The short answer
No, not for location sharing. Life360 needs an internet
connection - mobile data or Wi-Fi - to share and receive
locations. When your phone has neither, meaning no signal and
no internet, Life360 can't update your location with your
Circle, so the people in your Circle only see your last known
position. Nelos is built for that gap: connect your phone to a
small radio and your family sees each other's location on a
shared map, with no internet or mobile data needed. You can
start using it for free.
Your phone can still work out where it is using its GNSS
receiver. But "the phone knowing its own location" and "the
phone getting that location to other people" are two separate
things, and only the second one breaks when you lose signal.
What Life360 needs to update a location
Life360 works the way most location-sharing apps do. Each
member's phone works out its own coordinates, then shares
those coordinates with the other people in the same Circle
over the internet. When you open the app and see where
everyone is, you're looking at the most recent update each
phone managed to send.
For a single update to go through, two things have to line
up: the phone knows its own location, and there's a working
path to the internet - mobile data or Wi-Fi. Take away the
connection and the chain stops. The phone still calculates
coordinates, but there's no way for those coordinates to
leave the device.
What happens when your phone loses both mobile data and Wi-Fi
In a city, your phone almost always has at least one path to
the internet, so you rarely run into this. On mountain roads,
in forests, in many national parks, or on long highway
stretches between populated areas, both connections can
disappear at the same time.
When that happens, your phone can't send a new location, and
it also doesn't receive new locations from anyone else,
because their phones are usually in the same situation. On the
screens of people still in coverage, your location will be
wherever it last updated before the connection dropped. Many
apps of this kind show a timestamp for that last update
alongside it, but that line is easy to miss, and that's
usually when people start worrying more than they need to.
Signal bars aren't the same as a usable data connection
People see signal bars and assume data still goes through.
Bars only tell you the phone is picking up a signal from a
tower. They say nothing about speed, stability, or whether
that tower will let you push enough data through to finish a
sync. You can have one or two bars and still not load a map or
upload a location. At the edge of coverage this is common.
For location sharing, "has bars" and "can move data" are
worth treating as two different things.
Your phone knows where you are, but that isn't the same as sending it
This is the core point, and where a lot of people get it
wrong.
GNSS - which includes GPS and similar satellite positioning
systems - doesn't depend on an internet connection to work.
The phone receives satellite signals and works out its
position on its own, without using data. That signal can
still be weak or lost in tunnels, indoors, narrow canyons, or
dense forest, but it doesn't need cell service. A smartphone
can use network data to help get a position faster or more
accurately in the first few seconds, but that's assistance,
not a requirement. In other words, even with no signal at
all, the map app on your phone will usually still point to
roughly where you're standing.
But for someone else to see that location, the coordinates
have to travel from your phone to theirs, and that trip needs
a channel. For Life360, that channel is the internet. With no
internet, the coordinates stay on the phone, like a letter
that's been written but has no one to carry it.
To sum up: "the phone knows its own location" is GNSS, and it
doesn't depend on the internet. "The phone can pass that
location to other people" is the connection, and the
connection is what disappears when you leave coverage. Every
location-sharing app that works over the internet hits this
limit, not just Life360. The guide
does GPS work without cell service
goes deeper into why the GPS half of this never needed a
connection.
When your phone gets back online
Things usually recover on their own. When the phone picks up
mobile data or Wi-Fi again, Life360 updates your current
location with your Circle. From the perspective of someone
back home, your position jumps from the old point to the new
one. If you covered a long distance while out of signal, that
jump can be large and won't follow the actual route.
One case is worth noting. If the phone runs out of battery or
is turned off while out of coverage, there are no updates
until it's back on and online. The last position other people
saw is the last update before the phone lost its connection,
and it may be hours old.
If you regularly go into areas with no signal
If a dead zone is an occasional thing, knowing the behavior
above is enough. If your group regularly goes into places
like that, there are a few additional directions. Each one
handles a different part of the problem.
A local SIM or eSIM
Swapping a SIM or adding an eSIM only helps when the problem
is that your carrier has poor coverage in that area but
another carrier has some. If the area has no tower at all, no
SIM changes that. In a lot of mountain and forest areas, this
is the case where there's no infrastructure. The guide on
staying connected abroad
goes into more detail on when swapping a SIM helps and when
it doesn't.
A satellite communication device
Handheld satellite devices connect directly to a satellite
network instead of a ground tower, so they work in many
places with no cell service at all. They're especially useful
when you need to communicate outside the group, or want an
emergency channel that's independent of ground
infrastructure. In return, they usually cost more, for the
device and the service, and need a relatively clear view of
the sky.
A separate communication layer for the group
There's a gap that neither a SIM nor a satellite device is
aimed at: members of a group traveling together, close to
each other, who just want to message and see each other's
location. In that case, the group doesn't need to reach a
distant server; they just need the phones in the group to
reach each other. The guide on
communicating while hiking without cell service
goes deeper into this direction.
Where Nelos fits in
Nelos is a group communication app that uses a small radio. Your
phone connects over Bluetooth to a compatible radio device.
Instead of sending data over the internet, Nelos exchanges the
group's data - messages and locations - over that radio layer.
No cell service, no Wi-Fi, no account or backend server in
between.
For location sharing, this fills exactly the gap above. Each
phone's GNSS receiver still works out its coordinates as
usual. As long as the radios in the group can still reach
each other, Nelos carries those coordinates over LoRa instead
of the internet, and shows each person's most recent shared
position on a preloaded
offline map.
For children or pets who don't carry a phone, a small compatible LoRa tracker can fill the same gap: Nelos asks it for its position over radio, with Find Mode for a search and Safe Zones that alert you when it leaves an area. See kids' GPS trackers without cell service.
A few things to be clear about. This isn't continuous
real-time tracking the way it is with a connection. Range
depends on terrain, hardware, antennas, and radio conditions,
so there's no single number that holds for every trip. Nelos
also isn't a rescue device and doesn't replace a satellite
device when a trip genuinely needs the ability to call for
help. It's a communication layer between members of a group,
for the stretches when the group is out of coverage.
Combine, don't replace
There's no reason to drop Life360. When there's a connection,
it does its job well: it lets people back home see where the
group is and sends a notification when someone arrives. A
sensible setup for a lot of groups is to let the internet
apps handle the connected part, and have a separate layer for
the stretches with no connection.
On a trip, that looks like this. In cities and on the
highway, Life360 runs as normal. When the group turns onto a
mountain road and the signal disappears, they switch to
seeing each other's location through Nelos, as long as the
radios in the group can still reach each other. When they get
back into coverage, the internet apps sync again and
everything is back to normal. The two layers don't conflict;
each covers what the other can't reach.
If you regularly travel in a group into places with no
coverage, Nelos is one way to add a direct communication
layer between members over LoRa. See

hardware you need and how to set up a team.

Frequently asked questions
Does Life360 work without signal or internet?
Not for location sharing. Life360 needs mobile data or Wi-Fi
to update your location with your Circle and receive other
people's locations. Without signal or internet, members of
the Circle only see your last known position.
My phone still has GPS, so why can't others see my location?
Because working out a location and sending a location are two
different things. GNSS lets the phone know where it is
without the internet. But for those coordinates to reach
someone else's phone through Life360, you still need a data
connection.
Can I use Life360 in Airplane Mode?
In Airplane Mode, the GNSS receiver can still work out a
position if location is turned on. But Life360 can only share
that position when Wi-Fi or mobile data is active. Airplane
Mode isn't a way to use Life360 out of coverage.
Does GPS need the internet?
Not to receive satellite signals and calculate a position. A
smartphone can use network data to get a position faster or
more accurately at first, but that's only assistance.
Would switching to an eSIM make Life360 work in the mountains?
Only if the area actually has coverage from a carrier your
current SIM can't reach. If the whole area has no tower,
switching a SIM or eSIM changes nothing.
