I have got a very little idea what we can do about it but yes mobile company manufacturers has a role to play in it and they needs to take proper action in this regard to limit the very personal data offered by the tracking technology....
We must distribute our contact no only to those who are well known and and whose genuineness can be established.Recharge should be done regularly from the same shop and a separate mobile no can be kept for talking to family members and very close relatives
