AT&T has ended a promotion that paid $450 for T-Mobile customers to switch to their network. The program launched on January 3rd, which was a response to T-Mobile’s campaign to reward people to switch. The promotion ended January 31st and pointed out that it was a limited-time offer. AT&T still has other promotions such as a $100 discount for customers that want to add an additional line and there is lower pricing for some family plan customers. T-Mobile continues to offer discounts for contract customers that switch over from another network.
