While not specifically a gsm shield question...  Which services (where to get) are best for arduino project that just send some data periodically?
I found some old (2+ year old) posts with links that were all dead, but seemed to indicate AT&T offered $25 sim card that included $15 air time & charged very little for data rates.
suggestions?
