SIM cards for cars

As technology continues to make the world more connected, cars fresh off the production line are now equipped with something previously reserved for mobile phones: SIM card slots.

SIM cards have been bringing people closer together through handsets since the early '90s. But do we need them on the move? Can they really help us while driving?

In this article, we look at SIM cards for cars and suggest the best ways of improving connectivity behind the wheel.

What are the benefits of SIM cards for cars?

First, smart technology gave us better connections on our phones. Then it upgraded our homes, which now contain everything from internet-enabled TVs to virtual assistants like Google and Alexa.

Now it's only logical that our vehicles follow suit. Using SIM cards for cars allows us to enjoy many online conveniences, such as:

  • Live traffic updates to your sat-nav or GPS system
  • Music streaming to vehicle speakers from online apps like Spotify
  • Calls and texts coming through to the dashboard/speakers instead of your phone
  • An additional Wi-Fi hotspot for others in your car
  • Video streaming to backseat screens, perfect for in-car entertainment
  • Real-time directions
  • Full control over smart home systems like lights and heating while on the go


Which cars have SIM card slots?

An increasing number of car companies are starting to feature SIM card slots in their new vehicles.

Some of the most popular platforms that support SIM cards for cars include:

  • BMW Connected Drive
  • Audi Connect
  • Volkswagen Connect

Of course, this list will only get longer as more and more car companies begin utilising SIM card technology.


Do you need a SIM card for your car?

SIM cards for cars may be a relatively recent development, but their appeal is undeniable. Knowing which SIM you need for your car means first considering how you want to use it, and to what extent.

Data only SIMs are an excellent compromise, as they provide connectivity without the distraction of incoming calls or text messages.* However, if you want full mobile capabilities whenever you’re in the car, opting for a regular SIM is your best bet.

You may even decide not to get a new SIM at all, instead preferring to use your current smartphone for live updates/traffic directions. Just remember that your car’s connectivity will depend on its make and model, and there may be some functionality issues if you don’t have an in-car SIM already installed.

*Please note that using your phone while driving constitutes a breach of the law. Only hands-free use of your device is legal, and it must be secured in a cradle.


What to look for in SIM cards for cars?

When choosing a SIM card for your car, ask yourself the following two questions:


How much do they cost?

SIM plans vary in price across today’s market; be sure to shop around. Also, remember our top tip: don't think a data only SIM will necessarily be more affordable than a regular one. Otherwise, you could end up overpaying for a suitable card.

You can find plenty of generous SIM only deals to get excited about, providing your research is thorough.


Is there a decent data allowance?

SIM cards for cars do not usually require tons of data (unless excessive video or music streaming happens). In fact, you may only need as little as 1GB per month!

Ultimately, how much data you need will depend on usage while in the car. To be safe, opt for a middle-of-the-road data allowance, like 5GB for £7. Then, after a month, once you’ve monitored the amount of data you’re using, adjust your plan accordingly.
