Problem: political text messages always from a new number. Every day about 30 political text messages. You cannot unsubscribe because they come from a new phone number every day. Seems like they have a reservoir of at least 1000 phone numbers from which the “communicate” their text messages.
Solution: Call and SMS Blocker. You can add keywords which filters out the unwanted text messages. You can still review the text messages in the log.
Block sms with keywords, you can see blocked sms in log. Call and SMS Blocker (so far the winner when it comes to sms blocking)
Area Code Blocking App for Spam Phone Calls on Android: Call Control App
