The two new Galaxy handsets will also be available through Sprint's no-contract, prepaid divisions, Boost Mobile and Virgin Mobile USA, starting April 21.
T-Mobile customers will be able to buy a Galaxy S8 handset for $30 down and $30 a month for 24 months ($750 total) under an equipment installment plan, or a Galaxy S8+ phone for $130 down and $30 a month for 24 months ($850 total), according to the carrier. T-Mobile customers can then add T-Mobile ONE unlimited cellular service or other calling plans at additional cost.
Verizon customers can get a Galaxy S8 handset for $30 per month for 24 months ($720 total) or a Galaxy S8+ for $35 per month for 24 months ($840 total), or they can sign up for Verizon Unlimited service and trade in a working, eligible smartphone and receive a Galaxy S8 phone for up to 50 percent off or $15 per month for 24 months ($360 total). Verizon Unlimited calling plans start at $80 monthly for a single line or $45 per line for four lines.
The new Galaxy S8 and S8+ phones include the same high-resolution, 12-megapixel rear camera and 8-megapixel autofocus front camera used in the previous Galaxy S7 and S7 Edge phones, and both run the Android 7.0 Nougat operating system. The new phones also include the fast charging and wireless charging capabilities from the earlier models.
The S8+ includes a 3,500mAh rechargeable battery, while the S8 uses a 3,000mAh battery. Both models include 4GB of LPDDR4 memory and 64GB of built-in storage, which can be expanded to 256GB of storage through a microSD card. Both models also include Bluetooth V5.0 connectivity as well as WiFi capabilities and are covered with Corning Gorilla Glass 5 on both the front and back of the devices.
The handsets are also IP68 water and dust resistant and include Samsung Knox security capabilities for enterprise users.
The new smartphones will also be offered for sale starting April 21 through Cricket Wireless, Straight Talk Wireless and U.S. Cellular, as well as on BestBuy.com and in Best Buy, Target and Walmart stores.
One of the most promising features of the latest devices is their integration with Samsung's new virtual assistant, called Bixby, which is being developed to give users a wide range of capabilities through voice, touch and text commands.
Bixby is designed to help reinvent Samsung devices so they learn and adapt to the behaviors of their users, rather than requiring users to adapt to the devices.
Bixby will allow Samsung device users to get information, reminders, recommendations and other assistance as the system continues to be developed and added into Bixby-enabled applications.
Both new Galaxy S8 smartphones are also capable of communicating directly with other Samsung products, including home appliances, televisions and other internet of things devices, using Samsung Connect.
Enterprise users can connect with Samsung's DeX desktop experience docking station, keyboard and mouse to bring the computing power of the S8+ and S8 phones to secure desktop computers that will allow them to do their work with Android applications. This will enable smartphone users to effectively extend their workplaces as needed.
The S8 and S8+ handsets are the first new top-of-the-line smartphones from Samsung since the release and eventual global recall last fall of the company's Galaxy Note7 phablet. The Note7 was plagued by hundreds of reports of battery fires and explosions around the world shortly after its release.
Samsung is depending on the success of the new S8 models to regain confidence with consumers and prepare for what will likely be a release later this year of the Galaxy Note 8 to replace the troubled Note7.
