Video: 10 reasons why Samsung Galaxy S9 Plus is the best smartphone for the enterprise

Samsung will ship and begin selling direct to customers through its online store on May 18.
Outside of the new storage allotments, everything else about the S9 and S9 Plus remains the same. That includes the option to add even more storage using a microSD card.
Pricing for the new Galaxy S9 and S9 Plus is $769 and $889 for the 128GB model, respectively. For the 256GB model, the Galaxy S9 is priced at $819 and the S9 Plus is priced at $939.
Update 9:48 am EST, May, 7: Samsung has let ZDNet know after the preorder ends, the price of the 256GB model will increase to $839 and $959 for the S9 and S9 Plus, respectively. If you want to save yourself $20, order before May 17.
