    BTW, 600mhz isn't "5g" as it's not millimeter RF, or high enough speed to qualify as "faster" than 4G LTE.

    600mhz 5G is a fallback band for 5g to provide coverage in the gaps between millimeter wave towers - and it will be easiest to outfit existing on existing towers, but it's not any faster than 4G LTE can be with the same investment in bandwidth or coverage.

    "Millimeter waves are electromagnetic (radio) waves typically defined to lie within the frequency range of 30–300 GHz. The microwave band is just below the millimeter-wave band and is typically defined to cover the 3–30-GHz range."

    I've had 125mbit-140mbit 4G LTE many times, so this "5g" ain't nothing to get excited about, and IMHO isn't 5g.

    Just got my new 4g device and it is somewhat slower than 3G sometimes. Max speed is 42Mbps with -89dBm or 1Mbps on -100dBm.
    When I went to my hometown the speed was 80Mbps w/o CA.
    I feel 5G w/ more mini-towers will penetrate nook and crannies of a city/town or rural area.

    Right now indoors I am getting 116Mbs download and 16.1Mbits upload. It varies depending on location and time of day as well.

    Hopefully the 5G rollout will bring with it expanded backbone bandwidth along with higher base throughput via 600mhz 5G + much higher throughput on millimeter coverage areas.

    Have you upgraded your S7 Edge? My dad's S7 is a Exynos version and signal drops when you're at the edge and always falls back to 2g instantly!

    I upgraded a few months ago to a Samsung Note 10+, but I was getting similar speeds as on the S10+ when I retired the S7 Edge - I traded the S7 Edge in for a nice credit + trade-in bonus. I miss it, but the Note 10+ is nice too.

    None of my phones has fallen back to 2G for a long long time...
