Couldnt you try phoning one of the numbers on the phone...say the most recently used one?
They might also have an ICE number listed... for emergencies.

Ah, as ever, as wise as you are beauteous - hang on, I said that a year ago and you still couldn't remember my name!

But I did think of that, after my hangover cleared, but phone is dead, no charger fits, and I don't trust myslf to start levering panels off to try and put sim in another phone!
Luckily I'm seeing mr JPC himself at the weekend. Either him or senior granddaughter will no doubt sort it out in a jiffy!
Personally, I think the old tin can and lengths of string were a lot less trouble.
That reminds me, I think my Luddite membership is about to run out.......................
