Best Pay As You Go eSIM

In the UK, it’s now possible to get an eSIM on Pay As You Go, with no need to sign a contract and with no need for a credit check.

Having an eSIM will allow you to access the dual-SIM functionality on newer iPhone, Samsung Galaxy and Google Pixel smartphones. For instance, you might be able to have two phone numbers at the same time on your device (e.g. both your work number and your personal number). An eSIM can also improve your mobile coverage by giving you access to another network, as well as giving you an extra allowance of mobile data.

At present, Lycamobile is our recommended network if you’re looking for a Pay As You Go eSIM plan in the UK:


  • Get your eSIM straight away. Just choose the “eSIM” option at checkout.
  • 6GB data & 1,000 UK minutes for £1/month: Or 20GB data & unlimited minutes for £10.

Uki Mobile

Uki Mobile is another provider of Pay As You Go eSIMs in the UK. Available exclusively through Airalo (which calls itself the world’s first global eSIM store), the Uki Mobile plans start from US$10/month (approx £8.40 per month).

Unlike the Lycamobile eSIM, Uki Mobile mainly pitches itself at tourists and visitors to the UK. Although there’s no reason why you wouldn’t be able to use it as a UK resident, there are two disadvantages to doing so:

  1. Uki Mobile offers a data-only eSIM. You won’t get a UK phone number included. As such, it isn’t possible to use the Uki Mobile eSIM for calling or texting.
  2. You’ll need to pay for your Uki Mobile eSIM in US dollars. As it’s a foreign currency transaction, there can be extra fees from your bank. The exchange rate and the resulting price in pounds sterling can also differ over time.

Apart from that, you’ll get access to O2’s 4G network on your Uki Mobile eSIM. There’s also no contract & no credit check when you sign up for a Uki Mobile plan.

The following table shows the latest Uki Mobile Pay As You Go plans:

Network Minutes Texts Data Cost
None None 1GB US$5
valid for 7 days
None None 3GB US$10
valid for 30 days
None None 5GB US$15
valid for 30 days
None None 10GB US$22.50

As a special offer for readers of this website, you can save 5% on your Uki Mobile eSIM when you enter the KEN5 voucher code at checkout.

Other Mobile Networks

Unfortunately, other UK Pay As You Go networks are still yet to offer eSIM on their Pay As You Go plans. This includes giffgaff who have said they’re still “looking into it”, and other mobile networks such as Lebara, SMARTY and VOXI who are yet to make an announcement.

If you’re looking for an eSIM plan from another provider, you can also consider Pay Monthly eSIMs from Vodafone, EE and O2. For more information, see our guide to eSIM on UK mobile networks and our comparison of the UK’s best eSIM plans. You’ll need to sign up for a Pay Monthly contract to get these other eSIM deals.

  • Surprised you haven’t mentioned KeepGo. $3 a year for a UK roaming, data only eSIM. It was someone else commenting on them in the comments on this very website that first piqued my interest!
