Review phone compatibilityExisting consumer postpaid subscription is already held; its domestic monthly charge is excluded. All charged travel days fall within one billing cycle, with no earlier roaming use. Personal terrestrial smartphone data only; calls, texts, aircraft, maritime and satellite use are excluded. Sufficient domestic data remains within the 25GB monthly roaming fair-use limit. Spend Manager and roaming bars must permit daily charges; a £0 cap can block them. Opted-in Roaming Pass Extras are outside Spend Manager.
Included-plan eligibility: Euro Roam includes zones A/B; Global Roam includes A/B/C. Included usage still needs domestic allowance and observes the 25GB monthly fair-use limit. Older contracts can have different charges.

For the same trip and requested data amount, we divide the carrier roaming cost per requested GB by the eSIM package cost per requested GB.

We describe caps and conditions separately and do not claim equal performance.
Yes. An eligible home plan may include roaming, or a carrier add-on may cost less for the selected trip. Those results remain visible. The comparison excludes the home-plan subscription and does not assume every customer qualifies for an included benefit.
A rank requires current, comparable costs for the complete standard destination basket. Missing eligibility, unavailable source facts, an insufficient data allowance or expired checks leave a carrier unranked. An unknown price is never treated as zero.
This edition compares published carrier tariffs and source-checked retail eSIM packages. It does not use physical activation tests, measured speeds or a reliability score. Prices, coverage, eligibility and checkout terms can change.
