Overlanding essentials for the miles with no signal
This page covers what to carry on road trips and overlanding routes with no signal, where a device that answers offline fits, and why it does not take the place of a paper map or a satellite messenger.

What should I carry on a road trip with no cell service?
Ready.gov lists jumper cables, flares or a reflective triangle, an ice scraper, a car phone charger, a blanket, a map, and sand or cat litter for traction. The National Weather Service adds a flashlight, a first aid kit, a compass and road maps.
| Item | Listed by |
|---|---|
| Jumper cables, flares or a reflective triangle, ice scraper | Ready.gov. (Ready.gov) |
| Car phone charger, blanket, map | Ready.gov. (Ready.gov) |
| Sand or cat litter for traction | Ready.gov and the National Weather Service. (Ready.gov) (NWS) |
| Flashlight with extra batteries, first aid kit, shovel, tow rope | National Weather Service. (NWS) |
| Compass and road maps | National Weather Service, which adds: do not depend on mobile devices with limited battery life. (NWS) |
Ready.gov also says to keep a kit of supplies in the car in case you are stranded. (Ready.gov) The National Park Service says to tell someone your plan and bring a physical map as a backup. (NPS)
How much of the road has no cell signal?
More than people expect. Providers report 5G at 35/3 Mbps along about 69% of U.S. road miles and about 60% of rural road miles. That is a provider-reported, outdoor figure. Real coverage in a canyon or on a forest road is often worse.

The National Park Service says plainly that you may not have service in the park. (NPS)
Does GPS work without cell service?
Yes. A GPS receiver works out its position from satellite signals, with no cell service. But GPS gives a position, not a map. OffGridOne has an offline map on the device, so it can show where you are.
GPS.gov says the receiver uses signals from the satellites to calculate its three-dimensional position and time. (GPS.gov) It also says GPS satellites provide location signals, not maps. (GPS.gov)
The device has a GPS receiver and also reads GLONASS, BeiDou and Galileo, per OUKITEL. (OUKITEL spec sheet) The device has an offline world map with street-level regions. More country packs are in the Store. See what is inside. Read the full answer in does GPS work without cell service.
What should I do if my vehicle is stuck or I am stranded?
Stay with the vehicle, make it easy to see, and wait for help. Tell someone your route before you go. Never drive into flood water: twelve inches of rushing water can carry away most cars. If you can reach 911, call.
Before you go
Let someone know where you are going and what route you will take, so they know where to start a search. (NWS)
Be seen
Tie a bright cloth to the antenna. Raise the hood after the snow stops. (NWS)
Near water, turn around
Six inches of fast-moving flood water can knock over an adult. It is never safe to drive or walk into flood water. Do not drive around barriers. (NWS)
Where does a device that answers offline fit in the vehicle?
It lives in the glovebox or the go box. Past the last bar of signal, you ask it about a flat, a first aid step or a stuck vehicle, and it answers on the device. It adds to the kit and replaces nothing in it.
- Power. 10,000 mAh, per OUKITEL. In TechRadar's test it ran 25 hours 13 minutes of continuous use. (OUKITEL spec sheet) (TechRadar review)
- Built for the trail. Rated IP68 and IP69K, rated to MIL-STD-810H, and OUKITEL says it withstands 1.5 m drops. (OUKITEL spec sheet) (OUKITEL product page)
- Temperature range. -4 F to 131 F, per OUKITEL. (OUKITEL spec sheet)
- Light. An LED flashlight, per OUKITEL. The Camera app has a steady light too. (OUKITEL spec sheet)
- Size. 7.24 x 3.43 x 0.59 in, per OUKITEL (OUKITEL spec sheet), and 14 oz (396 g) as weighed by DeviceSpecifications (DeviceSpecifications review). Big and heavy.
Answers take time. How fast it answers: 24 to 57 seconds, measured on a development unit on November 11, 2026. It is a reference, not a mechanic and not a doctor.
When is a satellite messenger the better buy?
When you travel far from help and need to send a message. OffGridOne is not a way to call for help, and it has no satellite messaging. A satellite messenger or a phone with satellite SOS can reach people. This device answers questions.
| Job | Better tool |
|---|---|
| Send a message or call for help | A satellite messenger, or a phone with satellite SOS. Apple says Emergency SOS via satellite works on iPhone 14 or later, outside with a clear view of the sky, and is included for two years after activation. (Apple) |
| Know the route | A paper map and compass. (NPS) |
| Call for help in the backcountry | The National Park Service says to consider a personal locator beacon. (NPS) |
| Ask a question with no signal, such as a first aid step or a stuck vehicle | OffGridOne, beside the tools above |

Questions people ask
Can I use it to call for help?
No. OffGridOne is a reference, not a way to call for help. It has no satellite messaging.
If reaching other people matters most, a satellite messenger or a working phone is the better buy. See how the two compare. If you can reach 911, call.
Does GPS work with no cell service?
Yes. A phone’s GPS receiver gets its position from satellite signals, which do not need cell service or internet.(GPS.gov) OffGridOne also has offline maps on the device, so you can see where you are.
If GPS is not available, it shows a best-known position with an uncertainty circle, and can give a rough fix from the stars or the sun, good to about 100 to 300 km. That is a fallback. A paper map is still the backup.(NPS) Read the GPS guide.
How do I charge it when the power is out?
It charges over USB-C at up to 33 W, per OUKITEL, so a power bank or a car charger with a USB-C output can charge it.(OUKITEL spec sheet)
If you charge a phone in a car, keep the car somewhere well ventilated, not in a closed garage, to avoid carbon monoxide poisoning.(FEMA comm plan)
