If you are a sprint customer you can go to
[email protected] and report that number and forward everything this number has texted even pictures.
You can also go to your sprint account online (if you don't have one you can create one) and block the number so you won't receive anything else from them. I will have to do that because we have children who play the games on our phones and I don't want them to run across one of those texts that come in. Good luck all.
