(How mobile number gets leaked)
How Mobile Numbers Leak: In the world of technology, people now increasingly use smart devices. Smartphones have become essential, making it impossible to move without them. In this context, in the digital age, phone numbers are no longer just a means of making calls. Mobile numbers are also used for social media accounts, banking, online shopping, apps, and a variety of digital services.
Due to this, cases of mobile number leaks have increased significantly. If you also notice these signs, you should understand that your mobile number has been leaked. Let's learn how to prevent this.
The mobile network company has the information.
In fact, when you use a telecom company's service, the company has access to your name, mobile number, and various other account-related information. The company uses this data for service and marketing purposes, as per its rules.
Sometimes, information is shared between different departments within companies. Therefore, it's crucial to carefully review the privacy policy and data-sharing options when purchasing a mobile connection.
Online forms and registration can also be a reason.
It's worth noting that providing your mobile number is now mandatory for online shopping, website registration, surveys, and various services. Registering your number everywhere increases your digital presence.
If a website's data is leaked or the company's data-handling policies are not robust enough, your number could be exposed to unknown people. This could lead to spam calls and fake messages.
Many apps ask for permission.
In fact, you've likely seen the Contacts permission when installing an app. Many apps, such as social media, calling, and messaging, ask for access to contacts. If you grant this permission, the app can access the numbers in your contact list. This means that your number can easily be accessed by an app's system through someone else's contact list. Therefore, before granting contacts permission to an app, every app should check whether it actually needs it.
Telecom company data may be hacked
It's worth noting that even the largest mobile companies aren't completely safe from cyberattacks. If a company's system is breached or a cyberattack occurs, hackers can access users' personal information.
In such a data breach, there's a risk of leaking important information, such as your mobile number, name, address, or account details. Furthermore, by the time you're notified, your important data may have already been taken by hackers.
How to keep your mobile number safe?
For your information, if you want to keep your mobile number completely secure, first go to your mobile operator's account and check your privacy and data sharing settings. Where possible, disable unnecessary data sharing and marketing options.
Additionally, periodically check the permissions of apps installed on your phone. Immediately remove permissions for apps that don't require contact access. Using a separate or virtual number for online registration is considered a safer option if necessary.
