Call and SMS blocking is a feature of the Norton Mob Security.
I took Aravindan's suggestion and installed "Anti Sms Spam". I successfully blocked messages having "expires" or "download" in them. However it did not block a message that contains those words and a button to download something. I do not do such things so I do not know what would be downloaded. The text supposedly came from someone I know, but they said that they did not send it."Anti Sms Spam" is very good and efficient for Messages blocking. You can block based on keywords or numbers which you can define in settings. Option to add whitelist nos is available only in paid version.
Yeah, they are part of most of mobile security apps including Kaspersky. But who wants to pay $30/year to use them when you have free apps which can do the same task....
