Probably because GPS soaks up power. So it isn't turned on unless some app
explicitly asks for it.
Remember that one of Android's main design principles is to minimise power
consumption.
A simple, free, app such as "GPS Status & Toolbox"
(
https://play.google.com/store/apps/details?id=com.eclipsim.gpsstatus2), or its
equivalents, will tell you basic GPS info such as Lat/Long, number of
satellites fixed, etc. Note that Android will turn off GPS as soon as you
switch away to a different app (that's just how Android works). If you want to
keep the GPS active then use an app that explicitly tells Android "keep the GPS
on in the background" -- the only ones I know of are apps with the ability to
do tracking, such as "GPS Essentials"
(
https://play.google.com/store/apps/details?id=com.mictale.gpsessentials) which
provides a bunch of mapping-related stuff on top of basic GPS data.

Tough! You can't.

Because for most people that's true. It's not true for me (2 devices without
SIM slot, 1 with it but not occupied, 1 with SIM installed) and apparently not
for you either. But we're in the minority.

Sigh... Yes. Of course.

Android itself is perfectly capable of doing that, and actually does so. There
are many lazily written apps, though, that don't use that kind of information
and some of the "system" apps on your device may well be among them.

Makes sense. Google maps requires that you agree to give location info /to
Google/, and if you don't agree then it won't run. (Actually I'm not sure that
it won't run at all, but it certainly won't show your current location.)

Yes. Search the archives of this group, sometimes it seems we talk about
little else (that and US politics).
Or maybe someone else will recommend something. What part of the world do you
want maps of (it makes a big difference) ?

Now that is somewhat different. Many (probably all)
mapping/tracking/navigation apps will run offline (but perhaps with reduced
functionality). And all of them (as far as I know) will allow you to download
a fairly large amount of map data to the phone (word used deliberately since
that the important market as the app-vendors see it). However "phones" are
limited in storage, and some mapping data goes stale fairly fast, so most of
them (again, as far as I know) will only download somewhat limited data (maybe
a GB or two, max). I can't comment on /what/ data is included, since the only
apps I have use Google Maps data (shops, etc, are only available online as far
as I know), OSM (no data at all about shops etc), and the UK Ordinance Survey
maps (which are basically the 1:25000 maps of GB, and so include landscape
features but would scorn to include street names let alone shops). Other apps
are provided by what you might call "map vendors", where the app itself is
unimportant and its the actual map that you're buying. I haven't used any of
those, but it sounds as if they would be more what you are looking for. I
imagine that all of them can be used offline, but I also imagine that all of
them will have reduced functionality in that mode.
