3G speed plans are throttled LTE, they are not running on the actual 3G network.
You will get quick response as the latency is lower on LTE, but you may get quicker overall speeds on the actual 3G network if you choose to force the 3G connection on your device.
As per ShawnC13:
don't see 4G plans being offered in the near future. They have spent the last 2 years getting away from them and aligning themselves with the other 3rd Tier providers. I guess 4G will come back once all the other tiers are on 5G.
