You can get WiFi in a car three ways: a built-in hotspot with a carrier plan, a portable hotspot device, or phone tethering.
Getting a reliable internet connection on the road used to mean flipping through paper maps. These days, passengers expect streaming, navigation updates, and mobile work to work as well in the back seat as they do at home. The right solution depends on your car’s age, your phone plan, and how many devices need a connection. Most drivers find that one of three routes fits their situation, and knowing which one matches your car is the difference between a quick setup and a wasted afternoon.
Whether you want an always-on connection for a family road trip or just a way to keep the kids’ tablets busy, here’s what actually works.
Three Ways to Get WiFi in a Car
Every method of getting internet in a vehicle falls into one of three categories. Here’s how they compare:
| Method | What It Costs | Best For |
|---|---|---|
| Built-in vehicle hotspot | $10–$25/month plus eligible plan | Newer cars with factory hardware |
| Portable hotspot device | $50–$200 device plus data plan | Older cars, multiple devices, travel |
| Phone tethering | Usually included in your existing plan | Quick setups, one or two devices |
Built-in hotspots come with new cars from brands like Kia, Nissan, Volkswagen, and GM, but they require activation and a data plan. Portable hotspot devices work in any car with a power outlet and often support more connections. Phone tethering costs nothing extra on most plans and takes under two minutes to set up.
Built-in Hotspots and Carrier Plans
Many automakers now offer factory-installed WiFi hotspots that turn your car into a rolling access point. These require a compatible trim level and an ongoing data plan, usually sold through a wireless carrier.
AT&T sells its Connected Car plan for $15/month with an eligible unlimited wireless plan, and Verizon offers a similar in-vehicle hotspot add-on tied to its connected-car program. Volkswagen lets current Verizon and T-Mobile customers add a monthly hotspot subscription, while compatible Metro by T-Mobile plans cover the U.S., Alaska, Hawaii, and Puerto Rico, plus 5GB in Canada and Mexico.
Most manufacturers bundle a free trial. Nissan includes a 1-year trial with up to 2GB/month on select new 2026 models in the Premium Package, and older models get 3GB or 90 days. Kia’s hotspot, powered by Verizon, offers 3 months or 3GB on eligible 2022-and-newer vehicles, and OnStar provides up to 3 months of unlimited hotspot data on qualifying Chevrolet, Buick, and GMC models. Setup happens through the car’s touchscreen or the manufacturer’s app, and activation takes about ten minutes.
Check your car’s trim level before assuming it has the hardware. Many base models skip the hotspot module entirely. If your car has it, the infotainment settings menu lists a WiFi or hotspot option where you activate the service and see the network name and password.
If your current car lacks built-in WiFi but you want a permanent setup, a dedicated automotive wifi router designed for vehicles plugs into the power outlet and provides a stronger signal for more devices than most factory systems.
How to Tether Your Phone to the Car
Phone tethering turns your phone’s cellular connection into a WiFi network the car can join. It works on most modern phones and cars, provided your carrier plan includes hotspot data and the car supports WiFi connections. Volvo and Polestar both note that the phone and carrier must support tethering and that the subscription must include data.
Follow these steps on your phone and car’s touchscreen:
- On the phone, open Settings, find Personal Hotspot or Mobile Hotspot, and toggle it on. Confirm your plan allows tethering.
- In the car, open the Settings menu and select Internet or WiFi Connections.
- Choose WiFi or your phone’s network name from the list of available networks.
- Enter the password shown on your phone’s hotspot screen, then press Connect or OK.
- If the car was using another connection source, confirm the switch in the same menu.
Once connected, the car’s screen displays the WiFi icon, confirming the link. Tethering drains battery faster than normal use, so plug the phone into a charger while driving.
What to Check Before You Commit
Compatibility is the most common pitfall. Some carrier programs only work with specific brands. Kia’s hotspot only functions in the fifty states and D.C., and it may be unavailable for 2022-and-newer vehicles sold in Massachusetts. Nissan’s hotspot supports up to seven WiFi-enabled devices at once on qualifying models, but older trims may only handle three or four.
Location limits matter too. A hotspot that works in Ohio may not work in Ontario. Verify your coverage area before paying for a plan, and read the fine print on state restrictions.
One more distinction worth understanding: the car’s WiFi hotspot is not the same as its cellular data service. The hotspot uses a separate data allowance that draws from your plan’s hotspot bucket, not the same pool as your phone’s normal browsing. If your plan has no hotspot data, tethering won’t work no matter what the car supports.
