You should know that answering unknown numbers can be potentially dangerous at times. This is because stalkers can stalk you via your smart phones as well. Social engineering is one of the two very easy ways stalkers can track you. They might get into your social circle and gain your trust to wheedle out your personal information and then they can use that information against you.
Stalkers can also gain access into your smart phone and track you easily without you even knowing one bit about it. For this they can get physical access to your smart phone or store malware or spying software which they can then use to access your contacts, your logs, your conversations and also pinpoint your exact location by viewing your exact location when your phone’s GPS is on.
Well if a stalker is stalking you and letting his activities known to you via phone, you can find him easily. If you have a number, you can use it to track the stalker and hand him over to the authorities. What you can more easily do is hand over the stalker’s number to the authorities and they can easily track his exact location using his phone number. Even if he is calling you using new numbers every time, phone tracking will enable the authorities to know when the user calls using a new number from the same phone. GPS tracking and reverse tracking services have enabled people to now find about the exact location and owner information of anyone using a specific phone number online.
