What happens if a scammer gets your phone number?

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.

They can trick automated systems — like your bank — into thinking theyre you when you call customer service.
