The post-Brexit picture
UK networks no longer have to throw in EU roaming at no extra cost. O2 is the one holdout that never brought charges back.
O2 — free across 49-plus EU destinations
Bundled into every standard plan, with a fair-use data ceiling, no add-on required.
Three — the longest reach of the seven
Go Roam climbs to 163 destinations on the top tier, taking in India, Japan, the UAE, Canada, and Kenya.
Sky Mobile — the odd one out on its own network
Charges by the day through an add-on, even though O2 — the network it actually runs on — includes EU roaming free by default.
iD Mobile — wider than you'd expect for an MVNO
Up to 50 destinations on its better plans.
Tesco Mobile — Home From Home
48 destinations included free on your usual UK allowance, capped at 62 continuous days away within any four-month stretch.
A quick note on who we are: neylscout (neylscout.online) is run by independent researchers, not by any mobile network. We write about Three, O2, EE, Tesco Mobile, Vodafone, Sky Mobile, and iD Mobile because people ask us about them — none of these companies sponsor us, pay us, or have any say in what we publish. We are not a reseller and we never sell airtime, SIMs, or contracts through this site, and you won't find a single price on these pages, because prices move too often for us to keep accurate. If you ring the number on this site or fill in our form, you'll reach our own small team — never a network's official support desk, and never anyone able to touch your account. Every brand name and logo colour you see here belongs to the company it names; we use them only so you can tell which network a page is about, not to suggest any partnership. Treat everything here as a starting point for your own research, and check the final word with the network directly before you commit to anything.
