Does anybody know of a GSM module specialized for SMS only? I am thinking there are many applications that do not need voice or data and a module that supports only SMS should:
- Use less power
- Cost much less
- In general much more efficient
With SMS you can do lots of things and I have the impression that is much more efficient than data. I envision a system that is powered by simple AA batteries and that can last for several months.
If anyone knows please post here. I'd be very interested.
