I don't feel comfortable blocking all texts that aren't from people on my contact list. Some of the people that may send me a message: my doctor's office unknown extension, a utility company, a sweepstakes that I entered, a friend trying to contact me, having to use another phone, etc.
But, what I don't want are the endless political texts. I'd like to block any message that contains the words.. Trump, Kamala, Cruz, donation, Republican, Democrat, etc. If I could block texts containing those, you could send them to lala land, for all I care, as long as they don't make it to me.
