Samsung Galaxy S21 Ultra

Samsung Galaxy S21 Ultra

The Samsung Galaxy S21 Ultra is purposefully crafted so you don’t need to choose between video and photo. With a single tap, you can pull super-clear stills — up to 33MP — straight from high-resolution 8K video. The 108MP camera brings you the highest resolution camera you can get on a smartphone for stunning photos. Unleash your creativity by adding an S Pen (sold separately), allowing you to edit with precision and bring your vision to life. The amazing 6.8” screen comes with Samsung’s highest contrast ratio and an adaptive display that automatically adjusts from 10Hz to 120Hz for a faster, smoother scrolling experience that is easy on the eyes while efficiently using the large 5000mAh battery. The Galaxy S21 Ultra was designed to be epic in every way.

Please note: We're working with our cellular partners to bring 5G service to Republic Wireless. Until then, 5G compatible phones will work on 4G LTE. Watch our emails and blog for more Republic Wireless 5G news!

Note: When activating on Republic Wireless' service, the Samsung Galaxy S21 Ultra activates only on our My Choice Plans.

We support only the North American factory unlocked version of this phone, model number SM-G998U1. Models without the final "1" are not compatible with Republic. Some vendors will list this phone by the Manufacturer's Part Number (MPN): SM-G998UZKAXAA, SM-G998UZSAXAA, SM-G998UZTAXAA, SM-G998UDBAXAA, SM-G998UZNAXAA, SM-G998UZKEXAA, SM-G998UZTEXAA, SM-G998UDBEXAA, SM-G998UZNEXAA, SM-G998UZKFXAA.

If you’re unsure whether the phone you’re buying meets these requirements, we suggest contacting the seller directly to verify the information.

Please note: Samsung phones sold secondhand are often different versions that have had their software modified to mimic the factory-unlocked version. These phones may be misrepresented with the model number or MPN that we do support. However, these phones cannot be activated on our network and we cannot be responsible for misrepresented phones sold by third parties. If the product description you are considering includes a note that it will activate only on a GSM network, or if the seller indicates the phone will not activate on Sprint or Verizon, this is not the phone model that we support. Please make sure you are buying from a reputable seller.
