5G is the new generation of cellular network technology that is designed to be fast, more capable, and more reliable than the previous mobile networks. While your Samsung Galaxy A73 is 5G capable, there are times, if not most cases, when the connectivity will not be in 5G due to signal coverage or the area you are located momentarily.
So to ensure the status of the signal in your coverage area, you may also call the customer service representative of your Mobile Network Service Provider.
