Most 3g towers will be replaced with 4g and 5g so it should be similar (or better in throughput) but some phones will have issues in band support. My phone is missing one of the popular 4g bands, for example, so that may impact rural coverage in particular.

Doesn’t 4G and 5G also have a shorter range?
You don’t just need to replace 3G towers, you likely need to add more towers.
