GPRS Shield v2.0b SIM Card suggestions


I just picked up the GPRS Shield v2.0b shield and I am looking for suggestions on where to get a sim card that will work with this shield and that is relatively inexpensive. I am currently going to be using this for a test bed for text messaging. Not high volume or anything intense just some school projects on a very low budget.

I would appreciate any suggestions. Thanks in advance for you time and help.



I have used the GPRS shield V2.0, I think t is convenient to send message using AT commands, do you think so?

Best Regards,
