The S21 Ultra boasts a 6.8 inches display, a 5,000 mAh battery, and a 12-megapixel camera (ultrawide). In contrast, S21 5G Plus and S21 have 4,800 and 4,000 mAh batteries respectively and lower screen res. You can also buy an S pen separately and use it on the Galaxy S21 Ultra model.

Unlock Your T-Mobile S21 NOW

If you’re on a budget, it makes sense to buy the S21 from T-Mobile. After all, the price you’d pay to a carrier is much less than what you’d pay to a retailer. However, buying from T-Mobile means you can only use that carrier’s SIM on your device. Other carriers’ SIM won’t work. If you want to use all networks’ SIM on your phone, consider using our reasonably priced Galaxy 21 unlock service to make your device SIM-free.
