  1. I don’t care about 5G at all. What I would like for them to do is fix 4G everywhere before they turn 3G off. 75% of the time when I drive outside of urban areas (in USA) all I get is 3G service.

    Honestly I see zero reason to spend a dime on 5G as a consumer.

    1. Luckily all it takes in US to roll out 5G is a firmware update on the handsets… So they can sunset 3G without actually doing so.
