5GE on your phone stands for 5G Evolution. It is a marketing term used by AT&T to show an upgraded 4G LTE network, not true 5G.
In simple terms, 5GE is still 4G LTE, but with improved speed and performance due to technologies like LTE Advanced. It may feel faster than regular 4G, but it does not provide the full speed and capabilities of real 5G networks.
So, if your phone shows 5GE, it means you are connected to an enhanced 4G network rather than true 5G.
