I'm on an Irish sky account. I flew into Paris on Saturday 12 September and both phone and data worked on arrival. Today, I could make calls but there was no data available. Roaming is enabled on my Xiaomi redmi 13 5g. I haven't changed any settings since arriving.
A little later....
It seems that roaming only works on the "free-sky" network . If my phone itself automatically chooses a different network (,orange, bouygues), then I lose data. Also, there doesn't appear to be any 5g available even though Paris is well covered by 5g networks.
