At speeds that are theoretically 20 times faster than 4G, 5G’s main selling point is definitely its speed.
Apple says that iPhone 12 users can, in ideal conditions, expect download speeds that are twice as fast as what you'd get with 4G: 4 Gbps with 5G and 2 Gbps with 4G LTE.
However, there are three types of 5G that are available to you depending on where you are and who your provider is: low-band, mid-band, and mmWave. The one you use determines the speed and coverage you receive.
