There are many tools around to block unwanted SMSs. Samsung Galaxy S3's Jelly Bean offers a native call&sms blocker too.
But some senders are not phone numbers, they are alphanumeric strings.
I would like to get rid of this spammer, and my provider says they can't block SMSs on their own.
Currently, I wouldn't like to block "anonymous" SMS because I haven't yet received spam (better say mobbing) from undisclosed/private senders.
I've tried to use Root Call Blocker Pro, but it doesn't seem to support named senders too.
Any suggestions on how to deal with this?
