Phone porting scam: How to protect yourself on different carriers

Written by |

Thieves are increasingly stealing people’s phone numbers in a new scheme known as “porting” or “port-out scamming.”

A phone porting scam involves criminals knowing a few pieces of personal information about you and having your number “ported” to another service provider.

If a scammer knows your phone number, name and other data, they can impersonate you by calling your mobile service provider and take total control of not only your phone — but in some cases your identity.

What you need to know about cell phone porting scams

Cell phone number porting can have numerous consequences: Once a thief has ported your number to another service provider, they can tap into other accounts of yours that require codes or a text sent to your phone. That means your bank accounts, email service and more could be at their fingertips in no time.

Mobile service providers are doing what they can to alert their customers about the scam. Recently a member of Team Clark received a message from T-Mobile about porting scams. It read:

“Fraudsters are attempting to compromise personal bank accounts by gaining access to your wireless account,” the message said. “They do this by guessing common security PINs, such as birthdates, sequential numbers (e.g., 12345678), or repetitive numbers (e.g., 11111111).”

Phone porting scam: How to tell if you’ve been victimized

You may be wondering how to prevent or stop this scam. First, you need to know how to detect it. One tell-tale sign that you’re being victimized is if your phone suddenly switches to “Emergency Call Service Only” or something close to it. If you see that, call your mobile phone service provider immediately.

According to the Better Business Bureau, when you see this message about emergency calls only, “That’s what happens when your phone number has been transferred to another phone.”
