Hello

I received an unsolicited message from a phone number. I deleted it.

A second copy arrived and I deleted that too.

The message says send STOP as a reply and it will be stopped but the web says this is a way to give the sender access to your account and they will charge you £3 every time.

Did i do right to delete it?

How can I block a number?  The system on my iPhone iiOS 8 and Mac Yosemite will not allow it.

How can I change my status (as I do on Skype) to stop these messages safely?

Anythoughts?
