The 5G wireless revolution may finally be arriving soon, and one smartphone-maker has come up with a way to make today's 4G phone upgradeable to the new high-speed network when it finally turns on.

It's been several years since 4G LTE wireless networks began to roll out in North America, and soon after that big speed and bandwidth upgrade we were already being promised next-generation 5G networks.

Now it's 2018 and 4G is beginning to seem a little sluggish in our increasingly wireless world but fortunately we finally have some launch dates for 5G. AT&T has said it will start off with 5G in a handful of cities by the end of 2018, while Verizon will start in Houston this year and Sprint and T-Mobile are looking to speed things up in 2019.

Meanwhile, Motorola is launching its new Moto Z3 Android phone this month on Verizon's huge 4G LTE network with one interesting bonus: it will be fully upgradeable to the carrier's 5G network when it launches next year by simply purchasing Moto's 5G "mod."

Mods are exactly what they sound like; modular attachments that snap on to the back of a Moto Z phone, adding a better camera, or speaker, or even a tiny photo printer or projector. The latest Motorola mod will add 5G and be available sometime in early 2019, although Motorola has not yet revealed pricing for the upgrade.

The Moto Z3, however, is going on sale August 16 with a retail price of $480. So if you're going to be in the market for a phone before 5G officially launches, it's currently one of few options out there to get your phone now and ensure it can handle next gen speed when it turns on.

But if you can wait for that new phone until 5G is here, there's sure to be many more options to choose from.
