Driving Through Europe With An eSIM: A Complete Guide
Quick answer: Using an eSIM on a European road trip gives you instant internet access without high roaming charges. You can keep your regular phone number active for texts and calls while using the digital SIM for affordable local data. Many providers offer excellent coverage across Europe.
Planning a driving holiday across the continent is incredibly exciting. You get to map out your routes, pack your bags and set off on the open road. But one thing that always causes a bit of stress is figuring out how to stay connected to the internet. We all need mobile data for maps, finding places to eat and keeping in touch with loved ones back home. That is why I recommend you use an eSIM.
In the past, you had to hunt down a local phone shop in a foreign country and swap out tiny plastic chips. You then had to worry about losing your original chip in the bottom of your bag. Thankfully, digital technology has changed how we travel. You can now download a digital data plan straight to your phone before you even leave your house.
If you are currently packing your bags and checking your European road trip essentials, sorting out your mobile data should be right at the top of your list. Setting up digital data plans might sound slightly complicated at first. However, the process is actually very simple once you know the basics.
This guide will explain exactly how to manage your mobile connection while driving abroad. We will look at how much data you really need, how to fix common connection problems and why having instant internet access can make family holidays much less stressful.
What is the best way to use an eSIM in Spain?
Using an eSIM in Spain is incredibly straightforward. A digital SIM is simply a reprogrammable chip that is already built into your smartphone. Instead of inserting a new piece of plastic, you just buy a data plan online and scan a QR code to install it.
When you cross the border into Spain, your phone will automatically connect to a local Spanish network like Movistar, Orange or Vodafone. This means you have instant access to Google Maps for navigating those tricky Spanish motorways.
To get the best experience, you should buy and download your data profile while you are still at home connected to your own Wi-Fi. You can then leave the line turned off in your phone settings. As soon as your plane lands or you drive across the Spanish border, simply go into your phone settings, turn the new line on and make sure data roaming is enabled for that specific profile.
If you plan to drive through multiple countries, you do not need to buy a new plan for every single border crossing. Many companies sell regional European plans that cover over thirty countries. This allows you to drive from France into Spain and then over to Portugal without ever losing your internet connection.

What are the best eSIM providers for a holiday in Spain?
Choosing the right company for your trip depends entirely on how long you are staying and how much of the internet you plan to use. There are dozens of companies out there, but a few stand out for their reliability and price.
Airalo is one of the most popular choices for tourists. According to Airalo in 2024, they offer digital data packages for over 200 countries and regions. Their Spanish packages are very affordable and use reliable local networks. You can easily track how much of your allowance you have used through their mobile app.
Saily is another fantastic option created by the team behind NordVPN. They focus heavily on security and fast connections. Saily often provides great value if you are looking for larger allowances for longer trips.
Holafly is a brilliant choice if you do not want to worry about running out of megabytes. They offer unlimited data packages for Spain and the wider European area. You will pay a bit more upfront, but it brings great peace of mind if you love streaming videos or need to upload hundreds of holiday photos every evening.
Can you use an eSIM and your normal number at the same time?
Yes, you absolutely can use both at the same time. This is one of the biggest benefits of modern smartphones. According to Airalo, most modern devices feature Dual SIM technology. This allows your phone to hold multiple network profiles at once.
You can keep your normal UK physical chip active so that your friends and family can still call or text your regular phone number. At the same time, you tell your phone to use your new digital profile solely for accessing the internet. So in essence, your phone knows to use an eSIM for internet and your normal phone for calls and texts.
To set this up on an iPhone, you need to go into your mobile data settings. You will see an option to label your lines. You could name your normal line “Personal” and your new digital line “Travel”. You then set your “Default Voice Line” to your personal number. Next, you set your “Cellular Data” line to your new travel profile.
Android phones have a very similar process under the network and internet settings menu. Just ensure you turn off data roaming on your home UK network. If you leave data roaming turned on for your home network, your UK provider might charge you expensive daily roaming fees.
How much data do you actually need on a European holiday?
Working out your data needs can feel a bit like guessing the lottery numbers. However, you can make a very good estimate by looking at your normal daily habits. Travel packages usually range from 1GB all the way up to 50GB, you need to use an eSIM with allowances to cover what you need to avoid extra charges.
If you just want to check Google Maps, send a few WhatsApp messages and occasionally search for a local restaurant, 1GB of data per week is usually plenty. Text-based messages and basic map navigation use very little data.
If you like to scroll through social media platforms like Facebook or Instagram while lounging by the pool, you will need quite a bit more. Videos and high-quality images consume megabytes very quickly. In this case, 3GB to 5GB per week is a much safer bet.
If you are travelling with children who want to stream Netflix in the back of the car, or if you need to do remote work and host video calls, you will need a large package. You should look at plans offering 10GB to 20GB, or even consider an unlimited package from a provider like Holafly. Always remember that you can usually connect to free Wi-Fi at your hotel or in local cafes to save your mobile allowance for when you are actually on the road.
Why did an eSIM make travelling with a disabled family member easier?
Travelling with a disabled family member requires a lot of careful planning. You need to know exactly where you are going, where the accessible parking spots are and where you can find suitable facilities. Losing internet access in a foreign country can turn a minor inconvenience into a majorly stressful situation.
Having an active digital data plan completely changes this dynamic. When we drove through Europe, we never had to worry about getting lost because our navigation apps were always online. If we needed to locate the nearest pharmacy, the information was always right at our fingertips.
There was no hunting busy city centres trying to buy a plastic chip while juggling luggage. We arrived in the country with our internet already working. This instant connectivity provided a massive safety net. We could use translation apps instantly if we needed to explain specific medical needs and allergies to a local pharmacist. It just removed a huge layer of anxiety from the trip, allowing us all to actually relax and enjoy the holiday together. If you have someone with allergies, disabilities etc then I highly recommend you use an eSIM on your holidays.
Help! What should I do if my eSIM is not working abroad?
Technology is wonderful when it works, but it can be very frustrating when it fails. If you arrive in Europe and plan to use an eSIM but find that you have no internet connection, do not panic. Most problems are very easy to fix. According to the troubleshooting experts at SimOptions, there are a few simple steps you should try.
First, turn on Airplane Mode for 30 seconds, then turn it back off. This simple action forces your phone to completely disconnect from all networks and search for a fresh, clean signal. It works surprisingly often.
Second, check that your digital line is actually turned on. Go into your mobile settings and make sure the travel profile is active and that data roaming is enabled specifically for that line.
Third, try manually selecting a network. Sometimes, when you use an eSIM, your phone tries automatically to connect to a network that has a weak signal. Go into your network selection settings, turn off the automatic search, and manually choose a different local provider from the list that appears.
Finally, if you are still trying to use an eSIM and having no luck, check your balance with your provider. It is surprisingly easy to accidentally leave an app running in the background and use up all your megabytes, even when you use an eSIM. If none of these steps works, restart your phone completely. A full reboot often clears out any hidden software glitches.
Ready for your next adventure?
Sorting out your internet connection should never be the most stressful part of your holiday. By downloading a digital profile to use an eSIM before you leave, you can focus entirely on creating wonderful memories on your European road trip. You will have instant access to maps, translation tools and local guides the moment you cross the border.

Frequently Asked Questions about European eSIMs and how to use an eSIM
Do I need to remove my physical SIM card to use a digital one?
No, you do not need to remove your physical SIM card to use an eSIM. Modern smartphones allow you to run your normal physical line and a new digital line at the same time. This means you can still receive phone calls on your regular number.
How do I know if my smartphone supports digital SIM technology?
Most premium smartphones manufactured after 2018 support this technology. This includes the iPhone XS and newer models, as well as the Samsung Galaxy S20 and newer. You can usually check by looking in your mobile network settings to see if there is an option to “Add eSIM” or “Add Cellular Plan”.
Can I use my data plan as a personal hotspot for my family?
Yes, most travel providers allow you to use your mobile phone as a personal hotspot. This is so useful if you want to share your internet connection with your children’s tablets in the back of the car. Always check the terms and conditions of your specific package, as some unlimited plans occasionally restrict hotspot sharing. If you want to use an eSIM for this then check before buying!
Will I lose my WhatsApp conversations if I use a different data provider?
No, your WhatsApp account is tied to your phone number, not the network you are using for the internet. When you connect to the internet using your new digital profile, WhatsApp will continue to work exactly as normal. You will not lose any of your chats or contacts if you use an eSIM.
Can I buy a digital data plan for just one specific country?
Yes, you can buy plans that only work in one single country, such as Spain or France. These single-country packages are often slightly cheaper. However, if you are doing a road trip across multiple borders, buying a regional European package is usually much more convenient.
Have you ever considered a road trip, like we do, abroad? You could use an eSIM, too, to save time and money!
