@ALL
I think i'm the 1st one from a teleco company to read this thread.
So here goes, and BTW it's a flop idea.
1 - Someone mentioned that subscriber location is monitored after every 15 secs.well to be exact it's between 2-4 mins.
2 - Robin is right about the blocking of SIM.1st thing CC does it to block the stolen SIM.
3 - As for the RBS connectivity,It's coverage diameter varies from location to location depending on lot of factors.(20-60Kms approax)
4 - RBS can only give u approaximate location of ur car,NOT EXACT.so if u r connected to blue area RBS ur actual location might be somewhere else.so ur car could be around anywhere between 10-30 km radius.
