We’ve been hearing about 5G for ages, and 2020 is the year it’ll finally become a reality for some people. Until this point there have been a few sparse 5G networks available in cities, but with only a handful of phones supporting 5G, even if you lived in an area with coverage odds are you couldn’t connect. That’s all set to change with a host of new 5G phones expected to be announced through 2020, and providers all around the world starting to switch on additional 5G towers.

Even so, it’s hard to know what to expect from 5G. Depending on your provider and your network, you may get blazing fast speeds but only in certain places, a bump in reliability without much speed, or anything in between. It turns out 5G isn’t really one thing, it’s a collection of technology and new frequency bands, and different carriers are focusing on different aspects of the network.
