Nope. My work 6S on Verizon is slower and less reliable than my 12 Pro on Verizon.Sad to see most of y’all are still having service issues. No way it’s the phones, it’s the service in the area YOU live. For me it was Verizon that was weak and ATT is strong, I’m getting 5Ge in a lot of places Verizon wasn’t getting any service. Now you drive 100 miles and the roles might be reversed. Check your carriers, switch to a stronger provider in your area if you can. Marginal service is a thing and I was lucky enough to get out of mine.
I’ve proven it to apple engineering running tests with the phones side by side. Still no resolution.
