I actually found a guy that is selling something on the lines that I'm looking for:
"Create your own SMS Spam Center | Guide + Software
This is a complete guide on how to setup your own SMS(LONG) Spam Center, it will teach you step by step what you need to do, images included.
This guide is not about Online services that charge you per SMS sent, but about a solid, hardware based, completely scalable system that you will own, and you will be able to send a huge amount of messages at a very very low cost.
You don't need to be tech savy to do this, with my guide anyone can setup this in less than 30 minutes.
Once you find a configuration that works well in your country, you can scale this method to send millions of SMS per day.
The software is included and it will not charge a single cent per SMS sent.
You can use this to spread: malware, phishing websites, anything you want really.
REQUIREMENTS
* You must have access to a 2G/3G network in your region
* About $10 worth of hardware that can be bought online
* A simple Windows machine
PRICE: $50"
I can't tell if it's a scam as I don't really understand what type of hardware would be required and the fact that he's selling software at that price sounds pretty malwarey to me.
What do you guys think?
