Find the right eSIM plan
Choose the eSIM that fits how and where you want to connect.
UK eSIM plans
Stay connected in the UK with a full-service eSIM plan. Our UK eSIM options are ideal if you want mobile data, calls and SMS without using a physical SIM card. They are suitable for compatible iPhone, Android and other eSIM-enabled devices.
Travel eSIM plans
Travelling abroad? A travel eSIM lets you arrange mobile data before you leave, so you can get online when you arrive. Use maps, messaging apps, email, transport apps and browsing without relying on airport SIM shops or expensive roaming.
Data-only eSIMs
A data-only eSIM is perfect if you mainly need internet access while travelling. Use your eSIM for WhatsApp, FaceTime, Google Maps, email, social media and web browsing while keeping your main SIM active where your device supports dual SIM.
Full-service eSIMs
Some customers need more than data. Our full-service eSIM plans can include voice, SMS and mobile data, giving you a more complete mobile service directly on your eSIM-compatible device.
How does an eSIM work?
Getting started with an eSIM is simple.
| Step | What you do |
|---|
| 1. Choose your plan | Select the eSIM plan that matches your destination, data needs and length of use. |
| 2. Buy online | Complete your purchase securely through eSIM.net. |
| 3. Receive your QR code | Your eSIM activation details are sent digitally, so there is no physical SIM card to wait for. |
| 4. Install and connect | Scan the QR code on your compatible device, follow the setup steps, and start using your eSIM. |
Why choose an eSIM instead of a physical SIM?
An eSIM is a faster, cleaner and more flexible alternative to a traditional plastic SIM card.
No waiting for delivery
With a physical SIM, you may need to wait days for the SIM card to arrive. With an eSIM, your activation details are delivered digitally, so you can get started much sooner.
No SIM card swapping
There is no need to open your SIM tray, handle a tiny plastic card or switch SIMs when you travel. Your eSIM is installed directly onto your compatible device.
Keep more than one plan on your phone
Many modern phones allow you to store multiple eSIM profiles. This makes it easier to keep one plan for everyday use and another for travel, work or international data.
Better for travel
An eSIM is ideal for travel because you can buy your plan before you leave, install it before you fly, and connect when you arrive. It is a practical alternative to buying a local SIM card at the airport or paying high roaming charges.
Keep your main number active
On many dual-SIM phones, you can use an eSIM for mobile data while keeping your regular SIM active for calls, texts and messaging apps.
Less plastic and packaging
Because an eSIM is digital, it avoids the plastic SIM card, packaging and delivery process associated with traditional SIM cards.
eSIM vs physical SIM
| Feature | eSIM | Physical SIM |
|---|
| Delivery | Digital delivery | Requires postage or collection |
| Activation | Scan a QR code or follow digital setup steps | Insert SIM card manually |
| Travel use | Easy to install before travelling | Often bought on arrival or posted in advance |
| Multiple plans | Store multiple eSIMs on many compatible devices | Usually limited by physical SIM slots |
| Convenience | No SIM tray, no plastic card, no delivery delay | Requires handling and swapping SIM cards |
eSIM vs roaming
Using your usual mobile provider abroad can be expensive, especially if your plan does not include generous roaming. A travel eSIM gives you more control because you choose a plan in advance and know what you are buying before you travel.
With a travel eSIM, you can:
- Avoid unexpected roaming charges.
- Choose a plan for your destination.
- Use mobile data for maps, taxis, hotels, messaging and email.
- Install your plan before departure.
- Connect quickly when you arrive.
- Keep your main SIM available on compatible dual-SIM phones.
