Just 25 days ago i had published a post about SIM swapping crime which is increasing day by day. In that post i had tried to produce how hackers are using SIM swapping technique to empty bank account or for other purposes. I am not a victim of this but i have met many persons who are victims and they come in my service center to understand how they can steal my money from bank, Therefore i started reading about it and always try to find out the way to prevent people from this type of fraud incidents. So now i am here with a way which can help to prevent from hackers SIM swapping technique.
How we can keep our SIM safe?
We usually lock our phone by pattern or face-ID or touch-ID so that can protect from mishandling or misuses but never think that there is a very important small particle inside every mobile doesn't matter it is Smartphone or feature phone. The small particle is known as SIM (Subscriber Identification Module) which is directly connected with users of this particle. Since SIM is directly connected with SIM means lots of feature are stored in SIM. Pattern locking and face-ID can be destroyed easily from third party software but if SIM pin is enable then it is tough to unlock it. Please have a look at this post fully.
You can think that we receive OTP during online banking transaction in our phone then bank recognized you from your SIM number only so if any one will have your details and SIM then he can use that OTP for their own interest.I mean we should give much priority to SIM than our Smartphone or feature phone hence always keep the Smartphone in SIM Locked mode.
What is SIM lock and How to set it?
SIM lock is a security number provided by the SIM provider company such as Vodafone or other like that.. they set an unique number for each SIM chip. Each SIM providers has their own default SIM PIN number such as the default key of Airtel SIM provider is 1234.
How to set it?
Process is very simple it can be done from setting menu then tap on security and privacy and choose SIM lock then by default you will have a question enter PIN number and here you will have to enter your subscriber default PIN frist(IF don't know the default PIN then ask to SIM provider) then enter your new PIN and then Confirm it again Then work done.
What is the benefit of SIM lock?
If we make a habit to keep phone in SIM lock mode then it can be proved as headach for hackers. Suppose hackers has made a clone of your SIM or have got your SIM any how then he will surely insert that in his own phone but he can not unlock it because he will not have your SIM unlock key, so we can prevent fraud incident fairly.
Special warning or suggestion
Don't forget your PIN if you forget then probably the SIM provider company can only help you till then you can't use your phone. However it can prevent us from SIM swapping farly too.
Thanks
