I'm from that same area  near Nyon - several calls today.

do you live in switzerland ? I'm from Nyon VD

same here, several calls in Nyon in the last few days.

since the 026588* range has not been allocated to anyone by ofcom it's obviously a fake number...

I got several calls from this number and always just quitting and I think it's a robber tryin to know when I'm at home or not.
