I have a strong password, there is also two factor authentication. You may think that you are safe. No, you have to do more to protect yourself.

You may think that your social network security and bank account numbers are the most important numbers in your life. However, nowadays hackers can ruin a lot of your things through your mobile number even with a little effort.

But, you never think about keeping your mobile number safe like your social network password and bank account number. Because if I give that number, who will call me?

Even if you have used the mobile number of any service provider of Nepal Telecom, Ncell, Smart Telecom, your mobile number can be easily targeted by hackers. And for that, hackers only need to work hard.

Why keep your phone number secure?
One phone number is enough for your failure. This is a big shock to you. Think about how many places you have used your mobile number.

When logging in to a site, logging in to a service, logging in to an app, you have to use your mobile number. Your mobile number is also used for password reset if you have forgotten the password of an account.

Not only that, your mobile number is also used in the two-factor authentication required for secure login. In this case, if someone has stolen your mobile, it will be 'you' to some extent.

With the help of your phone number, the hacker will now hack your account one by one using the password reset option.

With the help of the phone, he will be able to take advantage of the bank's automated system to get a lot of information from there. Even data such as your personal messages, personal emails can be made public.

So think about where your mobile number is used. And now think about why it is necessary to keep your mobile safe.

How can a hacker hack your mobile number?
It's a lot easier than you think. Your mobile number can be obtained from anywhere. In some cases, your data may be leaked in case of data breach.

More than that, hackers can find their target number through the internet. He finds the mobile number and calls the telephone service provider on your behalf. The telecom service provider can change your number to its own depending on the answers to the simple questions asked.

In the case of Nepal, a hacker can easily take your SIM card from a telecommunication service provider even if he changes his name to a citizenship. This allows hackers to easily send messages, make calls and gain access to your various accounts from your phone.

To avoid this, if your telephone service is shut down for any reason, you should be able to change the password of the account linked to the mobile number immediately. Otherwise, if he changes the password, all your data will be in his hands.

Or you can understand from the incident that took place in Nepal a few weeks ago about what could happen if someone removes the SIM card you are using.

In some cases, you may never get the SIM card back. Therefore, it is more important to prevent such an incident from happening.

Or taking precaution is the best solution. So now here we are giving you information on how to secure the SIM card.

What can you do to keep your phone number safe?
Just as you have two-factor authentication to keep your social network secure, you can also have a secondary security code to keep your SIM card secure.

For that you can activate it by calling the service provider's customer service center or online. You can call the service center and ask for a secondary password on my SIM card or account.

In that case, no one can take away or change your SIM card without your presence. This service is provided by each service provider. However, the level of security they provide may be different.

If a service provider does not have this service, you can use this service for your own protection. It is advisable to use the service provider's SIM card.
