Hi I am currently in the USA and once again am unable to get any 4G connection - it is not only the USA but European countries I have visited in the past couple of years - it is very frustrating as when I leave anywhere with a Wi-Fi connection I lose the connection - I rely on Maps when driving in the USA which of course I cannot access. I use an IPHONE 11 but this also happened on my old Samsung phone when I was with Virgin making me switch to 3 but it is still happening - have tried all the tips including switch on an off flight mode but nothing is working
