I’ll explain more about the eSIM for UK that I recommend below and why this option is the best UK sim card for visitors. Furthermore, esim in UK is the best sim card for London if this is your only stop in the United Kingdom.

Many travellers stop briefly in the UK to explore London in one day or on their way to visit some of the cheapest countries in Europe.

This article will define why the best eSIM for UK has the convenience, affordability and reliability you require when considering options for buying a sim card in the UK.

eSIM for UK travel is a great option, and the digital UK sim card plans start from just $5 for 1GB of data. And, it takes less than five minutes to download an e sim card for the UK.

What is an eSIM? How does eSIM work? 

An eSIM is a digital or virtual version of your physical SIM card. An eSIM allows you to trigger a cellular plan from a local carrier (UK esim providers in this case) without using a material SIM. 

I understand that this all can sound a little techy, but this new technology is a godsend for buying a sim card in the UK without the hassle. 

Your phone or device already has a microchip that allows you (or your newly purchased UK eSIM data package) to install multiple eSIM profiles. It’s equal to having multiple material SIM cards with phone numbers and data plans simultaneously packed into your phone. 

More about the best e SIM card for the UK

Buying a SIM card in the UK is so easy with the introduction of eSIM. The best UK sim card for visitors is the one that ticks all the essential boxes.

A few years ago, the best SIM card for the UK would have been difficult to answer, as so many big companies compete in this space. And, of course, they’re all still out there. 

We can thank technology for revolutionising how we stay connected in 2023 and beyond. The best SIM card for the UK is eSIM.

Now you can ditch the traditional SIM card and connect with eSIM in the UK. It’s the future, and I promise that it will only make your travelling life so much easier.

What is the best e SIM card for the UK? 

There are 6 x eSIM data packs to choose from. All data packs are well-suited for your trip to the United Kingdom. As I mentioned, this is the best sim card for London for a short stay, as the data packs are super affordable!

The trick to selecting from the range of e sim card plans for UK is down to you. You must choose the best eSIM for your individual needs. The best eSIM depends on how long you plan to spend in the United Kingdom.

Furthermore, consider how much data you will likely use to get the best value from your eSIM for UK.

If you’re in the UK very briefly, or even for a stopover – I’d recommend the 1GB for $5 data pack. Quick, cheap and easy, with enough data for checking the essentials online.

If you regularly use wifi during your travels (hotels and cafes usually offer these free of charge), you should go with the smaller plan ($10 for 3GB of data, valid for 30 days).

Yet, if you’re usually dependent on phone coverage for your data, you may require a plan that contains more data. I’d recommend either this $15 for 5GB eSIM or the 10GB eSIM for $22.50. Both data packs have 30 days of validity. 

The largest e sim for UK data plan is 20GB for $36, valid for 30 days.

Is eSIM easy to download to my device?

Absolutely! But before buying an eSIM for the UK, remember to double-check that your device is compatible.

You can check if it’s compatible here. Most phones and devices will support eSIM, but a small handful does not.

How to Download eSIM to your Phone or Device

Once you have checked that your device is compatible with eSIM for UK, you can go ahead. 

Download the Airalo App, purchase your selected data package and follow the steps to activate the eSIM for the UK just before your arrival.

Before arriving in the UK, switch from your home mobile provider to the UK eSIM provider.

Once your UK eSIM is activated, it’s best to turn off data for all apps that you don’t use daily, and those apps that use a lot of data:

Netflix, Instagram, and TikTok will eat through your data quickly. Try to leave social media scrolling when you get connected to Wi-Fi at your hotel or cafe. 

Your data will survive considerably longer. 

Easily top up your eSIM within minutes

A bonus about buying an e sim for UK is that you can easily top up your eSIM with more data whenever you’ve reached your limit.

In addition, Airalo automatically sends you an alert to let you know when your data has almost gone.

Why eSIM for UK is the best choice

If you travel to the UK, of course, you can purchase a local SIM card at any major airport or phone store/provider. 

This option allows you to make calls and send text messages within the UK. It also gives you access to local calling rates and data. 

However, I believe purchasing an eSIM card for the UK is a much better option than buying a local SIM in the UK:

You can download a UK eSIM before your departure from home instead of purchasing one in the UK. If you’ve got a prepaid eSIM activated upon arrival, you can get online as soon as you touch down in the UK! So avoid the crowds, exit the arrivals hall and go and explore right away!
