Remaining connected has become almost a fundamental part of modern life. And car manufacturers are striving to make their new models increasingly focused on connectivity.

Just take BMW's 8th version of its iDrive system, or Mercedes' fancy new MBUX Hyperscreen fitted to the new electric EQS saloon. Even Ford is getting in on the game with its Tesla-esque Sync 4 infotainment system that makes its debut on the Mustang Mach-E.

And in regards to apps, almost every car brand has one these days. Yet, most cars don't actually offer Wi-Fi at the moment, as you get in your house. However, that can be changed with the purchase of a mobile Wi-Fi router, also called MiFi. Keep reading to understand if a MiFi device would be right for you.

Why get Wi-Fi for your car?

We should address the elephant in the room first. Yes, most people have big mobile data plans on their phones, and we will say that buying a mobile Wi-Fi router to use in the car is not necessary for everyone. But it is advantageous to some.

The Wi-Fi signal will remain strong, fast, and secure throughout your trip – this is great for streaming videos and music. And multiple devices can connect at once.

Mobile Wi-Fi routers let you take Wi-Fi-only devices with you (such as some tablets) on car journeys without having to use a battery-draining hotspot from your phone. Conversely, if you have a mobile Wi-Fi router, you can save money on your next tablet because Wi-Fi-only tablets are cheaper than the version with a 4G/5G data connection.

Using a mobile Wi-Fi router with a SIM on a data-only plan can actually make your portable internet connection fairly inexpensive.

CAR's top mobile Wi-Fi routers:

At constant use, the 2000mAh battery will give you about eight hours using 4G or, if left on standby, several days. To recharge, simply do so via USB. You can enjoy HD movies using this MiFi device thanks to a maximum of 150Mbps download speed.

As with everything these days, there is an app (tpMiFi) from which you can access all the information you need regarding how much data you’ve used, who’s connected, and all that sort of thing.

What about 5G?

Yes, there are 5G MiFi devices available. However, take note of the fact 5G is still quite new and devices such as Netgear Nighthawk M5 or the Huawei equivalent are very expensive.


When buying a SIM to put into an unlocked MiFi, it’s best to go with a provider that has good coverage. You can check via providers’ website – for example, Vodafone’s network status checker. Shop around, see who will offer you the best deal. It tends to save you money over time.

You can buy a mobile router such as the above 4GEE Mini Mobile Wi-Fi router, which already comes with a bundle from a network provider. Just remember that these lock you into that network provider’s coverage.
