WiFi in the car: best options to stay connected while travelling

Rate this post

Having wifi in the car moved from luxury to real need. Between real-time mapsmusic and video for passengers, online classes or meetings while travelling (as passenger, of course) and laptop work tasks, stable Internet inside the vehicle saves time, stress and mobile data. This guide explains all the ways to get WiFi in the car, with clear pros and cons, usage examples and a quick comparison so you pick what best fits your trip. Plus, we’ll show why the combination eSIM + hotspot is today’s most versatile choice.

Both in motorhomes and in family or company cars, a reliable access point lets you connect several devices simultaneously (laptops, tablets, consoles, cameras) without depending on the driver’s tethering or draining their battery. Distractions disappear, navigation improves (live updates and traffic alerts) and, if travelling abroad, you can avoid roaming with an international plan. In short: knowing how to get wifi in the car is no longer optional; it’s now part of the digital luggage for comfortable trips with everything under control.

How did having wifi in the car become so essential?

Today the whole journey goes through the mobile. Between real-time mapsonboard entertainment and work/study while travelling, having WiFi in the car stopped being a luxury. On long journeys —whether for leisure or work— you need connection to update routes, coordinate stops, hold video calls and keep kids entertained without draining personal data. Moreover, many car services and navigation apps run better with stable Internet, so having your own WiFi became the most comfortable (and safest) way to travel.

Leisure and family trips: entertainment, maps and no more “are we there yet?”

On leisure trips, wifi in the car avoids fights over mobile data and keeps everyone connected. Real-time traffic maps, music streaming and kids’ tablet videos become key in motorhomes, getaways or long routes. With your own wifi, you don’t rely on the driver’s phone coverage or battery.

Work trips: productivity on the move (always as passenger)

On business routes, having wifi in the car lets you send files, review documents, use VPN and join video calls as passenger. Teammates can also connect to the same access point and share Internet without splitting personal data. Result: meetings on time and fewer emergencies upon arrival.

Safer driving and connected vehicle

Many navigation apps and car services work better with constant Internet. Having your own wifi makes map updates, traffic or weather alerts and IoT devices (cameras, sensors, etc.) easier. It also avoids distractions from “lending the phone” for improvised tethering: the car’s network always stays ready for use.

How to get WiFi in the car? The best options

We reference the most common market alternatives and their real performance on trips. Below you’ll see each option with advantages and disadvantages to decide without doubts.

USB modem: basic but economical

A “dongle” or 4G/5G USB modem connected to a laptop (or compatible router) offers fast Internet with low initial cost. It requires mobile coverage and, in practice, the laptop usually acts as a “bridge” to share wifi.

Pros

  • Cheap and easy to find.
  • Simple setup: just plug and browse.
  • Useful if you already carry a laptop and only you connect.

Cons

  • Depends on the laptop to create a hotspot.
  • Coverage varies by country: you need a SIM/eSIM that works along the route.
  • Not the most comfortable for several devices at once.

eSIM with unlimited data plan and hotspot: the most versatile option

The most flexible choice today is using a data eSIM on your phone and sharing Internet via hotspot with passengers and car devices. No physical cards: you activate it with a QR code and you’re ready.

A MiFi device

MiFi are pocket routers with battery that share Internet via wifi with several devices. They work with SIM or eSIM (depending on model) and don’t rely on your phone.

Pros

  • Shares with multiple devices without draining phone battery.
  • Simple: a device dedicated to being a router.
  • Usually has a better antenna than some phones.

Cons

  • Another device to charge and monitor.
  • Extra cost (purchase/rental) + data plan.
  • If the route is international, you must check compatibility and coverage by country.

Installing Internet in the car

Some cars allow installing a fixed 4G/5G router (12V, OBD2 or manufacturer integrated). It’s a more professional setup for motorhomes, vans or company vehicles.

Pros

  • Stable signal and permanent wifi for everyone.
  • Better antenna/coverage and fixed power supply.
  • Ideal for motorhomes and intensive use.

Cons

  • Installation (sometimes technical) and higher initial cost.
  • Needs a dedicated data plan.
  • Less flexible if you change vehicle.

You can recycle an old smartphone as a car router. It works, but isn’t ideal in heat, long journeys or extreme climates.

Pros

  • Zero cost if you already own one.
  • Useful as emergency backup.

Cons

  • Battery and heat: performance and safety risk.
  • Poorer antenna than a MiFi/dedicated router.
  • Clumsy management if something fails on the road.

If it’s your first trip with onboard wifi and you want concrete consumption numbers per app (Zoom, YouTube, Netflix, etc.), remember to check our guide “How much data does your mobile hotspot use?”. If you want the simplest and most reliable choice, what works best in almost any scenario is an eSIM with unlimited data and hotspot. With Holafly Plans you activate by QR, switch your phone into hotspot mode and that’s it: the car gains stable WiFi for maps, music and work without relying on plugs or one-off top-ups.

That said, if you’re travelling with family or in a motorhome, a MiFi or 4G/5G router with a good data plan helps share the connection across many screens for hours; still, carrying an unlimited eSIM as backup gives you an immediate “plan B” when the router runs out of coverage or battery. If you travel solo with a laptop, a USB modem may work for occasional tasks; but once there are video calls or cloud services, the unlimited eSIM again proves the most comfortable choice for speed, autonomy and ease of use. And if your route is international, it’s smarter to choose Holafly Plans, with global coverage in more than 160 countries and 24/7 English support, to cross borders keeping your car’s WiFi without changing settings. With this choice, your car always travels connected and you forget the headaches.
