View designsThe Samsung Galaxy S21 Ultra has a striking camera island: four lenses that blend into the glass through a 'contour cut', instead of a separate block on the back. That's why every case is made to fit the Samsung Galaxy S21 Ultra exactly, with a cutout that fits perfectly around that camera. That way your phone stays protected without the case rubbing against the lenses. You can just keep charging your phone wirelessly with the case on, that's no problem with this model. A case for the Samsung Galaxy S21 Ultra is more than just protection, by the way: it's a chance to show a bit of yourself on a phone you hold every day. Pick a design that fits your style, or upload a photo that tells something about who you are. That way your Galaxy S21 Ultra truly becomes yours, not just a phone like all the others.
Your Samsung Galaxy S21 Ultra case from CaseCompany is only made after you order it. You choose a design from our collection and personalise it with your own name or text, or upload your own photo for a unique photo case. That way you get a case nobody else has.
For the Samsung Galaxy S21 Ultra you can choose from these types: soft case and case with detachable lanyard. All types are made to fit: the cutouts for camera, buttons and charging port are exactly where they should be. Not sure about your model? Thanks to our Always Fits guarantee you can order worry-free.
You have 30 days to change your mind and a 12-month product warranty on every case. Order today, and your case will be on its way soon.

No, we don't recommend it. Even though the phones look alike, there can be small differences around the camera island, the buttons or the cutouts, and that goes the other way too. So pick the case made for your own model, since every case is made to fit the Samsung Galaxy S21 Ultra exactly.
Yes, no problem. The soft case and the case with detachable lanyard are thin enough to just place your phone on a wireless charger, without having to take the case off.
Yes. The case with detachable lanyard is our soft case with a cord attached, so you can wear your Samsung Galaxy S21 Ultra around your neck or over your shoulder. Hands-free at festivals, on trips or just on the go.
Yes. Upload your photo, make a collage or add your own text. You instantly see what your case will look like before you order. Check out our Samsung Galaxy S21 Ultra cases with photo.
Check your phone's settings (Settings > About) or the box. Make sure your phone isn't the Samsung Galaxy S21, Samsung Galaxy S21 FE or Samsung Galaxy S21 Plus, since each of those needs a different case.
Don't just take our word for it

VerifiedDo you have a question? I am available from Monday to Saturday.
It seems that so many retailers give you the option of iPhone cases but I've been using pixels the last few years. I just wanted something different then a bland phone case so being able to make a custom one was fantastic. Really able to show my personality on my case is nice.
