Hi @trotter and welcome to the Community!
Are any of those areas 5G only? Or, is 4G LTE also present? My understanding is T-Mobile’s current 5G implementation is not a whole lot faster than 4G LTE much as initial implementations of 4G LTE were barely faster (and sometimes slower) than then existing 3.5G technologies. In fact, part of the reason 4G LTE is used as a term rather than merely 4G is T-Mobile and others branded by marketing fiat then existing 3.5G technologies as 4G, so needed to use 4G LTE to differentiate real 4G.
Though T-Mobile’s acquisition of Sprint is now complete, it will be until at least year end 2021 before those disparate networks are fully integrated.
I believe it should be kept in mind Republic does not own a cellular network. Rather, Republic provides cellular coverage via its network partners. Republic’s current partners are T-Mobile and the now T-Mobile owned Sprint. Republic’s plans for a 5G future will largely depend upon on how its current network partner and/or potential future network partners evolve 5G. Please don’t read much into the mention of potential future network partners. It’s merely an acknowledgement of theoretical possibility on my part. I have no inside information regarding any plans Republic may or may not have regarding how its network partnerships may or may not evolve.
The other variable is availability of 5G capable phones at a “reasonable” price. There’s currently a dearth of those as indicated in this recent article from Tom’s Guide:
Of the phones referenced there, Republic does support U.S. factory unlocked variants of Samsung’s Galaxy S20, S20+ and S20 Ultra. Though Republic does not currently support Apple’s iPhone outside of a closed invitation only beta, I think it’s worth mentioning Apple does not yet have a 5G iPhone though that will change this fall with the iPhone 12 series. Some think Apple knows some things about the U.S. mobile phone market and Apple hasn’t been in a particular hurry to bring a 5G iPhone to market.
The above provides context for why I mostly stand by my comment that 5G is currently more marketing talking point than reality. That will, of course, be changing, however, it remains my opinion, we’ll be talking 2021-2022 before 5G will have meaningful broad based market penetration. If my phone were in desperate need of replacement, I wouldn’t be overly concerned with 5G just yet but that’s me.
