While AT&T, Sprint and T-Mobile subscribers gear up for the Galaxy S4 debut later this week, Verizon Wireless is still nowhere to be found. Customers on the three aforementioned carriers will all be able to buy Samsung’s latest and greatest beginning this week, but the nation’s top wireless carrier has yet to announce any news as far as when its customers might be able to purchase the Galaxy S4. In fact, Verizon hasn’t even shared any launch details for the HTC One either, and it’s already available from other U.S. carriers and in other markets around the world. Despite the troubling trend, Verizon customers can at least sign up on Verizon’s website now to be notified as soon as more info becomes available regarding when the Samsung Galaxy S4 might launch.
