Every day, all kinds of stock information are sent to me, and it is annoying to keep pushing it to me.

My solution is to register a mobile phone number.

Find a mobile phone number with no or little monthly rent.

Anyway, receiving text messages and making phone calls are free.

This number does nothing but register.

Just call and don't answer.

This problem will be solved.

Leave this number as long as it is possible to promote sales.

Call, I can't get in anyway.
