It’s finally happening: The Galaxy S21 flagship series goes on sale today Galaxy S21 pre-order customers may have been feeling like time was slowing down on them but it’s only been a couple of weeks since the flagship series was unveiled at Unpacked 2021. Now the waiting is over, as today — January 29 — is the day when Samsung starts shipping the latest flagship phones to customers. Meanwhile, those who haven’t pre-ordered the Galaxy S21 can now purchase the phone outright from Samsung’s online shop as well as partner retailers and carriers. Buyers can no longer take advantage of early adopter benefits, so anyone who might want to use the new Galaxy SmartTag will have to buy one separately.
