The millimeter wave bands for 5G are unlikely to be deployed here anytime in the near-to-middling future. As mentioned in another comment, 3G networks will start being phased out starting at the end of the year. 5G will subsume the the existing 3G/4G bands and make use of the new 3.7GHz band. The new coding/spectrum use formats will make more efficient use of the available bands. Much of 5G will exist there.

The new millimeter wave bands have very limited coverage, will require between 5 and 20 times the number of cell sites to provide similar coverage realized on the lower bands, and a lot of optical fiber to connect them all together. That makes sense in urban areas and thickly settled suburbs, but not out here. The customer density is a money loser.
