But at Mobile World Congress, there was far more buzz about the Samsung Galaxy Fold and Huawei Mate X than about the early 5G devices being shown off. The lack of attention paid to all the 5G phones makes you wonder whether all the racing and chest-beating was truly necessary, and serves as a reminder that the next-generation wireless technology is still in its early days.

Part of the problem is that 5G being "here" doesn't necessarily mean it's here for you. With early coverage being quite sparse, industry experts agree that adoption won't really kick off until late 2019 and into next year.
