"T-Mobile suggests adding its port validation feature to all accounts. To do this, call 611 from your T-Mobile phone or dial 1-800-937-8997 from any phone. The T-Mobile customer care representative will ask you to create a 6-to-15-digit passcode that will be added to your account."
And then I forget/lose my 15 digit passcode, then what? Either there is a retrieval method that makes the whole thing irrelevant, or else I've replaced one catastrophe with another to no purpose.
Anyone have experience with this, or heard reports of attacks by means of forged physical ID?
