Port Validation Passcode or Prevent SIM hijacking

Do you have a Port Validation passcode setup on your mobile/wireless account?  If not something you may want to consider…

Does AT&T support such a feature?

To reduce the risk of this happening to you if you’re a T-Mobile customer, call 611 from your cellphone or 1-800-937-8997 and tell a support staffer that you want to create a “port validation” passcode. This is also called a phone passcode or PIN, depending on your provider (most US providers offer this feature now). Motherboard confirmed that Sprint, T-Mobile, Verizon and U.S. Cellular all give customers this option.
