Independent

🇬🇧
Built for UK travellers
Made with British travellers in mind - post-Brexit roaming changes, holiday destinations, trips people in the UK actually take.

Always improving
More destination guides, more comparison tools, and more honest write-ups are in the works. Bookmark it and check back.
Why Yesim?
There are a handful of decent eSIM providers out there - Airalo, Holafly, Nomad, and others. After testing a few, Yesim came out on top for the destinations most relevant to UK travellers, with competitive pricing and a clean app experience.
This site exists to be genuinely useful, not to push one provider regardless. If that changes, the recommendation will too. Check out the FAQ for more on how the plans work and what to expect.
A note on affiliate links
Links to Yesim on this site are affiliate links. If you buy a plan, esimguy.co.uk earns a small commission - at no extra cost to you. This is how the site is funded. It doesn't change the plans shown, the prices displayed, or any recommendations made. We're required to tell you this under UK ASA/CAP guidelines, and we think it's only fair to be upfront about it anyway.
