How to block SMS from a number?

As title says... seems discourse is down so unable to read old instructions.

My recollection was to text 9999 with the message "BLOCK ........." [without the quotes]

To block unwanted incoming text messages, send a message to the number '9999' with the message 'block' followed by the short code or phone number of the sender you wish to block. For example, to block incoming text messages from 416-999-2430, the message would read: "block 4169992430".
