I know all about spoofing. I know you can spoof a call, but I didn't think you could spoof a text. See with spoof calling you can make any number appear on Caller ID along with changing your voice. I found this SMS Spoofing web site....I guess anything is possible.

About SMS Spoofing and How it's Done

Nowadays SMS spoofing is not as easy as it used to be back when we first opened this site. Bulk text messaging carriers, who typically enabled their customers to set their number A.K.A. Sender ID, now feel the need to police their services and restrict their customers from using this feature. An example would be Clickatell. Clickatell is one of the worlds largest bulk SMS providers and their customers probably send millions of text messages a day through their services. To avoid any legal issues with the mobile carriers, Clickatell now restricts the use of the Sender ID so people cannot spoof SMS with any name or number they choose, even though setting your reply address may be a crucial need and is a very fundamental feature of sending SMS messages. Clickatell probably lets certain users set the Sender ID, for obvious reasons, but its not as easy as it was years ago. There are still bulk text messaging providers out there that will allow you to spoof text messages with any name or number, you just have to search around to find them and even demo their services to see if its an unmentioned feature!
