I have been in Italy for 3 days and have had no phone signal or mobile data.
Roaming is set up, but when I switch my phone on it seems to give me a 4G signal which lasts about 5 minutes then nothing. I have a dual sim phone and have a back up sim with O2 which works perfectly so its not the phone.
I get a message when trying select a network automatically or manually " Could not connect to Network now. Please try later"
