I recently got a spam text (iphone5) and thought surely there would be a really easy way to block the originator, like push a button that says "block". Wrong! My carrier is Sprint. I found I have to log into my Sprint.com account, go to Limits and Preferences>Block Text>Block only these numbers which allows me to enter phone numbers or email addresses. This is not as convenient as I'd like. You know blocking spam is like wack a mole. You are always one step behind. Reference link Is there an App that might help? Or using Sprint is there an easier way? Thanks!
