A:Answer From my research, the difference is in the type of cellular (5g) wave. Superfast 5g uses the 5mm waves, fast (or regular 5g, which is classified as fast because it’s faster than 4g) uses sub6GHz. Google can explain it better than I can. Google what is the difference between 5g and super fast 5g. The iPhone SE 3rd generation, aka iPhone SE 2022, has 5g capability, but not the 5gmm.
Some cellular companies are focusing more on the 5gmm type waves (Verizon,AT&T). TMobile has mentioned they want to expand all 5g wave types, not just the 5gmm, while right now the other cell providers are focusing on the 5gmm. The 5gmm wave is not realistic in many rural areas, and is more likely to be found in cities, or crowded areas like airports, ballparks etc. Only time will tell which direction these big name cellular providers ultimately decide to go in terms of which type of 5g wave they build and use (or whether they use both).
In my opinion, at least this early on the 5g game, you can’t go wrong with any 5g phone, and especially since the technology is ever evolving, you may be better off getting a cheaper phone in case you may want to upgrade in the future, whether primary for 5g purposes or a phone with new features etc .
