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.
- First/only line charged each US calendar date.
- Domestic allowances and overage or speed restrictions continue to apply.
- The fee limit is per billing cycle, not per calendar month.
- Domestic data must remain sufficient; beyond-allowance domestic restrictions apply.
- 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
1 GB requested per day. A single billing cycle is assumed. Home-plan subscription is excluded. Choose an included-roaming profile only if its eligibility applies to you.
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.

Calls, texts and other use can trigger roaming charges under the carrier terms. Disabling data roaming alone does not settle every billing condition.
Read carrier sourcesSet the right data line
Follow the travel eSIM's activation and roaming instructions. Check your home line and automatic data switching separately.
Review phone compatibilityDomestic subscription is already held and excluded from incremental travel cost. Seven charged travel days and 7GB requested data fall within one home billing cycle. No prior banked credits, promotional free days, rewards or prior account roaming spend. Terrestrial consumer postpaid roaming only; no business, prepaid, aircraft or ship use. No home-plan migration or consent to exceed a spending cap. First/only line charged each US calendar date. Domestic allowances and overage or speed restrictions continue to apply. Advertised roaming fees exclude any applicable international roaming taxes; actual tax depends on the account and jurisdiction.
Included-plan eligibility: Current eligible Unlimited plans include Mexico. Elite 2.0 international allowance and Premium/Elite Latin America benefits can make other subscribers pay less. The discount for additional lines on the same US date is excluded from this single-line reference.

AT&T roaming questions
What does the AT&T comparison include?
This page uses the Extra 2.0 consumer postpaid line with International Day Pass and at least 7GB domestic allowance available 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.
