I am having problems getting my Samsung S9 to connect to a network whilst roaming abroad.It will not connect automatic or manual, I get a message Your sim card does not allow connection to this service. I've have set roaming to on and international call bar is off. I even contacted virgin before I went away as the last time I was abroad I couldn't connect. They set it up for me, but, no I still can't connect. So here I am on holiday with no connection again. Wifi is ok. Can anyone help with this, please.
