Hi we could make use of GSM based traction, which will help us to track the location by means of SMS whenever required.
Hi Praveen, thanks for the reply. But is there any other way we can track the vehicles without GSM. Not sure but can we build an API using GPS devices or are there any GPS devices that already provide API for android and iOS?
If we dont use any Internet or Cellular coverage… the choice left is Two way GPS modems… and may be some GPS modems providers have API’s too…
