Call Security on T-Mobile

When a user calls T-Mobile, he will be asked to verify certain personal information to establish his identity as a customer or someone a customer has authorized to act on their behalf. If the user has requested the use of a customer care password on the account, the user will be asked to verify that password. To establish such a password, T-Mobile would initially send a one-time, randomly-generated PIN to the customer by SMS and require the user to respond by providing the PIN to the T-Mobile representative. Unless the caller’s identity is verified through such methods, it is T-Mobile’s policy not to release any account specific information over the phone. However, generic help like troubleshooting or information about the product and service offerings can be provided without verification. T-Mobile follows the policy to not disclose call detail information over the telephone in response to customer-initiated telephone contacts, even if the account has been verified.
