Apart from anything else, this is about wifi coverage which is for data
which is little used for voice calls.

Never used Whats App voice calls, grandad?

No, nor Skype on my mobile, as it happens. Do you know the volumes?

I did say little used not unused.

Every little helps [tm].

I've taken to using Whats-App voice when the person I'm calling is in a
GSM not-spot, but has wifi coverage.
