Samsung Galaxy S21 Ultra Cases

Announced on the 14th January 2021 and released just over two weeks later on the 29th January 2021, the Samsung Galaxy S21 Ultra 5G delivers exceptional performance with unrivalled contour-cut camera technology, with the main camera being equipped with a staggering 108 megapixels.

The truly stunning 6.8 inch Dynamic AMOLED 2X display, glass back and aluminium frame are certainly something to behold and more importantly protect. That’s why we’ve collected a fantastic range of phone cases that are sure to fulfil your every need.

With top brands such as OtterBox and Tech21 in store as well as a great range of protective cases and clear case options, you’ll be sure to find your ideal Samsung S21 Ultra case at Box.

Will Samsung Galaxy S21 Ultra cases fit the Samsung Galaxy S21 Ultra 5G?

All cases for the Samsung Galaxy S21 Ultra will work with the Samsung Galaxy S21 Ultra 5G, this is because they are the same phone, with only a 5G model available in the UK. So if you see a case for the Samsung Galaxy S21 Ultra or Ultra 5G, you can be confident that it will fit with your device.

Will the Samsung Galaxy S21 Ultra 5G remain waterproof with a case attached?

Yes, our phone cases will have no bearing on the IP68 dust / water resistance rating that the S21 Ultra 5G comes with. However there are some cases available that add to this, extending the resistance past the current 1.5 meter depth for up to 30 minutes standard.

What Samsung Galaxy S21 Ultra Cases work with wireless charging?

Most S21 Ultra cases will work with wireless charging without any issues, however there are a few exceptions. Cases with a thickness greater than 8mm will start to struggle, especially when used with a weak wireless charger. For ultimate peace of mind we recommend checking our tried and tested list of Samsung Galaxy S21 Ultra wireless charging compatible cases here.
