Who we are. Keyanok is an independent information and guidance service for United Kingdom mobile customers. We are not a mobile network. We have no affiliation with, endorsement from, appointment by or connection to Three, EE, O2, Vodafone, Sky Mobile, Tesco Mobile or any other provider, and no commercial arrangement with any of them. We do not sell, supply, arrange or broker SIM cards, contracts, handsets or services of any kind, and we take no commission. Everything on this site is general information; a provider’s own current terms always take precedence.

Where each network stands

Sky Mobile

What it means for you

NetworkPosition in Europe
O2Still included on standard plans, under a published ceiling — the only one of the four
ThreeDaily charge on most current plans; some older plans kept it included
EEDaily charge on most current plans; some higher tiers restore it via a pass
VodafoneVaries by plan generation — check your own screen
Sky MobileDaily passes chosen by band
Budget brandsThe brand’s own terms apply, never the landlord’s

Two people on the same network can be on entirely different rules depending on when they signed. Nothing on a marketing page settles this — only the roaming screen in your own app.

What a fair-use ceiling actually does

The facts

Applies
Everywhere abroad, on every network
Nature
A published data limit
Past it
Per-gigabyte charging begins
Where bills come from
This, not the daily fee

What it means for you

“Included” roaming is included up to a published limit. Beyond that limit, per-gigabyte charging starts.

That is where the alarming bills come from — not from the daily fee you can see and expect, but from the invisible line you crossed on day nine. Write the ceiling down as a number before you go, and check your consumption once mid-trip rather than after you get home.

The cheaper way on longer trips

The facts

Method
Local or regional data eSIM
Your UK line
Stays on for calls and texts
Worth it past
A few days away
Reverses
In seconds, on return

What it means for you

Keep your UK number live for calls and texts, and add a cheap local or regional data profile at the destination with data routed through it.

On any stay past a few days this comfortably beats daily roaming charges, and the whole arrangement undoes itself in seconds when you land back home. It needs a phone that supports two profiles, which most recent flagships do.

Five minutes before you fly

The facts

Check
Spend cap is on
Write down
Your fair-use ceiling
Turn off
Backups and updates over mobile data
Before boarding a boat
Turn mobile data off entirely

What it means for you

  1. Confirm the spend cap is enabled.
  2. Read the roaming screen and note the ceiling as a figure.
  3. Turn off automatic backups and app updates over mobile data.
  4. Buy a travel data profile if the trip runs past a few days.
  5. On landing, check which network you have latched onto and that data routes as intended.
Watch thisFerries, cruise ships and some aircraft bill through satellite systems that sit outside ordinary roaming and outside your spend cap. This is the single biggest source of shocking bills, and switching mobile data off before boarding prevents every one of them.
