Are you still struggling with the hassles that come with traditional SIM cards? Gone are the days of juggling tiny plastic SIMs when you need mobile data. In the UK, a new eSIM UK revolution is underway. In this guide, we’ll break down what an eSIM is, how it works, its top advantages, and why you should buy an eSIM plan in the UK!
What is an eSIM?
An eSIM is essentially the same as a normal SIM, but embedded in your phone. It still holds your mobile subscriber identity, phone number and network credentials, but instead of a removable chip, you manage it via software. When you change carriers on an eSIM, it’s done with a software update, not by swapping cards. In other words, your phone already has the eSIM hardware on board; there’s no need to “install” anything physically. In fact, all the major UK networks now support eSIM UK plans on compatible devices. So when you pick up a new smartphone today, it often already has an eSIM chip waiting to be set up.
How Does an eSIM Work?
eSIM is similar to a SIM card in terms of its purpose, but very different when it comes to features and setup:
- Digital activation: Like a SIM card chip is inserted in a device, an eSIM profile is downloaded. Once you buy an eSIM plan, you get a QR code from the provider. You scan that QR code on your device, and it starts working instantly.
- Rewritable profiles: eSIM gives you a lot of flexibility. You can change carriers anytime without swapping any cards. You can add any data plan or international profile as you want.
- Buy in Advance: If you are an international traveller, you can buy an eSIM in advance. Trusted providers offer you local eSIM of foreign countries online that you can buy in advance and stay connected as soon as you land.
What are the Advantages of eSIM?
Traveller or a local, eSIM UK offers you great advantages that are far better than a traditional SIM:
- Easy to Buy: You don’t have to visit any shop or wait for delivery to use an eSIM. You can simply buy an eSIM online and activate it as soon as you come under the network.
- Multiple Payment Methods: eSIM gives you the ease to pay as you want. You can even pay through Bitcoin with some providers.
- Safer Option: eSIM is a safer option than a SIM card. It cannot be stolen or damaged. You also get safety against swapping scams.
What is the Difference Between an eSIM and a Physical SIM?
Though the purpose of eSIM and a SIM card is the same, there are still many significant differences that you should know:
| Feature | eSIM (embedded SIM) | Physical SIM |
|---|---|---|
| Form factor | Built into the device (no slot needed). Easy to hide, hard to lose. | A removable plastic card that fits in a tray. |
| Activation | Set up digitally (scan QR code or use an app). | Insert the card manually; it often needs a PIN. |
| Switching | Change plans/networks in Settings with a tap. | Must swap cards or get a new SIM. |
| Security | Harder to steal (chip is locked inside). Reduces SIM-swap risk. | Can be removed/stolen; vulnerable if PIN is compromised. |
How to Set Up an Esim?
Ready to get started? Setting up an eSIM is usually a breeze if you know the right steps:
- Buy your plan: Go online and select any plan for the UK, Europe or a global data package. You can also buy EE eSIM, one of the best in the UK. (Providers like eSIM Cards let you select a destination and pay instantly.)
- Get the QR code: Right after purchase, you’ll receive an activation QR code (usually by email).
- Open cellular settings: On your phone, go to Settings > Mobile/Cellular > Add eSIM (or similar network settings on Android). Choose the option to add or download an eSIM profile.
- Scan and connect: Use your camera to scan the QR code. The phone will fetch the plan and activate it. In seconds, you should see the new data plan listed on your device; no more plastic SIM to insert.
How to Check eSIM Compatibility?
Before buying, make sure your phone supports eSIM. Most newer smartphones do, but here’s how to check:
- On iPhone: Go to Settings > General > About. Scroll down: if you see a section called Available SIM or Digital SIM, your iPhone has an eSIM chip. You may also see an EID number; that the embedded SIM hardware exists.
- On Android: The exact menu can vary. One trick is to open the dialler and type *#06# – if an EID number appears (alongside the IMEI), your device supports eSIM. Or check the network settings: go to Settings > Network & Internet (or Connections) > SIM cards. If you see an option like “Add eSIM” or “Add mobile plan,” you’re eSIM-ready.
- Other checks: Many flagships (new iPhone models, recent Samsung Galaxies, Google Pixels, etc.) come with eSIM. If in doubt, your carrier or a quick web search (with your phone model) can confirm compatibility.
How eSIM Makes International Travel Easier and Faster?
For travellers, eSIMs are a genuine game-changer. As you land in a new country, you will instantly have data, no airport SIM kiosk or pricey roaming bill in sight. You simply buy eSIM travel plan before you go and install it at home. When your plane lands, your phone connects to a local network automatically. It ends the usual travel hassles: no hunting for Wi-Fi, no eye-watering roaming fees, no waiting in SIM card queues.
How to Setup Your eSIM through the eSIM Cards App?
The eSIM Cards app (available on the App Store) makes setup very easy. Just download the app and browse for the plan you need; it could be a UK data plan or a multi-country pack. After purchase, open your iPhone’s Settings > Mobile Data (Cellular) > Add eSIM. The app provides a QR code or a direct install prompt. Point your camera at the code (or tap the install button), and your iPhone will configure the eSIM. It usually takes only moments for the new plan to activate. Thanks to eSIM, the process is mostly automated; you never have to remove any tray or call tech support.
