Thanks for the reply.
Sorry, stuck in hotel room and dictating my post into Samsung Android phone via "OK Google" thing, so text not very concise.
Mine was okay-ish, but my wife's phone kept insisting upon Java to use WhatsApp.
I'm home now, but did finally communicate with my son's American phone - he was in UK - and worked quite well on mine.
See my comment about LHR hotels on JB.
