Ask HN: Do you know of any SMS-API services that is programmable?

I don't have a data plan, I'm grandfathered into this ~$20.00 plan that just has SMS/Calling. So I was thinking of buying a cheap Android phone and a cheap SMS line that would have internet access (leave it at home) and it would then be able to receive commands by SMS and return say the titles of my most recent emails and I could go in deeper by sending a command like: READ - email number I am aware of GSM modules where you don't need a phone itself. I'm also aware of my lack of Android dev so this is not an easy task. Also regarding the service, who would just give their email credentials to some service. Then it boils down to the cost of the phone (not bad like $20.00) and the additional monthly bill for this new phone, which together with my current bill might be the minimum for a standard data plan. So why bother in the first place aside from it would be cool/awesome to be able to do. Who would use this anyway as most people just have data plans. I also mentioned grandfathered I think a $35.00 plan is cheapest.
