There was a
new law passed at the end of 2019 to address robocalls. It toughened the penalty but more importantly required the phone companies to install anti-spoofing software in their system. This should detect when callers are not showing the actual phone number they are using. The roll out of this improvement is ongoing now.
The law also directs the FCC to " to create rules that will help protect subscribers from receiving unwanted texts or robotexts, which are also plaguing smartphone users."
The present head of the FCC is Ajit Pai who spent some of his career at a lawyer for Verizon and is viewed as a friend of the telecom industry and a foe of regulation of that industry. It will be interesting to see what new regulations the FCC suggests.
At least Congress has shown some interest in helping with your spam text problem.
