Had no No Data or Calls/Texts!!!! when Roaming in Ireland (3 trips) or Italy (Venice - 1 trip), Germany (1 trip) or Switzerland (1 trip).
Utterly disappointed as roaming was on, but nothing was available and I was extremely inconvenienced as a result.
UK is still in the EU, but the messages I was getting that I was outside of the EU!! Even Giffgaff do not do this to their customers. Going back to them. Full stop.
In addition, poor coverage in Cheshire, where I work and am constantly out of reach 9-5 Mon-Fri.
It's hard to grasp, how I could stay with ID for that long! (Mar - Sept!)
