The Samsung Galaxy S21+ supports 5G connectivity, but it depends on the variant you have. In some countries, the device is available in a single-SIM configuration, while in other countries, it is available in a dual-SIM configuration where both SIM slots support 5G.
If you have the dual-SIM variant of the Galaxy S21+, both SIM slots can support 5G, and you can use both simultaneously. However, if you use both SIMs at the same time, the primary SIM (Slot 1) will support 5G, while the secondary SIM (Slot 2) will support only 4G/LTE.
It's worth noting that the availability of dual-SIM variants may vary depending on the region and carrier, so it's best to check with your local Samsung website or carrier for specific details about your device.
