I have recently returned from travelling in Austria and Hungary and was unable to use data at any time. My phone settings were set to roaming. I was regularly showing 5 bars of 5g reception with R being displayed. I tried switching from airplane mode and back, changed service providers, rebooted the phone several times, but nothing worked. I had to rely on WiFi the whole time. Now I'm back in the UK everything is working normally. Does anyone have any ideas?
