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.
- The existing domestic subscription is excluded from incremental travel cost.
- One chargeable use period is assumed per travel day. Usage starts are assumed to align with the provider’s stated billing periods.
- The trip falls within one home billing cycle. Consumer postpaid only; prepaid, business, flights and cruises are excluded.
- All ten reference countries are explicitly listed in Telstra Zone 2.
- On Upfront, the pass starts at eligible use and runs for 24 hours; older non-Upfront plans can use AEST calendar-day billing. This edition uses Upfront.
- Calls, outgoing SMS and background data may trigger a pass. Receiving an SMS alone does not.
- 2GB per pass is sufficient for the requested 1GB/day; no top-up is assumed.
- 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.
eSIM package conditions
- Choose the exact allowance and validity on the destination page; this link does not preselect the UUID package.
- 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.
About these prices

Lowest-cost modeled eligible product or defined pack only. We do not combine arbitrary roaming add-ons. The eSIM comparison uses a limited, dated retail selection.
This edition uses 73 frozen reference packages selected from 362 qualifying fixed-data offers from 2 providers (Torisim, miesim.es), a limited catalog selection. Benchmark packages have explicit tax-included evidence. Incremental published retail charges. UK/Ireland tax-inclusive prices, Australian published consumer roaming charges and US/Canadian prices before account-specific taxes are retained as stated; tax treatment is disclosed by carrier. eSIM references have explicit tax-inclusive evidence. Ratios are comparisons of these quoted charges, not tax-normalized checkout bills.

Telstra roaming questions
What does the Telstra comparison include?
This page uses the Eligible Telstra Upfront mobile plan with International Roaming Day 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.
