes we need to block phone numbers for security purposes.
This could happen if you requested 2-step verification too many times, or due to our internal verification checks for your number.
If we've blocked your number you can do 2 step-verification troubleshooting and then try completing your SMS verification again.
But, if you're still getting blocked, please contact us, and our team will take a look into your case.
We understand that this block can cause an inconvenience to you, but we're committed to keeping your account safe and to help you through this process as much as we can.
