I have been getting eight solicitations per day from the 'usual suspects.' My first effort is to enable filtering by "content." All of the randomly generated, fake phone numbers are treated a "Unknown callers" and can be filtered away from the known callers. But they still get through. Based on Wiki, I am testing: disable cell data disable WiFi This makes my phone into just a phone, not a text receiving terminal. Assuming the jerks are getting any feedback that their fecal matter got delivered . . . <no one at home.> The iPhone still makes calls but attempts to send an SMS text from the MacBook failed. Of course, two-part authentication texts will also fail and have to use e-mail. In an ideal world, I could share my contacts list with my cell phone provider and only those SMS text would get through . . . not very likely. I will be investigating firewall solutions. UPDATE: The cable modem detects and logs the SMS text port access but has no way to block it. So I've ordered a Cisco WiFi router and firewall from eBay. This will let me turn OFF/ON the SMS text connections on a cell-phone, only WiFi network. Ordinarily, this would be ON/OFF from my cell service provider. But I want direct control and the ability to capture some packets for a more sophisticated filter. In effect, my custom, contacts filter with all others being blocked. Bob Wilson
