One of the most important in this modern day living right now is to ensure that your old mobile number is no longer linked to your bank account, investment account, or other personal services, otherwise your livelihood may be at the mercy of the new owner.
When you stop using your mobile number over a long period of time, your service provider could reissue the number to someone else, leaving you open to potential security risks.
What does this mean? If your old phone number is linked to your bank account, an investment fund, or two-factor authentication of an important service, once that line is re-allocated to another person, all your notifications and tokens for those services will go to this new owner.
If they are malicious or criminal in nature, then you risk having your money stolen or service shut down or hacked.
That is why it is important to make sure that your old mobile number is no longer linked to your bank account and to any other service.
Remove Your old Phone Number From These Services
So, if you stop using an old mobile number, quickly do an audit to find out if it was attached to any services you use. If it is, you need to login to that service and change the linked number. If it is a bank account, you need to get in touch with your bank to find out how to unlink the number.
