Why can't I get a short message about tobacco registration?

There are several reasons for not receiving it. It may be because the mobile phone number was not entered correctly. Sometimes it's because of network problems, and it's also because the setting of this software is not perfect that you can't receive it.

I suggest you change your mobile phone number or pick it up the next day. Contact the operator to cancel the blacklist. If it is a signal network delay, you can try to get it later.

It is recommended that you try the operation again after some time.
