In an article recently posted but not too far dated, we are learning that T-Mobile is definitely making changes to prevent sim-swapping. As the article notates, we are in an era of breaches where T-Mobile had several through the years, and their own reporting indicates what the plans are for phone changes.
I can only see that an actor will try to tell the employees they don’t have said number they want, the operation they have in that case where phones are being switched takes place, and the consumer still doesn’t know what’s going on.
I guess we’ll have to see how this works in practice and if we have any problems.
To read all of the details, please read the article T-Mobile introduces a more secure way for authorizing SIM changes and it comes from the folks at Phone arena.
This seems recent, as the article says the changes at T-Mobile went in to effect on December 14th.
