Nowadays almost everyone has a phone. It is necessary for people to have a SIM card to talk on the phone.
Anyone above 18 years of age can buy a SIM card. But for this it is also necessary to submit a valid document. Without this, a SIM card cannot be bought.
Many people buy many SIM cards for good plans and cheap tariffs. Which they do not use later.
If you have also bought a SIM card in this way or someone is using an old SIM card in your name. Then it is better to close it.
For this, you will have to call the customer care center of the telecom company whose SIM you have. And there you will have to tell the reason for closing the SIM card.
After this, some information will be asked from you to check your authenticity. If the information is proved to be correct, your request to close the SIM card will be processed.
For this, you may also have to pay some charge. However, if the SIM is stolen then it is necessary to report to the police station. Only after this you can get the SIM blocked.
