About this site

How we choose travel tools

Practical use, honest limits, no paid placement. This page explains how recommendations are made and what this site does not do.

Last updated: May 2026

What drives recommendations

Practical fit for the traveller's actual situation — trip length, data use, starting country.
Transparency of plan terms — data limits, fair use policy, hotspot restrictions clearly stated.
Setup process — can it be done before departure without friction.
Known limits — what the product does not do, when to avoid it.
Regulatory context — restrictions that affect usability at the destination (e.g. Turkey BTK registration requirement).

Review rating framework — provider reviews

Each provider review on this site is scored against four fixed criteria. Scores run from 1 to 5 per criterion. No aggregate score is published. A single number would force an apples-to-apples comparison between fundamentally different products — a data-only eSIM is not "worse" than a voice-enabled one for a traveller who only wants data. The four scores are surfaced individually so the reader weighs the criteria that matter for their trip.

The criteria are designed to be verifiable: they describe what the provider publishes, what its terms say, and what its service offers — not subjective impressions of speed, support quality or app polish, and not regulatory restrictions imposed by third-party jurisdictions which are not attributable to the provider as a brand. Regulatory and access restrictions (e.g. Turkey BTK block, UAE VoIP rules) are documented factually in the body of each review when relevant, without entering the score.

CRITERION → SCALE (1 / 3 / 5)
1. Coverage breadth
Destinations covered + regional packs offered.
→1 — fewer than 50 destinations, 0–1 regional pack. 3 — 100–150 destinations, 2–4 regional packs. 5 — 200+ destinations, 5+ regional packs.
2. Plan terms transparency
Fair use, hotspot, validity, restrictions stated before purchase.
→1 — terms vague or buried in T&C. 3 — terms readable but per-destination details require digging. 5 — full terms public, per-destination, no surprises after purchase.
3. Unlimited plans transparency
How honestly the provider communicates the behaviour of its unlimited offering, including operator dependency.
→1 — unlimited advertised with no information on actual behaviour. 3 — unlimited advertised with a "headline" threshold but no acknowledgement that real behaviour varies by partner operator. 5 — unlimited advertised with either (a) a numeric threshold plus explicit mention that behaviour varies by partner operator, OR (b) a public statement that the fair use policy is delegated to the partner operator with an invitation to consult its conditions. N/A — provider does not offer unlimited plans.
4. Hotspot policy transparency
How honestly the provider communicates its tethering policy, including operator dependency.
→1 — hotspot prohibited or restricted without transparency on the conditions. 3 — hotspot allowed with vague wording ("supported") and no further detail. 5 — hotspot policy stated with either (a) precise wording (uncapped, numeric cap) plus mention of partner-operator dependency, OR (b) a public statement that hotspot behaviour depends on the local operator.

Why these four and not others. The framework deliberately excludes four criteria commonly used in eSIM reviews:

Speed — depends on the local partner operator at the destination, varies per country, not attributable to the provider as a brand.
Customer support — not verifiable at scale without anecdotal evidence; vulnerable to selection bias in user reports.
Price — PAYG, fixed-plan and unlimited models are not directly comparable; the per-GB framing favours one model over another.
App or website UX — subjective, changes with releases, not a structural property of the service.

The framework is versioned. Changes — addition or removal of criteria, scoring scale adjustments — are documented here and dated.

Review rating framework — marketplaces

Marketplaces (MobiMatter, SimOptions, others) aggregate plans from third-party providers. They do not operate their own network, they do not write their own fair use policy, and they do not control hotspot terms. Scoring them on the provider framework above produces "N/A" on most criteria, which is a signal that the wrong object is being evaluated. A separate framework applies.

The marketplace framework evaluates what a marketplace actually controls: how broad its catalogue is, how clearly it exposes the underlying provider, how completely it surfaces plan terms before purchase, how usefully it lets the reader filter the offer, and how cleanly it splits responsibility with the underlying provider when something goes wrong.

CRITERION → SCALE (1 / 3 / 5)
1. Catalogue breadth
Number of underlying providers and plans aggregated.
→1 — fewer than 5 providers or under 100 plans. 3 — 10–20 providers, around 500 plans. 5 — 30+ providers, 1000+ plans.
2. Underlying provider disclosure
Whether the actual provider behind each plan is identified before purchase.
→1 — provider hidden until after purchase. 3 — provider named but plan details aggregated without context. 5 — provider clearly named before purchase, with reference or link to its own terms.
3. Plan terms passthrough
Whether fair use, hotspot, validity and restrictions are visible before purchase.
→1 — terms absent or replaced by "see provider". 3 — main terms shown but partial or inconsistent across plans. 5 — fair use, hotspot, validity and restrictions surfaced systematically per plan.
4. Filter granularity
Ability to sort and filter the catalogue by criteria that matter for a real trip.
→1 — sort by price only. 3 — basic filters (country, data volume). 5 — advanced filters (provider, hotspot, fair use threshold, validity, voice/data).
5. Support architecture clarity
Whether the reader knows who to contact if something goes wrong.
→1 — ambiguous; marketplace and provider deflect to each other. 3 — marketplace support documented but the provider's responsibility scope is unclear. 5 — marketplace support and provider support both documented, with clear scopes.

Why these five and not others. Price is not a marketplace property — comparing PAYG, fixed-plan and unlimited plans within the same catalogue is a methodological trap. Speed, fair use and hotspot belong to the underlying provider. App or website UX is subjective and changes with releases.

How eSIM providers are ranked

Each destination page shows the three most relevant eSIM providers for that country. The selection and order are determined by an algorithmic scoring system applied to sourced pricing and plan data, not by editorial opinion or affiliate commission rates.

The scoring evaluates three positions independently: best price per GB for the destination, best overall value (price, data volume, validity), and best unlimited plan where available. A diversity rule prevents the same provider from occupying more than one position, ensuring the three cards represent distinct options.

Pricing data is sourced directly from provider websites and stored centrally. A provider with no affiliate arrangement can rank first. A provider with an affiliate arrangement can rank last or not appear at all.

How VPN, password and cloud tools are selected

Tools in the VPN, password manager and cloud storage sections are assessed on usefulness for the travel context specifically — not general software reviews.

VPN — evaluated on protocol transparency, no-log policy audit status, server locations relevant to travel, and usability on mobile without friction.
Password managers — evaluated on cross-device availability, offline access capability, and whether the app works without internet in transit.
Cloud storage — evaluated on offline access, file format compatibility, and whether free tiers are practically usable for document backup.

What this site does not do

No paid placement — no provider can pay TDK to rank higher or to influence our editorial judgement.
No recommendation of an eSIM when roaming is clearly sufficient — the roaming guide says this explicitly.
No invented prices — all prices are marked as requiring verification before purchase.
No omission of known limits — fair use policies, hotspot caps, and country restrictions are stated.

Origin-neutral editorial policy

English pages on this site are written for travellers coming from any country. Roaming rules, carrier examples and starting-point guidance include travellers from the USA, Canada, UK, Australia, Asia, the Middle East and Africa.

How content is kept current

Each page carries a "Last checked" date.
Regulatory changes (such as the Turkey BTK eSIM registration requirement) are added as priority updates.
Prices are not presented as definitive — readers are directed to verify with providers before purchase.
