T-Mobile has started notifying Galaxy S8 and Galaxy S8+ customers that their pre-orders will be shipped early. Both handsets make their official debuts on April 21 in the United States, but some customers will get them at least a day early.

Technically, the Galaxy S8 series isn’t scheduled to launch until April 28. However, in most markets, customers who pre-order will receive them around a week early. In the U.S., the pre-order launch was scheduled for April 21, but a text message from T-Mobile confirms the carrier is already packing and preparing orders for shipment.

It will begin shipping those orders on April 19, and though they may take more than a day to reach customers in certain locations, at least some customers will receive them on April 20 — a day earlier than originally promised. T-Mobile made a similar move with the Galaxy S7 series last year, delivering some pre-orders a full week before the official launch date.

Samsung clearly isn’t too strict about its release dates for flagship devices, unlike rivals like Apple. The South Korean company is likely keen to get the Galaxy S8 and Galaxy S8+ into customers’ hands as soon as possible as it looks to forget last year’s Galaxy Note 7 fiasco and capitalize on early excitement for its latest smartphones.

Customers in the U.K., where many carriers are promising April 20 delivery, will be some of the first to get the Galaxy S8.
