SMS verification for https not working

[ygocollecting]

I am trying to activate https on my site but when i request the sms verification the sms just simply does not arrive.
How can i proceed? Is there another way for verifying it? The phone number i am trying to send the sms to is italian.

Hello!
Could you please provide (if you want in PM) the phone number and the date and time you sent the message? Omit the last three digits.

Bye!
