While eSIMs have been around for a long time, these embedded SIM cards still aren’t supported by all UK networks, and even fewer offer them on Pay As You Go.
That said, you do have some options if you want to get an eSIM on a Pay As You Go plan. We’ll cover them below, and if you’re not sure what an eSIM is – or why you might want one – check out our guide covering what is an eSIM and which networks/phones support eSIMs.
Note also that you need a phone that supports eSIMs in order to use one, but these are widely available, and the guide above details many of your options.
Which networks offer eSIMs on Pay As You Go?
At the time of writing, six networks officially offer eSIM on Pay As You Go. These include Three, Vodafone, Giffgaff, iD Mobile, Lyca Mobile, and Tesco Mobile.

We’ll talk those through in more detail under dedicated headings below, but note that while the following information is accurate to the best of our knowledge at the time of writing, if in doubt you should check directly with the network you're interested in using an eSIM with.
Three
Three is one of only two of the four main UK networks to offer eSIMs on Pay As You Go at the time of writing, though the others do offer eSIMs on Pay Monthly plans.
In any case, you can’t request an eSIM while signing up for a Pay As You Go plan on Three, but once you’ve received a physical SIM card, you can call Three’s contact centre or visit a Three store to request an eSIM in its place.
You may soon be able to request an eSIM at checkout though, as there is a toggle for this, just oddly at the time of writing it’s greyed out.

Vodafone
Along with Three, Vodafone is the other major UK network that supports eSIMs on Pay As You Go plans.
It’s simple to get an eSIM on Vodafone too, because you can request one during checkout, then simply follow the instructions that Vodafone will email to you to activate it.
If you already have a physical SIM card on Vodafone, then just contact the network to switch to eSIM.

If you already have a physical SIM then you can switch by opening the Giffgaff app and heading to Account > SIM > Replace my SIM > Switch to a new eSIM, then simply follow the steps to install your new eSIM.

Lyca Mobile
Lyca Mobile also lets you use an eSIM with its Pay As You Go plans, and better yet you can request one when placing your order. Just tap the eSIM option during checkout.
You’ll then receive an email containing an eSIM QR code. Just point your phone’s camera at this, and follow the prompts to install it.
If you already have a physical SIM card with Lyca Mobile, then you can switch to an eSIM by heading to your Lyca Mobile online account, then SIM Management > SIM Swap > Swap Physical SIM to eSIM.
Tesco Mobile
Tesco Mobile’s site doesn’t make it clear whether eSIMs work with Pay As You Go or just Pay Monthly, but a customer service agent assured us that you can access them on Pay As You Go.
Getting one at checkout doesn’t appear to be an option online, but you can give Tesco Mobile a call or head in store to get one, or to switch to one if you already have a physical SIM card.
