For years, getting connected meant waiting for a little plastic card to arrive in the post, then carefully prising open a tray with a paperclip and hoping you did not drop the SIM down the back of the sofa. An eSIM does away with all of that. It is a digital SIM built right into your phone, so instead of fitting a card you scan a code and activate your plan — often in a matter of minutes. If your phone supports it (most recent models do), an eSIM plan is the fastest, tidiest way to get online. Here is how it works, step by step.
Setting Up an eSIM in Five Steps
- Check your phone supports eSIM. Most phones released in the last few years do, but it is worth confirming in your settings before you order.
- Choose your plan. Pick the data allowance that suits you — the eSIM plans below all run on a rolling 30-day term with no contract.
- Receive your activation code. There is nothing to wait for in the post; the QR code arrives digitally.
- Scan and activate. Open your phone’s mobile-plan settings, scan the code, and follow the prompts. Once the code is scanned, you are online.
- Bring your number across, if you want to. Keep your existing number so nothing changes for your contacts, or run the eSIM as a second line alongside your current one.
eSIM vs Physical SIM at a Glance
The appeal of a digital SIM comes down to convenience, and the differences are easiest to see side by side.
| Factor | Physical SIM | eSIM |
|---|---|---|
| Getting started | Wait for delivery, then fit the card | Scan a code and activate in minutes |
| Losing or damaging it | Possible — it is a tiny card | Nothing to misplace; it lives inside the phone |
| Running two numbers | Needs a dual-SIM tray | Add a second line without touching your main SIM |
| Keeping your number | Yes | Yes |
| Switching phones | Move the card | Transfer the profile in settings |
The Plans Built to Run on eSIM
All of the plans available on eSIM include unlimited UK calls and texts and 100 international minutes on a rolling 30-day term.
eSIM Activation
The starting point — set up your plan digitally and get connected in minutes, with no physical SIM to insert and no waiting for the post. Best for anyone who wants to be up and running straight away.
UK Plan Unlimited
Unlimited data with unlimited UK calls and texts, 100 international minutes and EU and India roaming — all on an eSIM. It pairs the most flexible SIM format with the most generous allowance, so there is nothing to ration or wait for. Best for heavy users making the leap to eSIM.
UK Plan Super Extra
75GB of data with unlimited UK calls and texts, 100 international minutes and EU, China and India data roaming. A strong middle option with plenty of data and wide roaming on a digital SIM — a great fit if you travel and want a second line ready to go. Best for regular users who want flexibility and reach.
Keep Your Number
Moving to an eSIM does not mean starting over — bring your existing number across when you switch, so nothing changes for the people who call and text you. Best for anyone upgrading to eSIM without losing their number.
Three Situations Where eSIM Really Shines
Setting up a brand-new phone. You can be connected the moment the phone is out of the box, with no trip to a shop and no waiting for a card.
Adding a second line. Keep your work and personal numbers on one handset, or add a dedicated line for a trip, without touching the SIM you already use. Many phones let you choose which line handles calls and which handles data.
Switching without downtime. Because there is nothing to deliver, you can pick a plan, activate it and bring your number across in a single sitting. Have your details ready and the whole thing takes minutes rather than days.
Final Thoughts
An eSIM strips the hassle out of getting connected — no plastic, no waiting, and your number comes with you. If your phone supports it, going digital is the easiest switch you will make, and dual-SIM support is a bonus for keeping work and personal lines separate or adding one for travel.
