Carrion by the Divest team works pretty well as a FOSS spam blocking solution in my experience. Another factor is I changed my number a few years back and I dont give it out to anyone unless necessary. I bought a "free" Sim from a company called FreedomPop for when I need to give out a number and I dont want to share my real number. I keep the Sim off Unless I need a verification text.
