This is impossible for two reasons...
1) There is no API which would use services that cost you money on your behalf (well, except data connections, but when you turn it off, it stays off). Consequently, there is no way for apps to legally intercept SMSes.
2) Some mobile operators do not allow the usage of such apps, to prevent traffic overflows.
You can, however,. find apps which allow you to send location through SMS manually.
