When I got my Pixel, my wife took my old Nexus 6 to replace her failing Moto V3. We got a correct size SIM card and ran with it.
I found that I had to set the phone to "3G Only" to get it to work decently with her old PAYGo plan. This isn't a problem, since her plan has no data.
But, are there different APNs that the phone should have for a plan of this sort, or is setting the phone to 3G just what needs to be done for a phone that has features that the plan doesn't use?

When network type was set for "LTE (preferred)" it connected, but with marginal indicated signal strength. When out in the wilds of west-central Minnesota, connections were intermittent (band 2 region). Switching to "3G" gave an indicated stronger signal, and my wife reported more reliable connections. I realize that the number of "bars" on the signal strength meter doesn't mean anything specific, but I see 1 or 2 bars in LTE mode and 4 or 5 when switching to 3G.
However, I've since discovered that the radio in the Nexus 6 doesn't have nearly as sensitive a receiver as my new Pixel, so the problem is probably just with the phone.
SInce the plan has no data allotment, switching to 3G doesn't cost anything and seems to help a lot.
