Welcome to Vodafone Community
I posted last year around the fact I was a little grumpy that Apple had released 5G devices that didn't
On their own website, they insinuated it was a case of it being down to the carriers (I challenged this as Vodafone have offered 5G roaming since 2019).
It turns out that didn't matter as since then, I've been nowhere so would never have known unless it had been pointed out.
This has been fixed with the arrival of iOS 14.5
The new iOS 14.5 gives us:
Support for 5G when using dual sim mode and
5G international roaming
