When iOS 12.4.1 was released in August, I soon thought that was the end of my iPhone 6 being supported, and here we are, being given 12.4.4 yesterday.
This is the same iPhone 6 on 12.4.3 at a comfortable speed on VPN-boosted Verizon the other day. It looks like my upgrade can wait until September 2020.
I'm talking about hardware support for various radio frequency bands, not iOS software. The iPhone 6 supports all the main LTE bands Verizon uses except one. Verizon uses bands 2, 4, 5, 13, and 66. The Verizon iPhone 6 (model A1549) doesn't support band 66. But that may or may not be an issue in your particular case. They do use 66 to augment coverage so it might be deployed on the particular tower you were concerned with.
My example of the iPhone SE (which supports LTE bands
1, 2, 3, 4, 5, 8, 12, 13, 17, 18, 19, 20, 25, 26, 29) is that T-mobile has recently deployed 600 MHz coverage (in the old UHF TV frequencies, actually). This is referred to as LTE Band 71 - so my friend would get minimal T-mobile coverage here in Maine, for example, where Tmo has deployed Band 71 extensively.
