Thanks guys for appreciation.
Spoke to the company who is selling tracker. That comes with pre-paid vodafone sim card. According to them any sim should work.
However according to far east sellers, that system can only take 2-2.5G sim cards which means sim from 3 network will not work with this system.
My kit of sensors and siren is in. When I get sometime, I will play it in my home first and later install it in my car over the weekend (if I get time).
Guys keep the good work going. I hope BBC watchdog also cover BMW cars, so BMW can sort out this issue.
