Question

No 4G Coverage during data roaming - 5G works

Hi!

I have been having issues for the past few months.
Whenever I am in the UK, 4G and 5G work fine - but when I go abroad to Germany, only 5G works and 4G doesn’t. My phone automatically chooses O2 and I don’t have the option to choose a different provider. It goes so far that I can receive text messages, but I cannot make or receive calls and when I try to send whatsapp messages, they don’t get delivered.

Any ideas what I can do?
