What to install before you land in United Kingdom

The eSIM gets you online — these are the local apps it unlocks the moment you arrive.

  • National Rail + Trainline

    National Rail gives live departures + platform changes; Trainline is best for split-ticket savings on cross-country journeys. Both accept Railcard discounts in-app.

  • Citymapper

    Made for London; handles every quirk of Tube + bus + cycle hire + Thames Clipper. Now decent across Manchester, Birmingham and Edinburgh too.

  • Bolt / Uber

    Both run in every UK city; Bolt undercuts Uber on weekdays. FreeNow handles licensed black cabs in London — useful for late-night rides home.

  • TfL Go

    Official Transport for London app with step-free access info + real-time service alerts. Pay-as-you-go contactless still wins over paper tickets — set your home card before you fly.

Local prepaid SIM vs. our free eSIM in United Kingdom

What you’d pay at the airport SIM kiosk — and what you save by activating the eSIM before you fly.

Local prepaid SIM
EE PAYG Starter
£20· 20 GB / 30 days
No ID required — No ID — but the Heathrow T5 EE counter queue is regularly 20+ min on weekend mornings.

Bigger headline allowance, but you trade ~30 min of arrival time queuing. Most weekend visitors barely need 5 GB.

Free eSIM for United Kingdom FAQs by co:sim

Everything you need to know about the free new-user eSIM offer.

Does the free eSIM work on the London Underground?
Yes on the lines fitted with TfL’s in-tunnel antennas: Elizabeth, Jubilee, Central, Victoria and most of the Northern line. Bakerloo and the western Piccadilly still lose signal between stations. Overground + DLR are fully covered.
Will it work in the Scottish Highlands?
Scotland uses the same UK profile and EE reaches every major town + the central belt + most A-roads. Single-track Highland routes still have dead zones; don’t rely on it alone for remote hiking.
Does it work across the border in Ireland?
Yes. Cross from Belfast and the eSIM hands over to Vodafone Ireland or Three Ireland — both included in the 33-country plan. No roaming charge and no profile swap.
What about Channel Islands and Isle of Man?
No — Jersey, Guernsey and the Isle of Man are Crown Dependencies outside the eSIM’s zone. Switch data roaming off before the ferry; charges can be steep.
How does it compare to keeping my home roaming on?
US carriers charge $10–$12/day for UK roaming. Our 7-day free plan + a £2.99 top-up if you blow past 1 GB is still cheaper than a single day of US roaming.
Who's eligible for the free eSIM?
New users who have not previously claimed a free eSIM. Eligibility is verified at checkout.
Will I be charged anything?
$0 is charged for the free eSIM. A valid card is collected at checkout for verification only — this prevents the same person claiming multiple free eSIMs. You only pay if you choose to top up later.
How long is the free eSIM valid?
Install and activate the eSIM within 30 days after purchase. Once activated, the free plan is valid for 7 days from your first connection. After that, top up anytime to extend the validity — the same eSIM keeps working.
Can I top up or buy more data after?
Yes. Top up the same eSIM with any paid plan at any time — your data and validity extend instantly, no reinstall required. You can also buy plans for any of our 190+ other destinations.
Can I claim the free eSIM again?
No. This free eSIM is a new-user offer, so it can only be claimed once.
How does the free plan compare to paid plans?
Same high-quality network coverage. Paid plans offer more data and longer validity — and you can top up onto your free eSIM at any time.
