Because that's all that the carrier allows.


In many. parts of the world, including the U.S., carriers have shut off their 2G and 3G networks. In others, carriers are in the process of shutting down these networks.


That might have something to do with a carrier's decision not to display choices lower than 4G. What point would there be in forcing, say, 3G-only connections if the result was always "No signal"?
