Imagine unlocking your AT&T Samsung Galaxy S21 Ultra 5G, S21 Plus 5G, and S21 5G (G998U, G996U & G991) permanently and using it on any carrier worldwide. Do you envision the benefits should that become a reality? No roaming charges. Freedom to use any SIM worldwide. And a lot more.
The S21 series brings a series of fancy devices that come with large screens and solid battery life. Everything else, including the camera, internal memory, display resolution, and internal features, are great too. And we expect all three S21 models to become the best-selling handsets for 2021.
But purchasing the Samsung Galaxy S21, S21 Plus, and S21 Ultra 5G from AT&T or another network carrier brings some restrictions – even though the monthly contract price is really nice. You can’t use any other carrier’s SIM on the handset; fortunately, you can safely unlock the device.
And as we stated earlier, there are various benefits of unlocking the Galaxy S21 series. Below we’ll explain how to unlock your AT&T Galaxy S21, S21 Plus and S21 ultra with just the IMEI number so that you can make the most of your investment.
