What is sim card lock :-

Sim card lock is a best security feature for your mobile, because when you set up sim card lock on your phone whenever you switch on your phone it asks you for password if you have the code then only you can use your phone easily. Without this code you can not access your phone . So as per my idea it is best for your sim to protect from unauthorized users’ hands.

Note :- ( You can enter ten time code only , if you timed out then your sim will permanently get blocked and ask for puk code of your sim . For this you have to know (“How to get your puk code of your sim“).

How to get puk code of your sim :-

Puk code full form is (personal unlocking key), This is a short code which is used to unlock your sim from permanent ban. This puk code is asked when you enter the wrong password multiple times in (sim card pin) then it asks for a puk code. You have to enter the puk code of your sim.

When puk code is asked for your sim to unlock, you have to carefully enter your puk code. Again if you enter the wrong puk code multiple times then it blocks your sim permanently and you never again use this sim. So today i share you ( “How to get puk code of your sim” ). So to do this you have to call your service provider customer care and provide some necessary details which they ask about.

They ask about ( “what is the mobile number of your sim” ), ( “Address verification” ), ( “serial number of your sim card” ) to verify you after this they provide you a (puk code). You have to enter this code again in your mobile and your sim card will unlock after this.

Important note :- As I say if you enter the wrong password for ten times then it asks for puk code. After this you should contact your service provider customer care and share your details with them then they send you a puk code which you have to enter carefully. Please , enter puk code carefully if it fills wrongly then your sim gets a permanent block. Ok then let’s start “how to get your sim lock”.
