By having your cell number, a scammer could trick caller ID systems and get into your financial accounts or call financial institutions that use your phone number to identify you. Once the scammer convinces your carrier to port out your number, you may never get it back. Scam porting is a big problem for phone owners.
What happens if a scammer has your phone number?
If someone steals your phone number, they become you — for all intents and purposes. With your phone number, a hacker can start hijacking your accounts one by one by having a password reset sent to your phone. They can trick automated systems — like your bank — into thinking theyre you when you call customer service.
