No signal?
Still connected.
Up to 10 km device to device without a network, one-press SOS, and a 10000 mAh battery. No SIM, no monthly fee.
Trails, coastlines and disaster zones are where the signal ends. LoraSecrt keeps your group talking after it does.
One app. Two ways to reach your people.
LoraSecrt pairs with your phone over Bluetooth. The app picks the channel for you, based on whether the device is connected.
With network
Messages go to friends in real time over the phone network, and the map shows your phone's current location.
Device not connected: online channel first
Without network
Messages travel over LoRa, point to point between LoraSecrt devices within range. Your position comes from the device, and you see nearby users who carry one.
Device connected: device channel first
Switching is automatic. Connect the device and messages go device to device; disconnect it and they go back over the cellular network. No SIM, no monthly fee.
SOS emergency help
Three seconds to call for help.
Hold Vol+ and Vol- for 3 s
Or, with the device connected, long-press the Bluetooth icon at the top of the app home page.
It sends your ID and position
The device sends its ID with latitude and longitude. The positioning, data and status lights flash together.
Friends and nearby devices receive it
They get the SOS message and can see the latitude and longitude it was sent from.
Hold Vol+ and Vol- for 3 s again to exit SOS mode.
International distress light signal
Hold the lighting button for 3 s and the lamp flashes the international distress signal. Press it again to turn it off.
Use SOS only in genuine emergencies. Make sure the antenna is installed and the battery is sufficiently charged.
A messenger, a power bank, a lamp and a radio.
Keep chatting with no signal.
Send text and voice messages to friends or a group. The Public Board collects broadcasts from everyone nearby when you are offline outdoors, and you can add a nearby user straight from the map, with no network.

Questions

Yes. When the device is connected to your phone, messages go device to device over LoRa first. When it is not connected, the app sends and receives over the cellular network. Switching is automatic.
Hold Vol+ and Vol- together for 3 seconds, or long-press the Bluetooth icon at the top of the app home page while the device is connected. It sends the device ID, latitude and longitude to friends and nearby devices, and the three indicator lights flash together. Hold both keys 3 seconds again to exit. Use SOS only in genuine emergencies, with the antenna installed and enough battery.
Up to 10 km point to point without a network, in a clear open area with the antenna at 2.5 m. Obstacles, testing close to the ground, the seaside, humidity, interference and nearby metal all shorten the range.
No. The solar panel (max 1.5 W) is for temporary emergency power storage only; face it directly at the sun. For everyday charging use Type-C input (max 22.5 W).
Yes, over Type-C (single port max 20 W) or the magnetic wireless charging area (max 10 W). Used together they share 20 W. The USB-A port (max 1 W) only powers small appliances such as fans and desk lamps and is not for charging.
No. Do not use it during thunderstorms: the external antenna can attract lightning, which may cause injury or damage. Also keep metal away from the antenna and do not keep the device in a metal case, as that severely weakens the signal.
