5G is shocking in Cardiff on Vodafone. Can barely get any data in Canton with phone showing 5G. I also find I can be connected to 5G, do a speed test and get decent numbers but no actual internet.
A friend of mine was with me one time and they had an EE connected phone and he was getting great speeds and data transfer while mine couldn't load a page.
I find if I'm listening to the radio on the phone and the signal changes to 5G I get disconnected.
If it drops to 3G I lose connection as well.
I'm considering dropping vodafone when my contract is next up as it's so frustrating, and I've been with them for years and years
