The post-Brexit roaming landscape
UK networks are no longer obliged to offer EU roaming at domestic rates. O2 is the sole major exception — it never brought charges back.
O2 — free across 49+ EU destinations
Included on every standard plan, with a fair-use data cap, no separate add-on required.
Three — the widest worldwide reach
Go Roam scales up to 163 destinations on the top tier, including India, Japan, the UAE, Canada, and Kenya.
Sky Mobile — a gap versus its own host network
Charges daily via an add-on rather than including EU roaming free, despite running on the same O2 network that includes it by default.
iD Mobile — wider than most MVNOs
Up to 50 worldwide destinations on top-tier plans.
Tesco Mobile — Home From Home
48 destinations free, using your normal UK allowance, with a 62-day continuous-use fair limit.

We do not sell SIM cards, contracts, or airtime, and we do not display or quote pricing anywhere on this site. If you contact us by phone or form, you are reaching Onuhiowise's own independent guidance team — never a network's official customer service line. Our team will always introduce themselves as Onuhiowise, an independent service, and will never claim or imply that we are O2, Three, EE, Tesco Mobile, Vodafone, Sky Mobile, iD Mobile, or any other network.
