T-Mobile's little known NOPORT setting can protect your phone number from SIM swapping.
By Lorenzo Franceschi-Bicchierai
T-Mobile has a feature that gives its customers more protection from hackers trying to steal their phone number, but you probably don't know it exists because the company doesn't advertise it publicly and won't even talk about it.
It's called "NOPORT" and, in theory, it makes it a bit harder for criminals to hijack phone numbers with an attack known as "SIM swapping," a type of social engineering that Motherboard has covered extensively and which is increasingly being used to steal people's phone numbers.
