In the UK, eSIMs are available from EE, giffgaff, Lyca Mobile, O2, Sky, Tesco, Three & Vodafone. You can use an eSIM in your iPhone, Samsung Galaxy or Google Pixel phone.

eSIM or embedded SIM technology is now available on the latest smartphones from Apple, Samsung and Google. On devices such as the iPhone 11, the Galaxy S20, the Pixel 3, and newer devices, you can download an eSIM on to your phone. This will allow you to get connected without the need for a physical SIM card. You can also use an eSIM to activate dual-SIM functionality on these phones.

You can get an eSIM on compatible Pay Monthly plans from EE, O2, Sky, Tesco, Three and Vodafone. You can also get a Pay As You Go eSIM from giffgaff and Lyca Mobile.

In this article, we’ll look at eSIM technology in the UK. We’ll start by asking what eSIMs are and how they compare to the traditional SIM cards that have been in use for more than 30 years. We’ll then look at the devices you can use an eSIM with, and at the support for eSIM across different UK networks.

What is eSIM?

In mobile phones, eSIM or “embedded SIM” is a new version of SIM card technology where the SIM card is embedded inside your device.

Instead of having a physical SIM card from your mobile network that you slot inside your device, eSIM uses a reprogrammable chip that’s already inside your mobile phone. To download and install an eSIM, you’ll normally need to scan a QR code with your mobile phone.

Compared to traditional SIM cards, there are both advantages and disadvantages to using an eSIM.

The advantage of eSIM technology is that it can make it a lot easier and faster to change to another mobile network. Rather than waiting for a SIM card to be sent to you through the post, you’ll simply need to download or scan an eSIM with your phone. In addition, many devices support dual-SIM connectivity when an eSIM is used. When you use both an eSIM and a physical SIM card, you’ll be able to have two phone numbers and two plans on your phone at the same time (e.g. one for personal usage and another one for work usage).

The downside of eSIM is that only a couple of mobile networks currently offer eSIM-compatible plans in the UK. There can also be complications when you change to another phone. With eSIM, it isn’t as simple as taking out a physical SIM card and putting it inside another phone. In addition, if you change to another phone in the future that lacks support for eSIM, you’ll need to change your eSIM back into a physical SIM card before you’re able to use it.

1 The Pixel 3 and Pixel 3 XL are able to hold both a physical SIM card and eSIM. You can change between the two but only one can be used at a given time. You therefore won’t be able to have two phone numbers at the same time.
2 The Motorola Razr is an eSIM-only device. It doesn’t support physical SIM cards.

For more information, see our full list of eSIM compatible phones.

Most of the above smartphones offer dual-SIM connectivity in conjunction with eSIM support. This means you can use a traditional plastic SIM card, an eSIM, or both at the same time. If you’re using both a traditional SIM card and an eSIM at the same time, you can have two phone numbers and two mobile networks on your phone at the same time.

For more information on how to set up and use eSIM on your phone, refer to your smartphone manufacturer’s website as follows:

eSIM on UK Mobile Networks

In the following section, we’ll discuss the availability of eSIM on UK mobile networks.


It’s currently possible to get an eSIM on EE’s Pay Monthly plans (including SIM Only and Small Business plans). Unfortunately, eSIM isn’t available to EE Pay As You Go customers.

To get an eSIM on EE, you’ll need to start off by getting a regular plastic SIM card. Once you’ve ordered and activated this SIM card, you’ll be able to get a new eSIM to replace it.

To get your replacement eSIM pack, you can log in to My EE, you can visit your nearest EE retail store, or you can call EE’s customer services team on 150 (0800 956 6000 if you’re calling from another network). Once you have your eSIM pack, you can use EE’s SIM swap webpage to transfer your plan onto an eSIM.

If you’d like an EE Pay Monthly SIM card that can be changed into an eSIM, consider one of the following EE SIM-only deals:

24 months
24 months
24 months
12 months
24 months

All of EE’s eSIMs come with access to their 5G network. In addition, you’ll get a Smart Benefit included when you choose an All Rounder plan. For instance, this could be an inclusive subscription to Apple Music, Netflix, or TNT Sports Ultimate.

Once you’ve placed your order, the SIM card will normally arrive on the next working day (as long as you order before 5pm).

You’ll then be able to use the ‘Switch to eSIM’ feature inside the giffgaff app which will download and install the replacement eSIM on your device.

If you’re a Tesco Mobile Pay Monthly customer, you’ll be able to move your plan onto an eSIM. To do so, you’ll need to request a replacement eSIM. This is available through live chat, phone (0345 301 4455), or in-person at your local Tesco Mobile phone shop.

Your Tesco Mobile eSIM will be issued as a printed QR code, which you’ll need to scan with the camera on your phone. According to Tesco, it can take a couple of days for the printed eSIM to arrive in the post as it will be sent to you via Royal Mail.

Other Networks

You can also get an eSIM plan from specialist roaming providers. For instance, Airalo offers a short-term UK plan with 3GB data for US$10 (approx £7.90). This is a data-only plan from Uki Mobile with 4G coverage from the O2 and Three networks. Unlike on the plans above, there’s no need to be a UK resident. However, you’re getting a data-only service without a UK phone number. This means it isn’t particularly suited for long-term usage in the UK.

Amongst the other UK network providers:

  • iD Mobile eSIM – Unfortunately, iD Mobile do not currently provide eSIMs on their network. They haven’t made any announcements as to when eSIM will be made available.
  • Lebara Mobile eSIM – At present, Lebara Mobile doesn’t offer any eSIM support on their UK network.
  • SMARTY eSIM – Smarty doesn’t currently support eSIMs on their network.
  • VOXI eSIM – Unfortunately, eSIM technology is not currently available to customers on VOXI (a youth-orientated sub-brand of Vodafone). As an alternative, you could consider getting a plan from Vodafone instead, given they have eSIM-ready plans from £7/month.

How To Set Up An eSIM

When you order an eSIM from one of the UK mobile networks, they’ll normally provide you with a QR code that you can scan with your phone. This is the easiest and fastest way to install an eSIM onto your device.

If, for some reason, you need to set up the eSIM manually (e.g. due to a broken camera or missing QR code), you can manually input the SM-DP+ address for your provider. You’ll also need the activation code and confirmation code, both of which are unique to your eSIM.

The following table shows the SM-DP+ address for the UK mobile networks:

eSIM Provider SM-DP+ Address Activation & Confirmation Code
EE (unique to your eSIM from EE)
Lycamobile (unique to your eSIM from Lycamobile)
O2 (unique to your eSIM from O2)
Three (unique to your eSIM from Three)
Vodafone (unique to your eSIM from Vodafone)

If you’re getting a giffgaff eSIM, this is only available as a direct digital download through the giffgaff app.

  • Hi Ken,
    thank you so much for this very structured and helpful article!! I need a second plan for just phone calls when I am in the UK (currently going back and forth between EU and UK). Lyca seems the best option for an e-SIM. What I don’t understand: Why does it say “30 day SIM card” and what does this mean in practice? I assume I install the e-SIM and they charge every month? Or do I have to renew every month? Will I be able to have a reliable permanent UK phone number?
    Thank you for your reply!! 🙂

    • Hi Wiebke,
      Thanks for your comment. If you buy one of the bundles from Lyca Mobile, the allowances included with it will be valid for 30 days (i.e. you’ll get unlimited UK minutes, unlimited UK texts & your allowance of data for the next 30 days). If you choose to turn off the auto-renewal of your bundle, you’ll switch to Lyca Mobile’s Pay As You Go rates (23p/minute, 23p/text and 15p/MB). There are no regular monthly fees here – you’ll just need to make a chargeable activity once every 120 days.
      Hope this helps,

  • Lyca mobile#’s website does not state if their e-sim is compartible with the Flip 5 so not sure if they’ve just not added the model or it just won’t work. Does anyone know if Lyca e-aim will work on Samsung Flip 5 please?

    • Hi Satura,
      Thanks for your comment. Thankfully, eSIMs are a standardised technology so you should be absolutely fine to use it on a Galaxy Z Flip 5. The most important thing is just making sure you have an eSIM-compatible device. Many websites provide a list of eSIM-ready phones to be helpful, but are not always kept fully up-to-date!
      Hope this helps,
