I have a Hong Kong variant of the iPhone with dual sim slots, and now both sims have 5G data. I no longer have to disable one in the settings to make 5G work. Super nice!
Also, I got the WatchOS beta and I gotta say the watch unlock works like a charm. Getting into the phone is no longer something I have to think about it, which is amazing. You know it’s a great feature when after a day it seems like you forget how it ever used to be before it haha.
