AT&T wins court order to stop T-Mobile's Easy Switch from taking its data

A federal judge has temporarily blocked part of T-Mobile's Easy Switch tool after AT&T argued it was pulling customer data without permission. The injunction bars T-Mobile from accessing certain AT&T information while the lawsuit moves forward.

AT&T sued, claiming Easy Switch relied on AT&T’s systems in a way that improperly tapped its proprietary data. The court’s order keeps that portion of the tool offline for now, but does not end the case. Both companies will continue to argue over how customer information can be used when people move their phone service from one carrier to another.
