Arrived in Guernsey and cannot get any mobile network connection. Phone frequently displays the message "Refreshing SIM data". Settings, connections, mobile networks, network operators is set to Select automatically. If I tap this, it eventually displays a list of networks to choose explicitly but whichever one I choose, I get the message "your SIM card does not allow a connection to this network".
I ensured roaming was enabled before leaving the UK but I can no longer get into that bit of my account settings to double check.
