Send SMS text messages from any number - good sites?

[Dr Lobster*]

for practice joke purposes, i'd like to send somebody (well, a few people) a text message from a number which isn't my own.

anybody know of any good sites which are either free or reasonably priced ? and work?

The only ones I know append a little advert on the end of the message which gives a lot of the game away. Of course if you know any fellow Metropoller with a spare SIM which has x00 free texts a month, you'd be laughing.

Try http://www.e-txt.com/ for their free trial - brilliant piece of software, but you don't need to download it, you can use the Web Interface.

Must be good advice there. It's from the master of pretending to be someone he isn't.
