The SIM card is to validate you have a valid account with a GSM provider
so you can use their cellular service. All cellular provides must
support 911 calls even if you don't have a currently active subscription
with them. That means you can make 911 calls without a cell plan.

So I would think even without a SIM card in a GSM phone that the cell
carrier cannot refuse to accept a 911 call to their network. They
cannot require you be their subscriber for you to make a 911 call.
You could buy a new battery; however, for the cost, you can probably get
a cheap flip phone just for 911 calls. If you don't have a cell plan,
you won't have a phone number to give to the emergency operator to call
you back in case of a disconnection or to have the police or ambulance
call you if they cannot find you. With a cell phone without location
services, how are you going to make a 911 call in the "wilds" (assuming
you get a signal and can make the call) to tell them where you are (if
you have a clue) but you cannot speak? You might manage to dial 911 but
too injured to speak.
Without a cell plan, and with a phone that has no GPS service, how are
you going to tell anyone where you are? "Help me. I'm lost and injured
in the middle of some woods. No, not a clue where I am. Can't help you
find me." Better is to write down a trek schedule of when you leave,
where you will be, where you will go, and when you expect to get back,
just like how flight plans work. If "wilds" means you will still be on
roads (so not that wild), you go hiking for a couple miles looking for a
mile marker and tell the emergency operator about where you are (and
hopefully you know what road you are on or you happen to also see a road
sign for it on your hike).
When someone says "wilds", I don't imagine a scenario where there is
handy location signage. When the cell carriers claim 99% coverage of a
country's population, that 99% is scoped to within the regions they
actually cover. If you're in the "wilds", you make get no cell signal.
If you look at the cell carrier coverage maps, that are still huge
chunks of the USA that are *not* covered. Population density is so low
there that who are there are not included in that 99% coverage
statistic.
If you have a cell plan but are in an area with a signal too weak to
establish a phone call, your cell phone may still connect to the nearest
tower. This will leave a trail of where you were (as you make
consecutive phone calls). Emergency personell can use this trail from
your cell provider to search for you albeit the area may be large. Of
course, that means someone has to report you missing which is why I
mentioned having a flight plan you give to someone who will initiate a
missing person search if you don't return or show up at a different
destination.
If you cannot afford cell phone service, there are assistance plans to
give you a free phone (but you could buy your own or maybe reuse your
old one to use instead of the itty bitty low-featured one they give
you). One is Assurance Wireless. Tracfone has one called SafeLink
Wireless. Those are the only 2 that I've heard of. There may be
others.
If you're going to be in the wilds for awhile, where are you going to
recharge your cell phone? Are you planning on toting along a fully
charged power pack and a big one so you can get enough recharges to
outlast your trek into the wilds?
