That's pretty much what I thought the case would be. I'm sure T-mobile now being owned by Orange will undoubtedly improve their signal performance.
But my colleague an I are on O2 and Vod and between us, by the sounds of it, we should be able to call home : ). Although my original question was driven by my need to have some sort of emergency line should anything go wrong. Not got the luxury of a sat phone just yet
and I could probably forgo checking in at home or the office for a week
