Yeah, at least in the US T-Mobile already has 5G deployed in most of their network footprint and AT&T and Verizon are quickly playing catch-up.

T-Mobile has been playing this game like "fasted LTE in the US", "fasted LTE in US cities" for almost 10 years..

Ironically T-Mobile employees working in their Factoria HQ cannot get T-Mobile reception near their homes in Sammamish.

The US (and friends) are quite a long way behind because they refused to use Huawei 5G equipment.

Huawei was market leader by 1+ year, so countries which have used Huawei are mostly fully deployed already.

The usage of a 5g capable phone may also require an "upgrade" to a 5g capable plan. The major upgrade at the moment is paying more money. If it is 1 phone, then it is not that big a deal, but the cost value is not there with an (extended) family plan of 6 phones.

I use verizon prepaid, my plan is 5 gigs for 25 a month (which is plenty of data for me and a really decent rate rivaling walmart-type plans), and I just upgraded to the TCL 10 5G UW phone which cost me <$300. Runs like a dream, competitive with phones that cost double that.

Postpaid is basically a scam, the plans are just more expensive AND you're on the hook for X amount of years, in exchange for small upfront savings on a phone (but not even in all cases).

2 networks have 5G in my city, my network has no immediate plans to introduce 5G here.

Yes, they have some towers. Acording to wikipedia, the standard is not finalized.
