BT include wi-fi access to their customers' routers, which means
you can get wi-fi in many places, including some where there is
no mobile coverage. They also provide an app with which you can
make voice calls over wi-fi, billed at your land line rate.
Plusnet don't provide either of these, or didn't last time I
looked. Obviously you may or may not value these
features!


Why would anyone want the second one?
