Assumptions, billing and sources
7 GB requested over 7 days. Unit costs divide both trip prices by the same requested GB. Unused allowance and speed limits are described separately; this is not a speed test.
- Enough of the 60GB monthly EU allowance remains for the requested data.
- Pass days follow Irish charging dates: a seven-day pass can expire earlier than 168 hours after arrival.
- No prior roaming-data spend; any lower customer-set cap or roaming bar must permit the purchase.
- Data only. Purchase in advance and deliberately add a new pass after expiry; these passes do not auto-renew.
- Requested usage is spread over the stated number of Irish charging dates; this is not a promise of full 24-hour days.
- For a mixed sequence, add the next pass only after the earlier charging days expire; do not assume simultaneous passes extend one another.
- Quantity comparison: 1 GB each travel day. Network access, speed, calls and SMS are not equivalent.
- Quoted retail charges use the stated tax basis; account-specific taxes and checkout fees may change the amount paid.
- No earlier account roaming spend or additional-spend consent is assumed.
eSIM package conditions

- The provider feed says activation starts on first use.
- Data-only package. Traditional calls and SMS are not included. Optional app calling or separately purchased numbers are not included in this price.

Three Ireland roaming questions
What does the Three Ireland comparison include?
This page uses the Three SIM Flex 5G 30 Day consumer Bill Pay, with its 60GB EU allowance; no legacy €3.99 roaming pass. reference profile, the dated carrier sources and the standard trip shown in the table. It excludes the home-plan subscription. Included-roaming profiles apply only when their verified eligibility matches your plan.
How is the roaming cost multiple calculated?
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. Because both sides use the same denominator, the multiple is also the roaming trip price divided by the eSIM package price. A package may include unused data. We describe caps and conditions separately and do not claim equal performance.
Is roaming ever cheaper than an eSIM?
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.
Why is a carrier not ranked?
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.
Have you physically tested these eSIMs?
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.
